Jellyfish Currents
"Ethereal jellies have been stirring up the world's waters for at least 550 million years now. ..dye revealed that much of the water pushed away is then sucked up again and sticks around as the jellies make their next stroke. This means that as they head hundreds of feet up to the surface to feed each day, they're dragging along cold, nutrient -rich waters from the ocean deep, then pulling warmer streams back down... Collectively, [John Dabiri] believes, these bits of marine life [ krill  and other tiny crustacean] could rival the force of the winds and tides in ocean circulation."
