The Caribbean reef squid (Sepioteuthis sepioidea) is like a living mood ring. It can transform from plain brown to translucent white to iridescent splendor, depending on whether it's courting, menacing rivals, or fleeing predators. The Cephalopod Page from marine biologist James Wood of the Bermuda Biological Station for Research profiles some 30 species, from the fickle reef squid to the Pacific giant octopus (Octopus dofleini), whose arm span can reach nearly 10 meters. Cephalopod fans can also browse more than 30 original papers on the creatures' biology.
