Boa constrictors are very popular within the exotic pet trade and have been both captured in the wild and bred in captivity. Today, most captive boa constrictors are captive-bred, but between 1977 and 1983, 113,000 live boa constrictors were imported into the United States. These huge numbers of wild-caught snakes have put considerable pressure on some wild populations. Boa constrictors have also been harvested for their meat and skins, and are a common sight at markets within their geographic range.

Some individuals exhibit pigmentary disorders, such as albinism. Although these individuals are rare in the wild, they are common in captivity, where they are often selectively bred to make a variety of different color "morphs". Boa constrictors have an arrow-shaped head with very distinctive stripes on it: One runs dorsally from the snout to the back of the head; the others run from the snout to the eyes and then from the eyes to the jaw. A juvenile South American boa constrictor Boa constrictors can sense heat via cells in their lips, though they lack the labial pits surrounding these receptors seen in many members of the family Boidae.

The Inferior pharyngeal constrictor, the thickest of the three constrictors, arises from the sides of the cricoid and thyroid cartilage. Similarly to the superior and middle pharyngeal constrictor muscles, it is innervated by the vagus nerve (cranial nerve X), specifically, by branches from the pharyngeal plexus and by neuronal branches from the recurrent laryngeal nerve.
|
|
The middle pharyngeal constrictor is a fan-shaped muscle located in the neck. It is one of three pharyngeal constrictors. Similarly to the superior and inferior pharyngeal constrictor muscles, the middle pharyngeal constrictor is innervated by a branch of the vagus nerve through the pharyngeal plexus. The middle pharyngeal constrictor is smaller than the inferior pharyngeal constrictor muscle.
|
|
The superior pharyngeal constrictor muscle is a muscle in the pharynx. It is the highest located muscle of the three pharyngeal constrictors. The muscle is a quadrilateral muscle, thinner and paler than the inferior pharyngeal constrictor muscle and middle pharyngeal constrictor muscle. The muscle is divided into four parts: A pterygopharyngeal, buccopharyngeal, mylopharyngeal and a glossopharyngeal part.

Other factors which can affect decompression risk include oxygen concentration, carbon dioxide levels, body position, vasodilators and constrictors, positive or negative pressure breathing. and dehydration (blood volume). Individual susceptibility to decompression sickness has components which can be attributed to a specific cause, and components which appear to be random. The random component makes successive decompressions a poor test of susceptibility.

Clinical signs may vary, with regurgitation and neurological symptoms being the most prominent in the early and later stages of its progression, respectively. In boa constrictors, the first signs may include off-and-on regurgitation followed by inappetence, and some develop head tremors. Abnormal shedding may occur. Some develop chronic regurgitation and anorexia (lack of appetite or refusal to feed).

It is a member of the "big four" species, inflicting the most snakebites on humans in India. Rat snakes (or ratsnakes) are members – along with kingsnakes, milk snakes, vine snakes and indigo snakes – of the subfamily Colubrinae of the family Colubridae. They are medium to large constrictors and are found throughout much of the Northern Hemisphere. They feed primarily on rodents and birds.

Killian's dehiscence (also known as Killian's triangle) is a triangular area in the wall of the pharynx between the cricopharyngeus and thyropharyngeus which are the two parts of the inferior constrictors(also see Pharyngeal pouch). It can be seen as a locus minoris resistentiae. Similar triangular area between circular fibres of cricopharyngeus and longitudinal fibres of esophagus is Lamier's triangle or Lamier-hackermann's area.

Nesting cavity competition with red-necked amazons and owls creates a tough living environment for imperial amazons. They mate only for a couple of months of the year, and guard their nests the rest of the year. A good quality nesting site is key to the survival and upbringing of their offspring. Imperial amazons are preyed on by boa constrictors, broad-winged hawks, common opossums and rats.

Elaphe is a genus of snakes in the family Colubridae. Elaphe is one of the main genera of the rat snakes, which are found in many regions of the northern hemisphere. Elaphe species are medium to large constrictors by nature. Although all of the species in Elaphe are nonvenomous, bites from rat snakes are still irritably painful and can potentially cause bacterial infections due to the saliva.

