Beaked groups like birds and turtles have caruncles, but snakes and nearly all lizards do not.
|
|
They can bleed and occasionally cause dysuria and dyspareunia. The caruncles can be removed by surgery, electric cauterization and then with suture repair. Pathology studies are necessary to distinguish carcinoma of the urethra from urethral caruncles. Caruncles can grow back in some instances.
|
|
The uterus contracts and the caruncular stock shrinks, further enhancing the separation of cotyledons from caruncles.
|
|
The caruncles are yellow, the eye-ring blue, the mouth orange and the bill is light-grey.

After the breeding season, the plumage fades, the eye-ring becomes lead-blue, and the caruncles become smaller and duller-colored. Juveniles are dark brown with varying amounts of white underneath and brown iris, bill, and feet. They have no caruncles, and their eye-rings are lead-blue. They acquire adult plumage gradually.

Caruncles are also ornamental elements used by males to attract females to breeding. Having large caruncles or colorful bright ones indicates high levels of testosterone, that they are well-fed birds able to elude other predators thus showing the good quality of their genes. It has been proposed that these organs are also associated with genes which encode resistance to disease. It is believed that for birds living in tropical regions, the caruncles also play a role in thermoregulation, making the blood cool faster when flowing through them.

|
Urethral caruncles can accompany the skin changes related to lowered estrogen levels. They can become a source of chronic hematuria, infection, and urethritis.
|
|
Caruncles are carnosities, often of bright colors such as red, blue, yellow or white. They can be present on the head, neck, throat, cheeks or around the eyes of some birds. They may be present as combs or crests and other structures near the beak, or, hanging from the throat or neck. Caruncles may be featherless, or, have small scattered feathers.
|
|
In the context of Muscovy ducks, caruncles refer to the red fleshy mask that surrounds the head of adult birds, particularly prominent in adult drakes (males).
|
|
Usually they are pale, but when the male becomes excited or during courtship, the caruncles, wattle and snood all engorge with blood, become bright red or blue, and enlarge. The beard (a tuft of modified brush-like feathers) also becomes erect.

The genus Neodrepanis is characterised by a tiny body with a short tail, a fine, strongly decurved bill and, during the breeding season, strong sexual dichromatism. Males in breeding plumage are brilliant blue and black above and variably bright yellow below, with extraordinary blue and green facial caruncles. Females, males in non-breeding plumage and immatures are dull blue- green above, lack caruncles and are variably yellowish below; some female- plumaged birds (at least for Common Sunbird Asity) have a half-sized caruncle and may be immature males. In winter, males are often seen with traces of breeding plumage coloration.

They can be distinguished from Foveaux shags by their facial ornamentation in the breeding season: Foveaux shags have dark orange papillae on their face, whereas Otago shags have both papillae and small bright orange facial caruncles above the base of the bill.
|
|
In some species, they may form pendulous structures of erectile tissue, such as the "snood" of the domestic turkey. Caruncles are sometimes secondary sexual characteristics, having a more intense color or even a different color, developing as the male reaches sexual maturity.

Major caruncle, 5. Beard A caruncle is defined as 'a small, fleshy excrescence that is a normal part of an animal's anatomy'. Within this definition, caruncles in birds include wattles (or dewlaps), combs, snoods, and earlobes. The term caruncle is derived from Latin caruncula, the diminutive of carō, "flesh".

On the undersurface of the tongue is a fold of mucous membrane called the frenulum that tethers the tongue at the midline to the floor of the mouth. On either side of the frenulum are small prominences called sublingual caruncles that the major salivary submandibular glands drain into.

Auckland Museum It is a large (76 cm long, 2.5 kg in weight) black and white cormorant with pink feet. White patches on the wings appear as bars when the wings are folded. Yellow-orange swellings (caruncles) are found above the base of the bill. The grey gular pouch is reddish in the breeding season.

In some birds, caruncles are erectile tissue and may or may not have a feather covering.John James Audubon, Dean Amadon, John L Bull. 1967 The Birds of AmericaRichard Bowdler Sharpe. 1888. Catalogue of the Birds in the British Museum, British Natural History Museum, Department of Zoology Wattles are often such a striking morphological characteristic of animals that it features in their common name.

The Heard Island shag has largely black upperparts and white underparts. The cheeks and ear-coverts are white; there are white bars on the wings, a black, recurved crest over the forehead, and pink feet.Marchant & Higgins (1991), p.854. A breeding adult has a pair of orange caruncles above the base of the bill in front of the eyes as well as blue eye- rings.

Snoods are just one of the caruncles (small, fleshy excrescences) that can be found on turkeys. While fighting, commercial turkeys often peck and pull at the snood, causing damage and bleeding. This often leads to further injurious pecking by other turkeys and sometimes results in cannibalism. To prevent this, some farmers cut off the snood when the chick is young, a process known as desnooding.

The 3 lateral caruncles have club-shaped glands that secrete a slime containing luminous granules. Adult females have jet-black pigmentation while juveniles are dark brown. The triplewart seadevil uses an illicium, a modified dorsal spine on the snout, to lure prey. This apparatus is primarily composed of a terminating esca or lure supported by an extremely long pterygiophore bone encased in a dermal sheath.

