Octopus

The octopuses are soft-bodied eight-limbed mollusc of the order of Octopoda with over 300 recognised species and grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids.

The global species from the Western Atlantic, eastern Atlantic extends from the Mediterranean Sea and the Southern coast of England to Senegal in Africa, including the Azores, Canary Islands, and Cape Verde Islands.

An octopus who has an excellent sense of touch hunts at dusk crabs, crayfish, and bivalve molluscs (two-shelled cockles). Their suckers have receptors that enable octopus to taste what it is touching. Their soft bodies enable them to squeeze into small cracks and crevices as seen at the National Aquarium of New Zealand where an octopus squeezed out of its tank and made an eight-armed dash for a drainpipe that luckily for him led directly to the sea. When the octopus is swimming the organ that delivers blood to the organs stops beating. This exhausts the octopus, which is likely the reason they prefer to crawl than swim. The smallest octopus is 2.5cm long and weighs less than a gram but the largest octopus grows to 16 feet (5 meters) long and weighs around 110 lbs (50kg).
