<P> The scientific name Octopoda was first coined and given as the order of octopuses in 1818 by English biologist William Elford Leach , who classified them as Octopoida the previous year . The Octopoda consists of around 300 known species 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 . In addition , the internal shell of incirrates is either present as a pair of stylets or absent altogether . </P>
