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).
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] Their diversity is greatest near the equator (~40 species retrieved in nets at 11°N by a diversity study) and decreases towards the poles (~5 species captured at 60°N).
The adult female colossal squid has been discovered in much shallower waters, which likely implies that females spawn in shallower waters, rather than their normal depth. [3] Additionally, the colossal squid has a high possible fecundity reaching over 4.2 million oocytes which is quite unique compared to other squids in such cold waters. [42]
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 cephalopod’s right eye is small and dark, while the left eye is larger and dome-shaped. The large left eye looks upward, searching for a silhouette against the faint light above.
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.
The squid go where the small bait fish go. If there is abundant food, they will come and stay. If there is abundant food, they will come and stay. However, squid fishing as a pursuit can be ...
The largest known complete specimen of the colossal squid—and the heaviest recorded extant cephalopod—was a mature female captured in the Ross Sea in February 2007. Its weight was initially estimated at 450 kg (990 lb), its mantle length at 4 m (13 ft), and its total length at 8–10 m (26–33 ft). [ 15 ]
