They feast on phytoplankton, which are booming in our oceans due to the increase in the temperature. The phytoplankton use the Co2 to photosynthesise, taking it out of the atmosphere and then, once eaten, the CO2 gets deposited on the ocean floor in the jellyfish's poo.
Woods Hole biologists Laurence Madin and Patricia Kremer of the University of Connecticut and colleagues found that one swarm of these tiny jellyfish covered almost 40,000 square miles of the sea surface and consumed almost 74% percent ofLet's just hope those little buggers multiply and scoff to their hearts content
phytoplankton every day, removing it from the ocean and preventing it from evaporating back into the atmosphere. Instead, it was contained in their fecal pellets, which sank down into deep water at the rate of up to 4,000 tons of carbon a day.
