Neon flying squid

Marine cephalopod mollusc with mantle muscular, robust, not drawn out posteriorly into a pointed tail. Fins muscular, length 40 to 45% of mantle length, width about 60% of mantle length, single fin angle 45° to 50°. A long golden or silvery stripe along the ventral midline from mantle opening to level of fin-insertion (this stripe probably is a luminescent organ); similar golden tissue on ventral surfaces of head and ventral arms (IV); numerous closely-packed, small, very irregularly shaped, often interconnected, light organs embedded under the skin in muscle of mantle ventrally; similar light organs occur in patches on ventral surface to head. Four to six small suckers on the tentacular stalk proximal to the first smooth knob of the fixing apparatus. Maximum mantle length 50 cm.
