This Idiosepiidae contains the smallest species within the Decapoda. Males in some species mature at lengths of 6 mm ML and females at 8 mm ML (Nesis, 1982/7). These cephalopods are elongate but have a rounded posterior mantle and separate fins. A unique attachment organ is present on the dorsal surface of the mantle which is used for attaching the animal to seaweed. They are found in shallow water in the Indo-West Pacific.
