Salpa fusiformis, sometimes known as thecommon salp,[1] is the most widespreadspecies ofsalp. They have acosmopolitan distribution, and can be found at depths of 0 to 800 m (0 to 2,625 ft).[2] They exhibitdiel vertical migration, moving closer to the surface at night.[3][4] They can occur in very dense swarms, as solitaryzooids or as colonies. Solitary zooids usually measure 22 to 52 mm (0.87 to 2.05 in) in length. They are barrel-shaped and elongated, with a rounded front and a flat rear. Aggregate zooids are 7 to 52 mm (0.28 to 2.05 in) in length individually (excluding projections). They are usually barrel or spindle-shaped.[2]
The incursion of a large number ofSalpa fusiformis into theNorth Sea in 1920 led to a failure of the Scottish herring fishery.[5]
