Description:- Stauroteuthis syrtensis, also known as the glowing sucker octopus or bioluminescent octopus, is a species of small pelagic octopus found at great depths in the north Atlantic Ocean. It is one of a very small number of octopuses to exhibit bioluminescence. The cirrate octopuses are deep sea species that have been relatively little studied. Some have been described on the basis of a single, poorly preserved specimen, and this makes deducing their phylogenetic relationships difficult. Some authorities adopt the traditional view that the genus Stauroteuthis is part of the family Stauroteuthidae that is characterized by the presence of a secondary web. The World Register of Marine Species, however, considers that it should be placed in the family Cirroteuthidae, basing this decision on ribosomal DNA and other evidence, and that Stauroteuthidae is a synonym of this family.
