Atlantic Fire Ascidian, Pyrosoma atlanticum
2014-01-12 00:00:00

Pyrosoma atlanticum is a species of colonial tunicate found in temperate waters worldwide, usually between 50°N and 50°S. It is most plentiful at depths below 800 feet. It is found in colonies that are pelagic and move throughout the water column. In the evening the colony will move closer to the surface and descend back by dawn. Large colonies can rise and descend more than 2,500 feet in a single day. A colony of this species is cylindrical and can grow up to 2 feet long and 2.5 inches...

Phallusia nigra

Phallusia nigra is a species of sea squirt (tunicate) found in tropical seas around the world. It is usually found in shallow waters attached to any hard substrate. It is a solitary animal rather than living in colonies. Although the native range of this animal is unknown, the tropical western Atlantic Ocean, the Red Sea and the Indian Ocean are possibilities. Like all ascidians, this species has a thick leathery envelope (tunic) containing cellulosic material. The tunic encloses a...

Sea Pork, Aplidium californicum

Sea Pork (Aplidium californicum) is a species of sea squirt (tunicate) in the Polyclinidae family. It is quite common on the west coast of North America from British Columbia to Baja California, and the Galapagos Islands. It is found in the intertidal zone and at depths down to 280 feet. This is a compound tunicate forming sheets, mounds, or slabs on rocks and other hard substrates. It is jelly-like in consistency, and is 0.4 to 1.2 inches thick. It is shiny yellow, orange, reddish-brown...

The White-spotted Sea Squirt (Pycnoclavella diminuta), also known as the White-spotted Ascidian or White-spot Ascidian, is a species of tunicate found in the Indian and West Pacific oceans, and found along Australia, Lord Howe Island, New Caledonia, Indonesia and the Philippines. It lives at depths of 16 to 66 feet in the benthic zone in caves and under ledges. It often occurs in environments with soft corals. This species lives in colonies composed of small clusters of zooids that...

A salp is a barrel-shaped, free-floating tunicate (any living organism which has a saclike body enclosed in a thick membrane or tunic with two openings or siphons for the ingress and egress of water). It moves by contracting which pumps water through its body. The salp strains the water with internal feeding filters as it goes through the body. It consumes phytoplankton that are strained from the water. Salps are common throughout equatorial, temperate, and colder seas. They are most often...
