About Salpa fusiformis Cuvier, 1804
Salpa fusiformis Cuvier, 1804, sometimes called the common salp, is the most widely distributed species of salp. It has a cosmopolitan distribution and can be found at depths ranging from 0 to 800 m (0 to 2,625 ft). This species performs diel vertical migration, moving closer to the ocean surface at night. It can form very dense swarms, and exists as either solitary zooids or connected colonies. Solitary zooids typically measure 22 to 52 mm (0.87 to 2.05 in) in length. They are barrel-shaped and elongated, with a rounded front end and a flat rear end. Individual aggregate zooids measure 7 to 52 mm (0.28 to 2.05 in) in length when projections are excluded, and are usually barrel or spindle-shaped.