He removes the lid, then begins playing a flute-like instrument made from a gourd, known as a been or pungi. As if drawn by the tune, a snake eventually emerges from the container; if a cobra, it may even extend its hood. In the Western world snake charming is very different. Western style snake charmers use pythons and boa constrictors for their performances as they are not venomous.

The center also contains an amphitheater and an indoor classroom. Inside the center, exhibitions of reptiles and amphibians such as alligators, painted turtles, box turtles, and gopher tortoises, rattlesnakes, corn snakes, king snakes, boa constrictors, pythons, are held. The staff perform demonstrations of raptors in flight. In 2009, the center added an expansion known as the Wetland Preserve, featuring various species of water fowl in their native habitats.

Head shape of B. imperator The coloring of boa constrictors can vary greatly depending on the locality. However, they are generally a brown, gray, or cream base color, patterned with brown or reddish- brown "saddles" that become more pronounced towards the tail. This coloring gives B. constrictor species the common name of "red-tailed boas." The coloring works as a very effective camouflage in the jungles and forests of its natural range.

|
Specimens from Central America are more irascible, hissing loudly and striking repeatedly when disturbed, while those from South America tame down more readily. Like all snakes, boa constrictors in a shed cycle are more unpredictable, because the substance that lubricates between the old skin and the new makes their eyes appear milky, blue, or opaque so that the snake cannot see very well, causing it to be more defensive than it might otherwise be.
|
|
Captive boa constrictor strike- feeding on large (already dead) rat Their prey includes a wide variety of small to medium-sized mammals and birds. The bulk of their diet consists of rodents, but larger lizards and mammals as big as ocelots are also reported to have been consumed. Young boa constrictors eat small mice, birds, bats, lizards, and amphibians. The size of the prey item increases as they get older and larger.
|
|
The effects of central fusion and terminal fusion on heterozygosity Boa constrictors are viviparous, giving birth to live young. They generally breed in the dry season—between April and August—and are polygynous; thus, males may mate with multiple females. Half of all females breed in a given year, and a larger percentage of males actively attempt to locate a mate. Due to their polygynous nature, many of these males will be unsuccessful.
|
|
Relocation efforts continue; though at least a few birds seem to survive, the continuing existence of this species had not been verified as of January 2008.Curry (2008) Some scientists believe that other factors must have contributed to the bird's decline, because the Cozumel thrasher likely survived hurricanes for millennia. Introduced species, including predatory boa constrictors—which were released on the island in 1971 and are now abundant—may also have had a detrimental effect.

|
Predators recorded for jaguarundis include boa constrictors, cougars and domestic dogs. Parasites such as hookworms (Ancylostoma species), tapeworms (such as Spirometra and Toxocara species) and the lung fluke have been found in jaguarundis. Studies have mostly observed jaguarundis alone or in pairs; pairs could probably be formed between mothers and older kittens or between individuals of opposite sexes during the mating season. Individuals in captivity have been found to be more gregarious.

Surgical treatment is best, when it can be performed. Pressure within the portal vein is measured as the shunt is closed, and it must be kept below 20 cm H2O or else portal hypertension will ensue. Methods of shunt attenuation should aim to slowly occlude the vessel over several weeks to months in order to avoid complications associated with portal hypertension. These methods include ameroid ring constrictors, cellophane banding, intravascular or percutaneous silicone hydraulic occluders.

The pharyngeal raphe is a raphe that serves as the origin and insertion for several of the pharyngeal constrictors (thyropharyngeal part of the inferior pharyngeal constrictor muscle, middle pharyngeal constrictor muscle, superior pharyngeal constrictor muscle). Two sides of the pharyngeal wall are joined together posteriorly in the midline by the raphe. Its superior part is attached to the pharyngeal tubercle; it extends inferiorly to the level of vertebra C6 where it blends with the posterior wall of the esophagus.

Vipera berus, one fang in glove with a small venom stain, the other still in place Snakes do not ordinarily prey on humans. Unless startled or injured, most snakes prefer to avoid contact and will not attack humans. With the exception of large constrictors, nonvenomous snakes are not a threat to humans. The bite of a nonvenomous snake is usually harmless; their teeth are not adapted for tearing or inflicting a deep puncture wound, but rather grabbing and holding.

