"Sepiola birostrata is one of two species of cuttlefish resident in the northern Sea of Japan. During the day, it hides on the sandy bottom and can be found only by chance. But at night it goes hunting. Despite their small size [around an inch], these cuttlefish are predators, catching shrimps and crabs. There are usually a lot of them in July, above the sandy bottom, at depths from 15 to 40 feet. I managed to meet this beauty during a night dive. Its color was simply gorgeous."
