Cranchiidae

The family Cranchiidae comprises the approximately 60 species of glass squid, also known as cockatoo squid, bathyscaphoid squid, cranch squid, or simply cranchiids. The common name "glass squid" derives from the transparent bodies of most species. Cranchiid squid occur in surface and midwater depths of open oceans around the world. Cranchiid squid spend much of their lives in partially sunlit shallow waters, where their transparency provides camouflage.

species of mollusc

Liguriella is a genus of glass squids, the genus is probably monotypic, the only species being Liguriella podophthalma. The other named species Liguriella pardus, which was described by S. Stillman Berry in 1916, is cited as a taxon inquirendum but it is suggested that there may be in fact more than one species and there are species yet to be described.

Parateuthis tunicata, the only known member of the genus Parateuthis, is the scientific name currently given to a species of squid based on a single specimen. The validity of Parateuthis and of P. tunicata is uncertain. The sole specimen was found in the Antarctic Ocean, and is held in the repository at the Museum für Naturkunde in Berlin, Germany.
