Sydney Octopus

Sydney Octopus

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 autonomy. 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.

Red Cuttlefish

Mourning Cuttlefish

When courting, the male cuttlefish will display both male and female colours simultaneously to cleverly seduce the female while at the same time hoodwinking rival males. The deceptive male positions himself between the female and the rival male. Showing his true male colours towards the female to woo her, he will at the same time mimic female colours to the rival male to disguise the courtship.



Deep within the Jurassic Seas zone at SEA LIFE Sydney Aquarium lays the mysterious nautilus, a species of cephalopod who is closely related to the squid, octopus and cuttlefish. The first nautilus appeared over 500 million years ago and today’s creatures have little variation to their ancestors, and therefore, are often described as living fossils. Nautilus has the extraordinary ability to use jet propulsion to move quickly away from its predators through the use of its internal chamber system.
