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".

The lacrimal caruncle, or caruncula lacrimalis, is the small, pink, globular nodule at the inner corner (the medial canthus) of the eye. It is made of skin covering sebaceous and sweat glands. With ocular allergies, the lacrimal caruncle and the plica semilunaris of the conjunctiva may be inflamed and pruritic (itchy) due to histamine release in the tissue and tear film.

Picture of the mouth showing the sublingual caruncle and related anatomical structures It arises from deep part of submandibular salivary gland . It begins by numerous branches from the superficial surface of the gland, and runs forward between the mylohyoid, hyoglossus, and genioglossus muscles. It then passes between the sublingual gland and the genioglossus and opens by a narrow opening on the summit of a small papilla (the "sublingual caruncle") at the side of the frenulum of the tongue. It lies superior to lingual and hypoglossal nerves.

Moreover, some polychaete prostomia have a posterior extension or ridge with sensory function, called a caruncle. Another sensory organ, the nuchal organ (or a variation, the nuchal epaulette), is a chemosensory, ciliated pit or groove at the posterior end of the prostomium.
|
|
The central wattle is large and may possibly be erectile. The three wattles terminate in tufts of filoplumes. At the base of the beak and below the wattle is a fleshy caruncle which is whitish. The bill is olive yellow, brightening to dull orange towards the base.

Large and predominantly white, the king vulture has gray to black ruff, flight, and tail feathers. The head and neck are bald, with the skin color varying, including yellow, orange, blue, purple, and red. The king vulture has a very noticeable orange fleshy caruncle on its beak. This vulture is a scavenger and it often makes the initial cut into a fresh carcass.
|
|
In some seeds, a basal ridge may be present, and rarely in section Adenotrias an apical caruncle is present which attracts ants to disperse seeds. Some species have highly specific germination and survival condition requirements. For example, H. lloydii is susceptible to a fungal infection as a seedling if conditions are too moist, whereas other species including H. chapmanii can grow underwater.
|

Its oval-shape fruit are 4.5-7 by 3-4 centimeters. The fruit are covered in pyramid-shaped bumps arranged in a spiral pattern and dense rust-colored hairs. The fruit have a groove opposite their attachment point, and terminate in a woody, hooked point. Its immature, smooth, brown seeds are 9-10 by 4-5 millimeters, and have a prominent caruncle at their base.

Major caruncle, 5. Beard In anatomical terms, the snood is an erectile, fleshy protuberance on the forehead of turkeys. Most of the time when the turkey is in a relaxed state, the snood is pale and 2–3 cm long. However, when the male begins strutting (the courtship display), the snood engorges with blood, becomes redder and elongates several centimetres, hanging well below the beak (see image).
|
|
Its cylindrical carpels are 1-1.5 millimeters long and hairless. Its fruit are on 1.5-4 centimeter long, hairy pedicels. Its fruit are dark yellow, oval to round, 1.7-3 centimeters in diameter, hairless and have an outer surface that has a network pattern. Its numerous seeds are brown, oval, flat and 7-9 by 3-4 millimeters with a caruncle at one end.

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 adult Antarctic shag is about 75–77 cm tall, has a wingspan of 124 cm, and weighs 1.5-3.5 kg. When looking at individuals within this species, the most defining characteristic is the warty yellow caruncle found on the forehead. Additionally, the blue eye, which is actually blue skin surrounding the eye, is a distinct trait that stands out about these birds. The head, wings, and outside of the thighs are black.

There is a dark red caruncle (or comb) on the top of the head of the adult male. Adult female at Franklin Park Zoo, Boston, Massachusetts, US Detail of talon showing elongated middle toe Although the California condor is, from beak to tail, about longer, the Andean condor has a wider wingspan, which ranges from . It is also typically heavier, reaching a weight of for males and for females. Overall length can range from .

