Incirrata (orIncirrina) is a suborder of the orderOctopoda. The suborder contains the classic "benthic octopuses," as well as many pelagic octopusfamilies, including thepaper nautiluses. The incirrate octopuses are distinguished from thecirrate octopuses by the absence in the former of the "cirri" filaments (found with the suckers) for which the cirrates are named, as well as by the lack of paired swimming fins on the head, and lack of a small internal shell (the "shell" ofArgonauta species is not a true shell, but a thincalcite egg case).
Note: A new unnamed white species was discovered February 26, 2016 byNOAA’sDeep Discoverer about 2.5 miles below the ocean surface near the Hawaiian Archipelago.[2]
