Leptosynapta dolabrifera, the snot sea cucumber, is a small sea cucumber under the class Holothuroidea (1), in the family Synaptidae. It is most closely related to another species in its genus of 34 species Leptosynapta known as Leptosynapta inhaerens .
Sea cucumbers can be found in great numbers on the deep seafloor, where they often make up the majority of the animal biomass. [17] At depths deeper than 8,900 m (5.5 mi), sea cucumbers comprise 90% of the total mass of the macrofauna. [18] Sea cucumbers form large herds that move across the bathygraphic features of the ocean, hunting food.
Synapta maculata, the snake sea cucumber, is a species of sea cucumber in the family Synaptidae. It is found in shallow waters in the tropical Indo-Pacific Ocean. Sometimes growing as long as 3 m (10 ft), it is one of the longest sea cucumbers in the world.
Sea cucumbers are found all over the world in both deep and shallow ocean waters and can be anything from less than an inch long to over six feet, and they have a huge variety of colors.
Synaptidae is a family of sea cucumbers that have no tube feet, tentacle ampullae, retractor muscles, respiratory trees, or cuvierian tubules. They also lack radial canals of the water-vascular system, with only the circumoral ring present. [2] Synaptids have elongated bodies, and their size varies significantly from small to quite large.
Actinopyga agassizii, commonly known as the five-toothed sea cucumber or West Indian sea cucumber, [1] is a species of sea cucumber in the family Holothuriidae. It was first described by German zoologist Emil Selenka in 1867. It is native to the Western Atlantic region, including the Gulf of Mexico and the Caribbean Sea, and is harvested for food.
The brown-ringed sea cucumber can reach about 8 inches in length and about 2 inches in width, the study said. It has an “elongated,” tube-shaped body with 20 tentacles and over 70 tube feet.
Cucumaria vegae, also known as tiny black sea cucumber or northern tar spot, is a species of sea cucumber. It was first described to science by Johan Hjalmar Théel in 1886 [1] reporting on the sea cucumber specimens brought back by the Challenger expedition. Among these was the type specimen for this species, which was collected at Bering Island.
