The giant squid (Architeuthis dux, pictured) was for a long time thought to be the largest extant cephalopod. It is now known that the colossal squid (Mesonychoteuthis hamiltoni) attains an even greater maximum size. The giant squid seen here measured 9.24 m (30.3 ft) in total length and had a mantle length of 1.79 m (5.9 ft).
Coleoidea [1] [2] or Dibranchiata is one of the two subclasses of cephalopods containing all the various taxa popularly thought of as "soft-bodied" or "shell-less" (i.e. octopus, squid and cuttlefish).
Cephalopods are thought to be unable to live in fresh water due to multiple biochemical constraints, and in their >400 million year existence have never ventured into fully freshwater habitats. [10] Cephalopods occupy most of the depth of the ocean, from the abyssal plains to the sea surface, and have also been found in the hadal zone. [11]
Bigfin squids are a group of rarely seen cephalopods with a distinctive morphology.They are placed in the genus Magnapinna and family Magnapinnidae. [2] Although the family was described only from larval, paralarval, and juvenile specimens, numerous video observations of much larger squid with similar morphology are assumed to be adult specimens of the same family.
Northern shortfin squid is a moderately-sized squid with females ranging from 20 to 30 centimetres (7.9 to 11.8 inches) in mantle length while males are generally smaller with mantle length ranging from 18 to 27 cm (7.1 to 10.6 in). [8] Northern shortfin squid has short tentacles with a long and narrow head which is connected to the long mantle.
There are around 300 species of squid living in the ocean and they can range in size from less than an inch to the massive 50-foot-long giant squid. The strawberry squid ( Histioteuthis heteropsis ...
Bobtail squid (order Sepiolida) [1] are a group of cephalopods closely related to cuttlefish. Bobtail squid tend to have a rounder mantle than cuttlefish and have no cuttlebone. They have eight suckered arms and two tentacles and are generally quite small (typical male mantle length being between 1 and 8 cm (0.39 and 3.15 in)). [2]
The sounds of squid jigs being dropped into the water were punctuated by light conversation and the periodic sound of a squid squirting water and ink as it was reeled up from the ocean.