The head and neck are nearly featherless, and are a dull red color, which may flush and therefore change color in response to the bird's emotional state. In the male, there is a wattle on the neck and a large, dark red comb or caruncle on the crown of the head. The female condor is smaller than the male, an exception to the rule among birds of prey. The condor is primarily a scavenger, feeding on carrion.

Sebaceous carcinoma is a skin cancer of the sebum producing glands. It is predominantly seen in the head and neck region, representing 25% of all reported lesions in this area. The periocular region, which includes the meibomian gland, caruncle, gland of Zeis and eyebrow, is one of the most common sites in which SC is observed. The meibomian gland is a type of sebaceous gland that lines the upper and lower eyelids, and does not contain a follicle.

Ciaccio's glands or Wolfring's glands are small tubular accessory lacrimal glands (glandulae lacrimales accessoriae) found in the lacrimal caruncle of the eyelid. These accessory lacrimal glands are located in the upper border of the tarsus, approximately in the middle between the extremities of the tarsal glands. Sometimes they are situated slightly above the tarsus. There are usually 2 to 5 of these glands in the upper eyelid, and their function is to produce tears which are secreted onto the surface of the conjunctiva.

The Siamese fireback (Lophura diardi) also known as Diard's fireback, is a fairly large, approximately 80 cm long, pheasant. The male has a grey plumage with an extensive facial caruncle, crimson legs and feet, ornamental black crest feathers, reddish brown iris and long curved blackish tail. The female is a brown bird with blackish wing and tail feathers. Head Lophura diardi The Siamese fireback is distributed to the lowland and evergreen forests of Cambodia, Laos, Thailand and Vietnam in Southeast Asia.

Male common sunbird-asities are duller than yellow-bellied in almost all respects. The former have brilliant royal blue- fringed back crown, nape, mantle and scapular feathers, and narrow but fairly conspicuous yellow fringes to the secondaries and greater and median wing coverts. Their underparts are dull, deep yellow, with strong olive-brown streaking in the centre of the breast; the flanks, belly and undertail coverts are unstreaked and somewhat brighter. The caruncle is almost square and turquoise-blue, rather greener around the eye.

Nectar glands usually occur in fives, may be as few as one, and may be fused into a "U" shape. The cyathophylls often occur in twos, are leaf-like, and may be showy and brightly coloured and attractive to pollinators, or be reduced to barely visible tiny scales. The fruits are three- or rarely two-compartment capsules, sometimes fleshy, but almost always ripening to a woody container that then splits open, sometimes explosively. The seeds are four-angled, oval, or spherical, and some species have a caruncle.

Its colors are varied and range from greenish, to yellowish, to reddish, grayish through white with a pearly glow. The body consists of 60 to 150 identical segments separated from each other by a thin white line and protected by cuticles. Each segment has a pair of parapodia, a structure for locomotion, clusters of stinging white bristles, and red or orange gills all in bilateral position. The anterior part of the worm can be recognized by small growths, called caruncle, which have the same color of the gills on the first four segments.

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.

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 stark contrast, the wing coverts, flight feathers and tail are dark grey to black, as is the prominent thick neck ruff. The head and neck are devoid of feathers, the skin shades of red and purple on the head, vivid orange on the neck and yellow on the throat. On the head, the skin is wrinkled and folded, and there is a highly noticeable irregular golden crest attached on the cere above its orange and black bill; this caruncle does not fully form until the bird's fourth year. The king vulture has, relative to its size, the largest skull and braincase, and strongest bill, of the New World vultures.

Female at Doué-la-Fontaine Zoo, France Male at the Cincinnati Zoo The adult plumage is all black, except for a frill of white feathers at the base of the neck and, especially in the male, large white bands on the wings, which only appear after the bird's first moult. The head and neck, kept meticulously clean, are red to blackish-red, and have few feathers. Their baldness means the skin is more exposed to the sterilizing effects of dehydration and high-altitude UV light. The crown of the head is flattened, and (in the male) is topped by a dark red comb (also called a caruncle); the skin hanging from its neck is called a wattle.
