Bigfin Reef Squids are easy to distinguish from other squids in that they possess thick and muscular oval fins that extend around almost the entire mantle. Because of these fins, bigfin reef squids are sometimes mistaken for cuttlefish. The bigfin reef squid is the most widespread species in the genus Sepioteuthis. It is found in temperate and tropical regions of the Indian Ocean and the Western Pacific Ocean.\nAt night, when the Bigfin Reef Squids are most active, they are commonly found in shallow areas from 0-100m around reefs, sea grass beds, sandy bottoms, or rocky shorelines. They surface at night, as it is less likely to be detected by predators. During the day, they generally move to deeper waters or near any form of cover, such as floating driftwood, reefs, rocks, or grasses.\nSquids have speedy colour-changing abilities as their pigment cells, the chromatophores, rapidly change size and colour and the visual effect is enhanced by light reflecting cells, the iridocytes. They can shoot ink (dark melanin pigment) to confuse predators and aide in escapes. \nThis specimen was encountered in the Lembeh Strait, Indonesia\n1°28'8.916 N 125°14'39.102 E at 16m depth

A shallow coral reef with one Pharoah Cuttlefish (Sepia pharaonis) swimming alone.  These Cephalopod are able to change skin colour in an instant to blend in and camouflage with their surroundings. The animal is splaying its tentacles in defensive behavior.  Image taken whilst scuba diving in Phi Phi island archipelago, Krabi province, which is one of Thailand’s top travel destinations.  Sony mirrorless camera in underwater housing with dual Inon Z330 strobes used.
Behold the mysterious elegance of an octopus as it gracefully navigates the ocean depths, its tentacles dancing in the currents, a symbol of intelligence and adaptability.
Octopus is resting on the sand and is camouflaged to blend in with the coral. The background consists of coral and rocks.

The common cuttlefish or European common cuttlefish is one of the largest and best-known cuttlefish species. They are a migratory species that spend the summer and spring inshore for spawning and then move to depths of 100–200 metres during autumn and winter.
