What jellyfish can tell us about climate change http://apocadocs.com/s.pl?1237644162
Acidic ocean water has already affected sea life, from hearty sea corals to the shells of open ocean snails called pteropods, which swim on the surface. The shells of these snails are made out of calcium carbonate, which is starting to dissolve from the acid.
Hunt and his fellow researchers observed a startling cascade effect, noting that the young red paper lantern jellyfish roost in the shells of these snails. As the snails have started to wilt from acidic oceans, it has left young red paper lantern jellyfish vulnerable.
"If that snail goes, the red lantern goes. If the red lantern goes, maybe the sea spider and shrimp will go. We just don't know," Hunt said. "If we're not careful, we may well hinder some network of species that does impact us." Hunt and his fellow researchers were caught off guard by the speed with which acidic water affected creatures on the ocean surface, which, in turn, rippled thousands of feet below.
