HOW did the monstrous giant squid — reaching school-bus size, with eyes as big as dinner plates and tentacles that can snatch prey 10 yards away — get so scarily big?. The camera took over 500 photos before the squid managed to break free after four hours. The largest toothed predator or the largest toothed whale has one name and that is the Sperm Whale. The photographs showed an aggressive hunting pattern by the baited squid, leading to it impaling a tentacle on the bait ball's hooks. The scientists, who were led by the University of Copenhagen's Rute da Fonseca, discovered that the giant squid's genome is 90 percent the size of our own with a whopping 2.7 billion DNA base pairs. This suggests that there is but a single species of giant squid in the world. Giant squids express sexual dimorphism. It seems the species has a much more aggressive feeding technique. So a giant squid will be longer than Colossal squid but not heavier. As it turns out, the largest known giant squid was about 40 feet long — not 60.
