Stauroteuthis

 ( Octopuses ) 

Stauroteuthis is a genus of deepwater Cirrina, a cephalopod mollusk. This is the only genus in the family Stauroteuthidae, and only three 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 which are believed to fool prey by directing them towards the mouth.
