Incirrina or Incirrata is a suborder of the order Octopoda. The suborder contains the classic "benthic octopuses," as well as many pelagic octopus families, including the paper nautiluses. The incirrate octopuses are distinguished from the cirrate 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" of Argonauta species is not a true shell, but a thin calcite egg case).
Note: A new unnamed white species was discovered February 26, 2016 by NOAA’s Deep Discoverer about 2.5 miles below the ocean surface near the Hawaiian Archipelago.
