Cephalopods

The Common Sydney octopus is a species found along the east coast of Australia. They possess a formidable array of defence mechanisms, ranging from hiding in the first instance, to quick bursts of speed if spotted by a predator, use of ink sacs, camouflage and even self-amputation of their limbs, a process known as autotomy. They are considered to be one of the cleverest animals found in any aquarium, and throughout scientific testing, certain species have been found to be able to identify different shapes and patterns.
