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.
Euryhaline organisms are commonly found in habitats such as estuaries and tide pools where the salinity changes regularly. However, some organisms are euryhaline because their life cycle involves migration between freshwater and marine environments, as is the case with salmon and eels .

In sharks, this includes a rectal gland that secretes salt to help the animal maintain osmotic balance with the seawater. The gland somewhat resembles a caecum in structure, but is not a homologous structure. [11] As with many aquatic animals, most fish release their nitrogenous wastes as ammonia. Some of the wastes diffuse through the gills.
Unlike fish, crabs and aquatic creatures, mammals and birds are usually found only sporadically in or next to water; so crocodiles seem to search for places where such prey may be concentrated, e.g. the water under a tree holding a flying fox colony, or spots where herds of water buffaloes feed, in order to capture small animals disturbed by ...
Sweat glands in the skin secrete a fluid waste called sweat or perspiration; however, its primary functions are temperature control and pheromone release. Therefore, its role as a part of the excretory system is minimal. Sweating also maintains the level of salt in the body. Mammals excrete sweat through sweat glands in the skin throughout the ...
The creature’s name alludes to its “strikingly” star-like appearance. The specimen found in Australia has a different coloring but similar pattern to the Japanese specimens, according to ...