Male Canadian garter snakes huddle around a female after hibernation when mating. Huddling confers higher and more constant body temperatures than solitary resting. Some species of ectotherms including lizards and snakes, such as boa constrictors and tiger snakes, increase their effective mass by clustering tightly together. It is also widespread amongst gregarious endotherms such as bats and birds (such as the mousebird and emperor penguin) where it allows the sharing of body heat, particularly among juveniles.

The Darien Gap: Travels in the Rainforest of Panama is a non-fiction book, written by Canadian writer Martin Mitchinson, first published in August 2008 by Harbour Publishing. In the book, the author chronicles his 18-month expedition traveling the province of the Darién Gap, an area dangerous for human sojourns; a haven for Colombian guerrillas and drug-trafficking. The jungle is dense and teeming with caimans, boa constrictors, and jaguars. Mitchinson sailed into the province aboard his 36-foot ketch.

It is not uncommon for the mother to care for her young even weeks after they have hatched, remaining attentive to their calls and continuing to provide transportation. About five weeks after hatching, the young American crocodiles disband in search of their own independent lives. Most of them will not survive, being preyed upon by several types of raptorial birds, other reptiles, and large fishes (e.g., barred catfish, Atlantic tarpons, common snook and lemon sharks, boa constrictors, black spiny-tailed iguanas and spectacled caimans).

Ungaliophiinae is a subfamily of booid snakes containing two genera, Ungaliophis (2 species) and Exiliboa (1 species). They are small constrictors that are found in Central and South America, from southern Mexico to Colombia. They eat mostly lizards and frogs and are poorly studied. These snakes were formerly thought to be closely related to two other genera, Tropidophis and Trachyboa; all four genera were united in the family (Tropidophiidae) based on the presence of a tracheal lung and the absence of a left lung.

The region is home to many species of insects, some of which cause discomfort for travellers. Reptiles also are abundant, with numerous lizards and at least 60 known species of snakes, including many pit vipers and constrictors. The region is also home to many unique amphibians, including the iconic waxy monkey tree frog Phyllomedusa sauvagii that produces a waxy secretion to prevent drying out and coraline frog Leptodactylus laticeps that spends the dry season deep in a burrow, emerging with the rains to feed on other frogs.

The pharyngeal plexus, with fibers from CN IX, CN X, and cranial part of CN XI, innervates all the muscles of the pharynx (except stylopharyngeus, which is innervated directly by a branch of CN IX). This includes the following muscles: palatopharyngeus, palatoglossus, musculus uvulae, the pharyngeal constrictors, salpingopharyngeus plus others. Note that the intrinsic muscles of the larynx are innervated by the vagus nerve but not by the pharyngeal plexus. Instead, they are innervated by the recurrent laryngeal nerve and the external branch of the superior laryngeal nerve, branches of the vagus.

Rest in a cold environment will reduce inert gas exchange from skin, fat and muscle, whereas exercise will increase gas exchange. Exercise during decompression can reduce decompression time and risk, providing bubbles are not present, but can increase risk if bubbles are present. Inert gas exchange is least favourable for the diver who is warm and exercises at depth during the ingassing phase, and rests and is cold during decompression. Other factors which can affect decompression risk include oxygen concentration, carbon dioxide levels, body position, vasodilators and constrictors, positive or negative pressure breathing.

Inclusion body disease (IBD) is an infectious and invariably fatal viral disease affecting captive specimens of the boid family of snakes, particularly Boa constrictor. It has been recognized since the mid-1970s. It is so named because of the characteristic intracytoplasmic inclusions that are observed in clinical examinations in epidermal cells, oral mucosal epithelial cells, visceral epithelial cells, and neurons. In the 1970s and 1980s, the disease was most commonly observed in Burmese pythons (Python bivittatus). From the 1980s on, it has been most commonly observed in boa constrictors.

Taku continued to try to reach Venomm,Jungle Action #14 but when W'Kabi attempted to interrogate Venomm, Venomm attacked both of them and escaped. Venomm returned to his snakepit, and the Black Panther followed him there. Venomm sent a small army of constrictors and poisonous snakes against him, but Taku had followed the Black Panther, and when Venomm was unable to allow Taku to be harmed, he surrendered to the Black Panther.

In actuality, coachwhips are neither constrictors (snakes that dispatch their prey by suffocating with their coils) nor strong enough to overpower a person. Also, they do not whip with their tails, even though their tails are long and look very much like a whip. In parts of Mexico, where ranching is a way of life, these snakes are believed to wrap around the legs of cows and feed on their milk as if suckling leaving the nipple dry. They will also hook on any other mammal that produces milk, leaving the young baby dehydrated.

