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 700 m (2,300 ft) water depth; although sometimes found as deep as 4 km (2.5 mi) underwater, they generally live at a water depth of around 2 km (1.2 mi).[1] They do not possess a radula.[1]
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.[2]
Species
- Stauroteuthis gilchristi is only known from two localities in the south Atlantic; these two localities may even represent different species.[1][3]
- Stauroteuthis syrtensis is widespread in the North Atlantic.[4] The population size of S. syrtensis is unknown.[5]
