The family Onychoteuthidae (Hooked squid) currently comprises approximately 20–25 species (several known from only single life stages and thus unconfirmed), in 6 or 7 genera. They range in mature mantle length from 7 cm to a suggested length of 2 m for the largest member, the Robust Clubhook Squid (Onykia robusta). The family is characterised by the presence of hooks only on the tentacular clubs, simple straight mantle-funnel-locking apparatus, and a 'step' inside the jaw angle of the lower beak. With the exception of the Arctic Ocean, the family is found worldwide.
