A salp or salpa is a tube-shaped, planktonic tunicate. It moves by contracting and pumping water through its gelatinous body. The salp strains the pumped water through its internal feeding filters, feeding on phytoplankton. Only the size of a peanut,  solitary salps link together in long chains and effectively vacuum up marine algae that has absorbed CO2. As such they are seen as a possible method of reducing the build up of damaging carbon dioxide. Their numbers grow when there is an increase in algae and their presence measurably reduces the level of CO2 in the water and could have a significant effect on global warming.
