The bigfin reef squid eats a variety of different marine organisms. Its main prey are usually prawns and other crustaceans, and fish. [33] Captive specimens were observed to consume one fish every 2 to 25 hours. [28] Bigfin reef squids are, in turn, preyed upon by tuna, marlin, swordfish, and other predator fish and groundfish.

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’s nerves and muscles control whether the sac is expanded or contracted. When it expands, it’s like a balloon filling up with a colored liquid. When all of the chromatophores across ...
