''Stauroteuthis'' is a genus of deepwater octopus, a cephalopod mollusk. This is the only genus in the family Stauroteuthidae, and only two species have been described in this genus. The organisms live below water depth; although sometimes found as deep as underwater, they generally live at a water depth of around . They do not possess a radula.〔 The stauroteuthids have the distinction of being one of the few bioluminescent octopuses; some of the muscle cells that control the suckers in most species have been replaced with photophores which are believed to fool prey by directing them towards the mouth. ==Species== * ''Stauroteuthis gilchristi'' is only known from two localities in the south Atlantic; these two localities may even represent different species.〔〔(''Stauroteuthis gilchristi'' ). Tree of Life web project.〕 * ''Stauroteuthis syrtensis'' is widespread in the North Atlantic.〔(''Stauroteuthis syrtensis'' ). Tree of Life web project.〕 The population size of ''S. syrtensis'' is unknown.〔(''Stauroteuthis syrtensis'' Verrill, 1879 ).
