A rare underwater scene of Bigfin Reef Squid (Sepioteuthis lessoniana) spawning in the Pacific Ocean, Japan. Captured during the egg-laying season when squid gather in shallow waters.
Caribbean reef squid ,Sepioteuthis sepioidea, commonly called the reef squid,
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

History Under the Sea.
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.
