"We argue that the colossal squid is not a voracious predator capable of high-speed predator-prey interactions," they wrote in an April article in the Journal of the Marine Biological Association of the United Kingdom. "It is, rather, an ambush or sit-and-float predator that uses the hooks on its arms and tentacles to ensnare prey that unwittingly approach." Tiny squid can be quick, but their metabolisms and movements slow as they get bigger or live deeper in the ocean. By the time you get 6,500 feet down like the colossal squid, the animals exist at a slow pace. And, unlike unlike warm-blooded leviathans like whales, they can. Regulating temperature has a very high energy cost, so whales have to eat a lot. Squid, by contrast, can simply hang out and wait for some fish to come by every once in a while.
