What is the scientific name of Crab and Octopus?
As you have already discovered, there are actually many different kinds of crabs and octopus.





There are well over a hundred species in the Genus Octopus alone, let alone the other ten subfamilies in the Family Octopodidae, the other eight Families in Suborder Incirrina, or the three families that are in Suborder Cirrina, all of which are under the Order Octopoda and so can all be technically called octopus.





One of the most common octopus species is Octopus vulgaris (which literally means 'common octopus'). It is found world-wide, and is especially abundant in the Mediterranean, Eastern Atlantic and off the coast of Japan. They only reach about 1-3 feet in length, including the arms. These are the octopus most commonly caught by fisheries, used in lab experiments, or sold in the aquarium trade.





Crabs are even more diverse. Many of the critters we call crabs are members of the Infraorder Anomura of the Order Decapoda, Class Malacostraca, under Subphylum Crustacea of the Phylum Arthropoda. This Infraorder also includes critters we call shrimp (i.e. the mud shrimp Family Upogebiidae).





Anomura includes Families such as Coenobitidae (land hermit crabs), Diogenidae (left-handed hermit crabs), Hippidae (sand crabs), Lithodidae (stone and king crabs) and Paguridae (right-handed hermit crabs). Each of these families (and several others) all have numerous species categorized within them.





For example, Lithodidae includes species like Paralithodes camtschatica (Alaskan king crab).





Meanwhile, another Infraorder of Decapods, the Brachyura, also contains many critters we would call crabs, including Family Cancridae, the rock crabs, which includes Cancer antennarius (Pacific rock crab) and Cancer magister (dungeness crab) which are familiar eating crabs.





So the problem with providing a scientific name for the crabs is the fact that 'crab' isn't really a scientific term, since it refers to critters that aren't very closely related.
