Each of the giant Pacific octopus' eight arms is lined with two rows of up to 280 suckers, giving the animal an acute sense of touch and even taste. Its arms are used as a means of locomotion and for feeding. To escape a potentially dangerous situation, an octopus can squirt out a cloud of black ink or use jet propulsion to quickly swim away. The Giant Pacific Octopus is the largest octopus in the world, growing to over 30 feet and weighing more than 100 pounds. It uses its parrot-like beek to deliver a mild venom in its saliva to paralyze prey. It may also use a file-like tongue to drill a hole in a hard-shelled animal to inject its venom. Despite being so large, its venom is not nearly as toxic as that of the much smaller blue-ringed octopus. Aquarium of the Pacific, Long Beach, CA.
