They invest so much energy into spawning as many eggs as possible that they can't survive. The males however can probably mate with several females before they die so maturing earlier is an advantage. The reproductive organs in male giant squid are quite different to other smaller squid species. It's likely that giant squid's reproductive organs are adapted to store the sperm packages for a prolonged period. This may be because males rarely encounter mature females to mate with suggesting that either the sexes are separate most the time or that giant squid are solitary animals.
All squid species crush their prey into tiny pieces using their beak.
Their oesophagus runs through their circular brain so to avoid brain damage their food has to be macerated into tiny pieces. This make's identification of any prey remains very difficult. All three specimens had food remains in their stomachs. We were able to identify the prey under the microscope using the fish vertebrae and other small hard parts. This is the first time the prey of giant squid has been described for the North Atlantic.