Reticulated python with an unusual color pattern: Various color patterns are found in captive-bred specimens – some brought about by selective breeding.In Ragunan Zoo, Terrarium, South Jakarta, Indonesia Increased popularity of the reticulated python in the pet trade is due largely to increased efforts in captive breeding and selectively bred mutations such as the "albino" and "tiger" strains. It can make a good captive, but keepers should have previous experience with large constrictors to ensure safety to both animal and keeper. Although its interactivity and beauty draws much attention, some feel it is unpredictable.

Once exported from Madagascar in great numbers, trade in A. dumerili has since been heavily restricted. The species is, however, quite prolific in captivity, and captive bred individuals are relatively inexpensive and easy to find in the exotic pet trade. Though its size makes it more suited to someone experienced with large constrictors, it has a typically docile nature, and readily feeds on rats. The main concern is that it is prone to stress, which can sometimes cause it to stop eating or can contribute to other health issues.

The three Briley brothers, Linwood (March 26, 1954 – October 12, 1984), James Jr. (June 6, 1956 – April 18, 1985) and Anthony (born February 17, 1958) were brought up by their parents in Richmond's Highland Park neighborhood. With their younger brother Anthony, Linwood and James were regarded by older neighbors as young people who would help them repair cars or mow lawns. The brothers collected exotic pets, such as tarantulas, piranhas, and boa constrictors. When the brothers reached their teenage years, Bertha and James split up and she moved away.

Further work which is critical of the USGS report on the expansion of the Burmese python was written by Dr, Frank Burbrink with the City University of New York which used more than annual rainfall and temperature to determine habitat suitable for the large constrictors. 19 variables were taken into consideration. Through the use of climatic data from the localities where the Burmese python is naturally found climatic models where generated to help predict where this species could inhabit. As a result, "the models suggest that the pythons are restricted to the vicinity of the Everglades in extreme south Florida…".

The WW females were likely produced by terminal automixis (see Figure), a type of parthenogenesis in which two terminal haploid products of meiosis fuse to form a zygote, which then develops into a daughter progeny. This is only the third genetically confirmed case of consecutive virgin births of viable offspring from a single female within any vertebrate lineage. In 2017, boa constrictors, along with Boa imperators and Burmese pythons, were found to contain a new set of sex determining chromosomes. Males were discovered to contain a pair of XY sex determining chromosomes, while females have a XX pair.

The female then gives birth to young that average in length. The litter size varies between females but can be between 10 and 65 young, with an average of 25, although some of the young may be stillborn or unfertilized eggs known as "slugs". The young are independent at birth and grow rapidly for the first few years, shedding regularly (once every one to two months). At 3–4 years, boa constrictors become sexually mature and reach the adult size of , although they continue to grow at a slow rate for the rest of their lives.

Inhabiting the Americas from southeastern Canada to southern Ecuador, Kingsnakes, of genus Lampropeltis, are constrictors that prey on many venomous snakes. In order to prey upon the venomous snakes, Kingsnakes have actually evolved a resistance rather than incrementally increasing their resistance to a point of immunity, like many species have. Kingsnakes resistance levels are currently known to be fixed for the duration of its life and have not been found to change with age or exposure. It is thought, that Kingsnakes have developed this evolutionary adaptation through a process called a co-evolutionary arms race with natural selection at the forefront.

More common than a complete absence of pigment cells is localized or incomplete hypopigmentation, resulting in irregular patches of white on an animal that otherwise has normal colouring and patterning. This partial leucism is known as a "pied" or "piebald" effect; and the ratio of white to normal-coloured skin can vary considerably not only between generations, but between different offspring from the same parents, and even between members of the same litter. This is notable in horses, cows, cats, dogs, the urban crowWhite crows at Cornell University. and the ball pythonPiebald ball pythons at Constrictors.

