The largemouth fish Neoclinus blanchardi lives mainly on the seabed in the northeastern Pacific Ocean. They live at depths of 5 – 70m, coastal areas and choose crevices on the ocean floor and abandoned seashells for shelter.

This special fish can open its mouth four times its size when closed. They use kissing to “fight” instead of showing affection. Male fish use their huge, powerful mouths to intimidate opponents in territorial fights.

In fact, these fish do not try to hurt each other, but with their sharp teeth, they can still hurt their opponents.

But this wide mouth prevents them from creating the necessary suction force to pull plankton towards their mouth, making it difficult to feed. Therefore, largemouth fish have to hunt small fish or eat squid eggs.

Neoclinus blanchardi fish are quite ‘powerful’, considered an “interesting hand” of the ocean because they are not afraid of anything, including humans. If you get close to a largemouth fish’s shelter on the ocean floor, be careful because they can suddenly rush out to attack you to protect their territory.

Neoclinus blanchardi fish is a smooth-skinned fish with fins running from its head to the end of its tail. The lifespan of this “alien” fish is quite short, only living about 5-6 years. Female Neoclinus blanchardi fish usually lay from January to the end of August every year with about 3,000 eggs each.
