Cryptoteuthis brevibracchiata, the short-arm flapjack octopod, is a deepwater species of octopod. It is the only species in the monotypic genus Cryptoteuthis one of the cirrate octopuses of the family Grimpoteuthidae, the umbrella octopuses. It is known from a single specimen which was collected in the northeastern Atlantic Ocean. It has characteristics which are shared with two other genera, Opisthoteuthis and Grimpoteuthis, but is sufficiently distinctive from either of these to warrant the erection of a new genus.

The octopus has been found 270–540 m (885.8–1,771.7 ft) deep. It lives near and directly above the seafloor. S. Stillman Berry was the first to scientifically describe this species after capturing eight specimens while aboard the F.I.S. Endeavour in the early 1910s. In describing O. persephone, Berry called it an "exceedingly interesting octopod".

It occupies the benthic zone, or the seafloor and the water directly above it. O. robsoni eats large amphipods.