Other species include the golden- mantled tamarin (Saguinus tripartitus), jaguar (Panthera onca) and spectral bat (Vampyrum spectrum). Reptiles and amphibians include the yellow-footed tortoise (Chelonoidis denticulata), green iguana (Iguana iguana) and tegus lizards (Tupinambis species). The Caqueta moist forests are known for snakes such as emerald tree boa (Corallus caninus), fer-de-lance (Bothrops asper), palm vipers (Bothriechis species), common green racer (Philodryas viridissima), coral snakes (Micrurus species), boa constrictors (Boa constrictor) and bushmasters (Lachesis muta). 469 birds species have been recorded, including the endemic Chiribiquete emerald (Chlorostilbon olivaresi) and grey-legged tinamou (Crypturellus duidae).

The most common methods of attenuation used by veterinarians are ameroid ring constrictors and cellophane banding. Both methods have reportedly good outcomes in both cats and dogs, although the true composition of readily sourced cellophane has been found to be made from plastics (inert) and not cellulose (stimulates a fibrous reaction). Recently, a commercial supplier of regenerated cellulose based cellophane for veterinarians has been established for use of cellophane banding for portosystemic shunts in dogs and cats. Complete closure of extrahepatic shunts results in a very low recurrence rate, while incomplete closure results in a recurrence rate of about 50 percent.

The eggs and newly hatched young are most at risk and are preyed on by birds, snakes, rats, raccoons, and other mammals. Adults are protected by the bony osteoderms under the scales and their main predators are jaguars, green anacondas (Eunectes murinus), and large boa constrictors (Boa constrictor). The Cuvier's dwarf caiman is the only crocodilian species that seemingly does not perform the near-universal "death roll" technique used by other extant crocodilians for feeding or intra-specific combat. However, this may only be circumstantial, as specimens tested for the behavior may have been acting uncooperative with the researchers.

Diagram of the fossil of Sanajeh Madtsoiidae was first classified as a subfamily of Boidae, Madtsoiinae, in Hoffstetter (1961). Further study and new finds allowed ranking the group as a distinct family in Linnaean systems. With the recent use of cladistics to unravel phylogeny, various analyses have posited Madtsoiidae as a likely clade within Serpentes, or possible paraphyletic stem group outside Serpentes and within a more inclusive Ophidia. Madtsoiid snakes ranged in size from less than (estimated total length) to over , and are thought to have been constrictors analogous to modern pythons and boas, but with more primitive jaw structures less highly adapted for swallowing large prey.

The Curú Wildlife Refuge is a Wildlife refuge of Costa Rica, part of the Tempisque Conservation Area, tropical dry forests on the southern Nicoya Peninsula, near Tambor. Although it is a wildlife refuge it is also private property forming part of a ranch of 12.14 square kilometres. One third of the property is used for cattle breeding and growing crops such as soursop, guava, banana, mango and African oil palm, while the remaining two thirds retains its natural vegetation. The refuge protects the habitat of many types of birds, as well as animals such as white-tailed deer, mantled howler monkeys, Panamanian white-faced capuchin monkeys, coyotes, armadillos and boa constrictors.

Boa constrictors are ambush predators, so they often lie in wait for an appropriate prey to come along, then they attack. However, they have also been known to actively hunt, particularly in regions with a low concentration of suitable prey, and this behavior generally occurs at night. The boa first strikes at the prey, grabbing it with its teeth; it then proceeds to constrict the prey until death before consuming it whole. Unconsciousness and death likely result from shutting off vital blood flow to the heart and brain, rather than suffocation as was previously believed; constriction can interfere with blood flow and overwhelm the prey's usual blood pressure and circulation.

Wedge-capped capuchins have been observed to give alarm calls if they observe a potential predator. Such predators include jaguars, ocelots, tayras, boa constrictors, caimans, and collared peccaries. In addition, alarm calls have been observed when the capuchin sees one of several birds, such as hook-billed kites, black vultures, green ibises, rufous-vented chachalacas, harpy eagles, or ornate hawk-eagles. Due to these predators, the wedge-capped capuchin has taken to living in groups; as group size increases, vigilance per animal decreases, though it has not yet been demonstrated that capuchins in larger groups are any less vulnerable than those in smaller groups.

John Thomas Reid Price (November 13, 1912 – October 2, 1967) was a Major League Baseball shortstop who played in seven games for the Cleveland Indians during the 1946 Cleveland Indians season. He was known for delighting fans with his skills - such as batting while hanging upside-down or throwing three balls to three different players in one movement \- and was dubbed "the Clown Prince of Baseball" for his other antics which also included releasing a pair of five-foot Boa constrictors onboard a train. Price briefly teamed up with Max Patkin, another baseball clown; together they were described by Boston Red Sox manager Lou Boudreau as the "funniest show I ever saw". On October 2, 1967, Price committed suicide by hanging himself.

