Diversity. The cephalopods are a diverse class of mollusks (a group that also includes snails and bivalves) that emerged during an explosion of animal diversity in the oceans during the Cambrian period, over 500 million years ago (mya).
Where do cephalopods come from?
Cephalopods are found in all the oceans of Earth. None of them can tolerate fresh water, but the brief squid, Lolliguncula brevis, found in Chesapeake Bay, is a notable partial exception in that it tolerates brackish water.
Do all cephalopods have 3 hearts?
Cephalopods have not one but three hearts. The central heart pumps oxygenated blood to the body, while the other two hearts are responsible solely for the gills.
