The reef squid is a medium-sized cephalopod commonly encountered on shallow coral and rocky reefs across tropical and subtropical waters. It reaches about 25 cm in length and is instantly recognisable by its flattened body, prominent fins running the full length of its mantle, and remarkable ability to change colour and pattern in seconds. These squid are highly social and often hunt in loose groups, using their speed and intelligence to pursue small fish and crustaceans. Their conspicuous behaviour and colour-changing displays make them engaging subjects for observation.
