how many different kinds of octopuses are there
Octopus The scientific name Octopoda was first coined and given as the order of octopuses in 1818 by English biologist William Elford Leach,[118] who classified them as Octopoida the previous year.[2] The Octopoda consists of around 300 known species[119] and can be divided into two suborders, the Incirrina and the Cirrina. The incirrate octopuses (the majority of species) lack the cirri and paired swimming fins of the cirrates.[32] In addition, the internal shell of incirrates is either present as a pair of stylets or absent altogether.[120]
