$Bigfin Reef Squids are easy to distinguish from other squids in that they possess thick and muscular oval fins that extend around almost the entire mantle. Because of these fins, bigfin reef squids are sometimes mistaken for cuttlefish. The bigfin reef squid is the most widespread species in the genus Sepioteuthis. It is found in temperate and tropical regions of the Indian Ocean and the Western Pacific Ocean.\nAt night, when the Bigfin Reef Squids are most active, they are commonly found in shallow areas from 0-100m around reefs, sea grass beds, sandy bottoms, or rocky shorelines. They surface at night, as it is less likely to be detected by predators. During the day, they generally move to deeper waters or near any form of cover, such as floating driftwood, reefs, rocks, or grasses.\nSquids have speedy colour-changing abilities as their pigment cells, the chromatophores, rapidly change size and colour and the visual effect is enhanced by light reflecting cells, the iridocytes. They can shoot ink (dark melanin pigment) to confuse predators and aide in escapes. \nTriton Bay, West Papua Province, Indonesia, 3°56'17.7941 S 134°7'10.2802 E at 1m depth$

Cuttlefish or cuttles are marine molluscs of the order Sepiida. They belong to the class Cephalopoda, which also includes squid, octopuses, and nautiluses. Cuttlefish have a unique internal shell, the cuttlebone.

Coconut Octopus (Amphioctopus marginatus) is a species of benthic cephalopod that belongs to the family Octopodidae. They are known for their high level of intelligence and ability to use tools, such as coconut shells, as shelter. They are native to tropical marine environments, particularly coral reefs, and are well-known for their excellent camouflage abilities, including color-changing and mimicry. They have eight arms, each lined with two rows of suction cups, and are able to communicate with other octopuses through color changes and body language. They use jet propulsion to move through the water and can also expel ink as a defense mechanism. Overall, Coconut Octopuses are fascinating invertebrates with complex behavior and unique adaptations.
