PYROSOME (Pyrosoma atlanticum): SPECIES ACCOUNTS
SALP (Thalia democratica): SPECIES ACCOUNTS

Salps are tiny, drifting sea animals that have a clear cylindrical body with openings at each end. Between the openings is a basketlike structure covered by a sheet of mucus. The jelly-like body wall contains bands of muscle. Most salps are 0.2 to 8 inches (5 millimeters to 20 centimeters) long. Some colonies are many feet (meters) long.

Salps live in warm and cool seas.

Most salps live near the surface, but some live in deeper water.

Salps eat plant plankton, or microscopic plants drifting in water.

Salps are not considered threatened or endangered.

Salps: Thaliacea - Behavior And Reproduction

Salps swim through the water by the movement of hairlike fibers on their bodies or by contracting muscles in the body wall to draw water into their intake opening and pump it out through their water-exit opening. Although they swim, salps are at the mercy of ocean currents for their entire lives. When salps feed, water flows in through the mouth opening, through the mucus sheet covering the intern…

Salps: Thaliacea - Pyrosome (pyrosoma Atlanticum): Species Accounts

Physical characteristics: Individual pyrosomes (PYE-ruh-sohms) are about 0.3 inches (8 millimeters) long and are embedded in a thick, clear tube that forms the base for a colony as long as 24 inches (60 centimeters). Colonies are pink or yellowish pink. The mouth openings of the pyrosomes face out from the tube, and the water-exit holes point toward the inside of the colony. Pyrosomes produce ligh…
