Cuttlefish, Squid and Relatives Thrive in Warming Oceans

Warming oceans are bad news for a number of marine species, but cephalopods — the many-armed mollusk group that includes octopus, squid and cuttlefish — are doing just fine. Scientists gathered data from cephalopod fisheries around the world, examining how catch rates — the number of cephalopods captured or sampled at one time — changed for 35 species between 1953 and 2013. The researchers found steady increases in diverse cephalopod populations living in a variety of oce
