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 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).
Similarly, giant squid are unlikely to naturally occur in the North Sea owing to its shallow depth [42] (but see #107 and 113, the only known English strandings). They are generally absent from equatorial and high polar latitudes [ 57 ] (but see #215 and 249 from equatorial Atlantic waters, and specimens from northern Norway [ 58 ] or #102 from ...
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]
It is a squid in the family Gonatidae, found most commonly in the northern Pacific Ocean from Japan to California. They are one of the most abundant cephalopods off the coast of California, mostly found at deeper depths, rising during the day most likely to feed. The mantle size of G. onyx has been known to reach up to 18 cm (7.1 in).
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.
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]
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 ...
