Liocranchia is a genus of glass squid from the family Cranchiidae. They are moderate-sized with a long, spindle-shaped mantle which tapers to a point at the rear and they can attain mantle lengths of 250 mm. The species in Liocranchia have a cosmopolitan distribution in tropical and subtropical oceans although it has been suggested that on especies, Liocranchia reinhardti is associated with land masses. In seas off Hawaii waters L. reinhardti undergoes vertical migrations while occurs in deep water is sedentary. They are eaten by many oceanic predator species.
