''Stauroteuthis gilchristi'' is a species of small pelagic octopus found at great depths in the south Atlantic Ocean. It is believed to be one of a very small number of octopuses to exhibit bioluminescence, like its sister taxon ''Stauroteuthis syrtensis''. ==Description== ''Stauroteuthis gilchristi'' has a secondary web, a small mantle aperture and a vestigial, U-shaped shell supporting the fins. The arms are fringed with long cirri but these do not extend as far as the tip. There is no radula. It can be distinguished from the otherwise similar ''Stauroteuthis syrtensis'' by the larger suckers. Only a few specimens have been examined, and from these it seems that there is no sexual dimorphism. However, this may not be the case, as most specimens so far collected have been either males or immature females.〔(''Stauroteuthis gilchristi'' (Robson 1924) ) The Tree of Life Web Project.
