Octopus is the largest genus of octopuses, comprising more than 100 species. These species are widespread throughout the world's oceans. Many species formerly placed in the genus Octopus are now assigned to other genera within the family Octopodidae.[1][2]

The word is derived from the Greek number eight, oktō (ὀκτώ) and pous, podos (πούς, ποδός), which means feet.


The species listed above with an asterisk (*) are questionable and need further study to determine if they are valid species or synonyms.[7]
