The world's largest invertebrate is not a fast and voracious predator as previously thought, say scientists. The colossal squid, a creature once linked to maritime myth and feared as a sea monster, is really a slow drifting animal that ambushes unwitting prey.
That conclusion was reached by studying the physiology and feeding habits of other deep sea species and scaling up to the colossal squid's huge size. Its large size and predatory nature fuelled the ancient myth of the underwater 'kraken' seamonster and modern speculation that the colossal squid must be aggressive and fast, attributes that allow it to prey on fish and even give sperm whales a hard time.
