There are about 60 different species of glass squid and it’s also known as cockatoo squid, cranchiid, cranch squid or bathyscaphoid squid. They live in depths of open oceans around the world. The length of the glass squid is 10 cm to 3 m. The most species are transparent. This transparency keeps them hidden from predators.
Glass squid spend much of their lives in partially sunlit shallow waters. Many species are bioluminescent organisms and possess light organs on the undersides of their eyes. Glass squid represent no interest to commercial fisheries.
