The salt gland is an organ for excreting excess salts. It is found in the cartilaginous fishes subclass elasmobranchii (sharks, rays, and skates), seabirds, and some reptiles. Salt glands can be found in the rectum of sharks. Birds and reptiles have salt glands located in or on the skull, usually in the eyes, nose, or mouth.
The salt glands of mangroves such as Acanthus, Aegiceras, Aegialitis and Avicennia are a distinctive multicellular trichome, a glandular hair found on the upper leaf surface and much more densely in the abaxial indumentum. On the upper leaf surface they are sunken in shallow pits, and on the lower surface they occur scattered among long ...
In 1960 it was discovered at the Mount Desert Island Biological Laboratory in Salsbury Cove, Maine that sharks have a type of salt gland located at the end of the intestine, known as the "rectal gland", whose function is the secretion of chlorides. [52]
From their high-salt diet, they would lose more water and have a greater salt uptake. One way in which they osmoregulate is through the use of a salt gland, which is found in their beaks. [32] This salt gland helps excrete excess salt from the body through the nasal openings in the flamingo's beaks.
The salt is filtered from their blood and then excreted by specialised cranial exocrine glands at the nostrils, expelled from the body in a process much like sneezing. [8] [11] The marine iguana's cranium has an unusually large nasal cavity compared to other iguanas, which is necessary to accommodate the large salt glands. [14]
This species is only found on that continent, where it is widespread alongside the emperor penguin. ... Glands above their eyes filter the excess salt expelled through their beaks, keeping the ...
Salt glands are present in the tongues of crocodiles and they have a pore opening on the surface of the tongue, a trait that separates them from alligators. Salt glands are dysfunctional in Alligatoridae. [30] Their function appears to be similar to that of salt glands in marine turtles. Crocodiles do not have sweat glands and release heat ...
Procellariiforms drink seawater, so they have to excrete excess salt. All birds have an enlarged nasal gland at the base of the bill, above the eyes, and in the Procellariiformes the gland is active. In general terms, the salt gland removes salt from the system and forms a 5 percent saline solution that drips out of the nostrils, or is forcibly ...
