Onykia robusta, also known as the robust clubhook squid and often cited by the older name Moroteuthis robusta,[3][4][5][6][7] is a species of squid in the family Onychoteuthidae. Reaching a mantle length of 2 m (6.6 ft)[8] it is the largest member of its family and one of the largest of all cephalopods. The largest specimen with reliable catch data was found in the Bering Sea, a male with a total length of 3.72 m (12.2 ft) and weighing 41.73 kg (92.0 lb).[9] The tentacular clubs are slender, containing 15–18 club hooks. Arms of the species contain 50–60 suckers, and grow to 90–100% of the mantle length. It is found primarily in the boreal to Temperate Northern Pacific.