A Silver Ameraucana cock with a pea comb, typical to the breed A pea comb is one type of chicken combs. It manifests as three connected rows of caruncles in the form of conjoined pea-like protrusions. Pea combs begin at the base of the beak and extend towards the top of a chicken's head. Pea combs are smaller than other combs length-wise and do not extend upwards.

A rooster's wattles hang from the throat A wattle is a fleshy caruncle hanging from various parts of the head or neck in several groups of birds and mammals. Caruncles in birds include those found on the face, wattles, dewlaps, snoods and earlobes. Wattles are generally paired structures but may occur as a single structure when it is sometimes known as a dewlap. Wattles are frequently organs of sexual dimorphism.
|

The face and throat pouch are dark brown, ornamented with yellow-orange tubercles. The bill is horn-colored or brown; the eyes are hazel. The legs and feet vary from dark brown to dark-blotched bright pink. Breeding adults have a little black erectile crest on the forehead, yellow or orange caruncles (large warts) above the base of the bill, and a bright blue ring around the eye.
|
|
Domesticated birds may look similar; most are dark brown or black mixed with white, particularly on the head. Other colors such as lavender or all-white are also seen. Both sexes have a nude black-and-red or all-red face; the drake also has pronounced caruncles at the base of the bill and a low erectile crest of feathers. C. moschata ducklings are mostly yellow with buff-brown markings on the tail and wings.
|
|
Adults have a red and orange-red caruncles on the face and the gape of the mouth. In spite of the common name of the genus the iris of the eye is brown, and the eye has a violet eye-ring. The bill is dark grey, with a bright red mouth, and the legs and feet are dull pink. Non-breeding birds look similar to breeding birds but are duller, have no crest or filoplumes, and duller bare parts.

Gould's wild turkey with non-erected snood and wattle. In turkeys, the term usually refers to small, bulbous, fleshy protuberances found on the head, neck and throat, with larger structures particularly at the bottom of the throat. The wattle is a flap of skin hanging under the chin connecting the throat and head and the snood is a highly erectile appendage emanating from the forehead. Both sexes of turkey possess caruncles, although they are more pronounced in the male.

The Macquarie shag has largely black upperparts and white underparts. The upper cheeks and ear- coverts are black; there are white bars on the wings, a black, recurved crest over the forehead, and pink feet.Marchant & Higgins (1991), p.867. A breeding adult has a pair of orange caruncles above the base of the bill in front of the eyes, orange-brown facial skin at the base of the lower mandible, as well as blue eye-rings.
|
|
Collectively, these and other fleshy protuberances on the head and throat are called caruncles. Both the adult male and female have wattles and combs, but in most breeds these are more prominent in males. A muff or beard is a mutation found in several chicken breeds which causes extra feathering under the chicken's face, giving the appearance of a beard. Domestic chickens are not capable of long distance flight, although lighter chickens are generally capable of flying for short distances, such as over fences or into trees (where they would naturally roost).

Fossil of Axelrodichthys araripensis, an extinct coelacanthiform Latimeria chalumnae embryo with its yolk sac from the Muséum national d'histoire naturelle Coelacanths are ovoviviparous, meaning that the female retains the fertilized eggs within her body while the embryos develop during a gestation period of over a year. Typically, females are larger than the males; their scales and the skin folds around the cloaca differ. The male coelacanth has no distinct copulatory organs, just a cloaca, which has a urogenital papilla surrounded by erectile caruncles. It is hypothesized that the cloaca everts to serve as a copulatory organ.

A rooster with a large red comb A comb is a fleshy growth or crest on the top of the head of gallinaceous birds, such as turkeys, pheasants, and domestic chickens. Its alternative name cockscomb (with several spelling variations) reflects that combs are generally larger on males than on females (a male gallinaceous bird is called a cock). There can be several fleshy protuberances on the heads and throats of gallinaceous birds, i.e. the comb, wattle, and earlobe, which collectively are called caruncles, however, in turkeys caruncle refers specifically to the fleshy nodules on the head and throat.

In addition to the three basic seed parts, some seeds have an appendage, an aril, a fleshy outgrowth of the funicle (funiculus), (as in yew and nutmeg) or an oily appendage, an elaiosome (as in Corydalis), or hairs (trichomes). In the latter example these hairs are the source of the textile crop cotton. Other seed appendages include the raphe (a ridge), wings, caruncles (a soft spongy outgrowth from the outer integument in the vicinity of the micropyle), spines, or tubercles. A scar also may remain on the seed coat, called the hilum, where the seed was attached to the ovary wall by the funicle.

Male domesticated turkey sexually displaying by showing the snood hanging over the beak, the caruncles hanging from the throat, and the 'beard' of small, black, stiff feathers on the chest Turkeys are large birds, their nearest relatives being the pheasant and the guineafowl. Males are larger than females and have spreading, fan-shaped tails and distinctive, fleshy wattles, called a snood, that hang from the top of the beak and are used in courtship display. Wild turkeys can fly, but seldom do so, preferring to run with a long, straddling gait. They roost in trees and forage on the ground, feeding on seeds, nuts, berries, grass, foliage, invertebrates, lizards, and small snakes.
