Squid giant axon diameters do not necessarily correlate with overall body size; those of the giant squid (Architeuthis dux) are only 0.137–0.21 mm (0.0054–0.0083 in) thick. [ 173 ] Diagram showing the three major elements (red, green, and yellow) of the squid giant neuronal system.

Taningia danae, the Dana octopus squid, is a species of squid in the family Octopoteuthidae. It is one of the largest known squid species, reaching a mantle length of 1.7 m (5.6 ft) [3] and total length of 2.3 m (7.5 ft). [4] The largest known specimen, a mature female, weighed 161.4 kg (356 lb). [5]
An octopus (pl.: octopuses or octopodes [a]) is a soft-bodied, eight-limbed mollusc of the order Octopoda (/ ɒ k ˈ t ɒ p ə d ə /, ok-TOP-ə-də [3]).The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids.
The giant squid is widespread, occurring in all of the world's oceans. It is usually found near continental and island slopes from the North Atlantic Ocean, especially Newfoundland, Norway, the northern British Isles, Spain and the oceanic islands of the Azores and Madeira, to the South Atlantic around southern Africa, the North Pacific around Japan, and the southwestern Pacific around New ...
The ink can be ejected to create a "smoke screen" to hide the cuttlefish's escape, or it can be released as a pseudomorph of similar size to the cuttlefish, acting as a decoy while the cuttlefish swims away. [32] Human use of this substance is wide-ranged. A common use is in cooking with squid ink to darken and flavor rice and pasta.
Size comparison with a human. Unlike most squid species, the colossal squid exhibits abyssal gigantism, as it is the heaviest living invertebrate species, reaching weights up to 495 kg (1,091 lb). [3] For comparison, squids typically have a mantle length of about 30 cm (12 in) and weigh about 100–200 g (3 + 1 ⁄ 2 –7 oz). [10]
