What is the biggest species of squid?
Colossal squid
The colossal squid (Mesonychoteuthis hamiltoni, from Greek mesos (middle), onycho (claw, nail), and teuthis (squid)), sometimes called the Antarctic squid or giant cranch squid, is believed to be the largest squid species in terms of mass. It is the only known member of the genus Mesonychoteuthis. It is known from only a few specimens, and current estimates put its maximum size at 12–14m (39–46ft) long and weighing possibly up to 750 kilograms (1,650lb),[3][4] based on analysis of smaller and immature specimens, making it the largest-known invertebrate.
Enoploteuthidae
The Enoploteuthidea are a family of squid comprising approximately 40 species in four genera. Most species have a mantle length ranging from 3–13 cm. Hooks are present on all arms and tentacles. The family is best known for the large array of photophores throughout the body.The species listed above with an asterisk (*) is questionable and needs further study to determine if it is a valid species or a synonym. The question mark (?) indicates questionable placement within the genus.
