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. \nTriton Bay, West Papua Province, Indonesia, 3°56'17.7941 S 134°7'10.2802 E at 1m depth

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.

The Pharaoh Cuttlefish Sepia pharaonis lives in warm water (30°C) and is fast growing. They mate and spawn at 110 days and their life span is 240 days. They lay about 1500 eggs which take 14 days to develop at 28°C. Males are larger than females and most are larger than 1 kg. \n\nIn contrary to a squid's tail fins, cuttlefish have got a fin fringe running around all of the body side. A cuttlefish moves by undulating that fringe. Additionally, the cuttlefish can use the rocket propulsion typical of all cephalopods: Water is pressed from the pallial (mantle) cavity through the hyponome or siphon (a muscular tube), which is also used to direct the propulsion. So the cuttlefish is driven backward, which it uses mainly to evade an enemy, especially on short distances. \n\nThis specimen is howering near the Lava Flow of Neira Island, Banda Sea, Indonesia \n4°30'20.418 S 129°52'57.456 E at 7m depth
