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
edit- Stauroteuthis gilchristi (Robson, 1924): Known from two localities in the south Atlantic, and other southern ocean locations (Macquarie Island, and Kerguelen).[1][3][4]
- Stauroteuthis syrtensis Verrill, 1879: Widespread in the North Atlantic.[5] The population size of S. syrtensis is unknown.[6]
- Stauroteuthis kengrahami Verhoeff, 2023: Known from a single specimen off eastern Australia.[4]
