Squids are the largest living cephalopods in terms of each of mantle length, total length, and mass, with the largest species by at least two of these measures being the colossal squidMesonychoteuthis hamiltoni. Reaching an estimated 3 m 9.
The two largest octopus species— Enteroctopus dofleini and Haliphron atlanticus —can both exceed 70 kg lband the former has a maximum total length of more than 6 m 20 ft. Cirrate finned biolumlnescence can also reach a large size, with bobtail squid bioluminescence largest captured specimen likely being a Cirrothauma magna of 1. Members of the other cephalopod groups are substantially smaller, although the largest cuttlefish can exceed 10 kg 22 lb in weight and 50 cm 1.
What follows is an overview of the present state of scientific knowledge on the maximum size of the eight extant cephalopod species six squids and two octopuses that are known or estimated to reach at least 50 kg lb in mass. Extinct taxa are considered separately at the end.
Beak of a colossal squid from the Amundsen Sea off Antarctica. Colossal squid Mesonychoteuthis hamiltoni [ edit ] Though a substantial number of colossal squid Mesonychoteuthis hamiltoni remains have been recorded Xavier et al.
McClain et al. The largest known complete specimen of the colossal squid was a mature female captured in the Ross Sea in February Once completely thawed the specimen was found to weigh kg 1, lbbut to measure only 2.
It is likely that the specimen, and particularly its tentacles, shrank considerably post mortem as a result of dehydration, having been kept in a freezer for 14 months. The fins of the Ross Sea specimen measured around 1. The arms ranged in length from 0.]
