Galiteuthis phyllura

A species of glass squid, Galiteuthis phyllura, or the "cockatoo squid," can remain motionless in the water column waiting for prey by regulating the ratio of ammonium chloride to seawater it holds in a specialized internal cavity. The cockatoo squid also varies from most squid in that rather than squirting out ink, it fills its body with ink to camoflauge its internal organs, which are otherwise visible through its transparent body. © 2006 MBARI