" In the summer of 2014, the United States Fish and Wildlife Service reopened its admission of comments on whether to list the five remaining species of snakes on the Lacey Act, including Boa constrictors. The HSUS then called upon its proponents to send in replies and letters to support further restriction of the trade in the reptiles. In response, USARK has accused the HSUS of directly telling its advocates to lie to the U.S. government: the reptile keepers association stating on their website that "HSUS President Wayne Pacelle is even asking HSUS followers to join in and lie to the U.S. Government by sending their sample letter." They continue their argument with "Their deceptive campaign continues because there is not valid, peer-reviewed science to support their claims.

Their poikilotherm metabolism has very low energy requirements, allowing large reptiles like crocodiles and large constrictors to live from a single large meal for months, digesting it slowly. While modern reptiles are predominantly carnivorous, during the early history of reptiles several groups produced some herbivorous megafauna: in the Paleozoic, the pareiasaurs; and in the Mesozoic several lines of dinosaurs. Today, turtles are the only predominantly herbivorous reptile group, but several lines of agamas and iguanas have evolved to live wholly or partly on plants. Herbivorous reptiles face the same problems of mastication as herbivorous mammals but, lacking the complex teeth of mammals, many species swallow rocks and pebbles (so called gastroliths) to aid in digestion: The rocks are washed around in the stomach, helping to grind up plant matter.

COTL1 has been shown to interact with ALOX5. ALOX5 is the first committed enzyme in the metabolism of arachidonic acid to an array of biologically important cell signaling agents: a) the pro- inflammatory mediator, leukotriene B4 (LTB4); b) the airways constrictors, LTC4, LTD4, and LTE4; c) the 5-hydroxyeicosatetraenoic acid family of pro- inflammatory and pro-allergic reactions mediators, 5-HETE and 5-oxo- eicosatetraenoic acid. ALOX5 also contributes to the metabolism of arachidonic acid and other polyunsaturated fatty acids to agents which act block inflammation and allergic reactions, the specialized pro-resolving mediators of the lipoxin and resolvin subclasses. Based on in vitro studies, COTL1 serves to stabilize ALOX5, acting as a chaperone or scaffold, to avert the enzyme's inactivation and thereby to promote its metabolic activity.

Some dry bites may also be the result of imprecise timing on the snake's part, as venom may be prematurely released before the fangs have penetrated the person. Even without venom, some snakes, particularly large constrictors such as those belonging to the Boidae and Pythonidae families, can deliver damaging bites; large specimens often cause severe lacerations, or the snake itself pulls away, causing the flesh to be torn by the needle-sharp recurved teeth embedded in the person. While not as life-threatening as a bite from a venomous species, the bite can be at least temporarily debilitating and could lead to dangerous infections if improperly dealt with. While most snakes must open their mouths before biting, African and Middle Eastern snakes belonging to the family Atractaspididae are able to fold their fangs to the side of their head without opening their mouth and jab a person.

The probability of xerostomia at one year increases by 5% for every 1Gy increase in dose to the parotid gland. Doses above 25–30 Gy are associated with moderate to severe xerostomia. Similar considerations apply to the submandibular gland, but xerostomia is less common if only one parotid gland is included in the radiated field and the contralateral submandibular gland is spared (less than 39 Gy) In the same manner, radiation dose to the pharyngeal constrictor muscles, larynx, and cricopharyngeal inlet determine the risk of dysphagia (and hence dependence on gastrostomy tube feeds). The threshold for this toxicity is volume-dependent at 55–60 Gy, with moderate to severe impairment of swallowing, including aspiration, stricture and feeding tube dependence above a mean dose of 47 Gy, with a recommended dose to the inferior constrictor of less than 41 Gy. Dose-toxicity relationships for the superior and middle constrictors are steep, with a 20% increase in the probability of dysphagia for each 10 Gy. For late dysphagia, threshold mean total constrictor doses, to limit rates of greater than or equal to grade 2 and 3 below 5% were 58 and 61 Gy respectively.
