A salp (plural salps, also known colloquially as “sea grape”) or salpa (plural salpae or salpas^[2]) is a barrel-shaped, planktonic tunicate in the family Salpidae. It moves by contracting, thereby pumping water through its gelatinous body; it is one of the most efficient examples of jet propulsion in the animal kingdom.^[3] The salp strains the pumped water through its internal feeding filters, feeding on phytoplankton.
