A salp (pl.: salps, also known colloquially as “sea grape”) or salpa (pl.: salpae or salpas) is a barrel-shaped, planktonic tunicate in the family Salpidae. The salp moves by contracting its gelatinous body in order to pump water through it; it is one of the most efficient examples of jet propulsion in the animal kingdom. The salp feeds on phytoplankton, which it collects by straining water through its internal feeding filters.
