Life and Death at 300 Metres

A juvenile giant Pacific octopus, Enteroctopus dofleini, pounces on a passing tanner crab, Chionoecetes bairdi. Once the crab is secured the octopus retreats and will consume its meal in the safety of its den. E. dofleini is a stealth predator that primarily eats crustaceans, other mollusks and fish. This video was captured on the Strait of Georgia webcam at 300m depth.
