Sea of Japan - List of fishes

Ctenochaetus striatus, elegantly named the "striated surgeonfish", is found in the tropical waters of the Indo-Pacific, particularly in the lagoons of La Réunion and Mauritius. In Tahiti, during the full moon, this fish displays a natural spectacle: large schools form, and after a brief moment of stillness, each individual breaks away to release eggs or sperm.

The long-spine porcupinefish is a pufferfish found in the majority of tropical and subtropical marine areas around the globe. Juveniles can be found in small groups. As they age, this species becomes more solitary. Specialized in hunting mollusks and small crustaceans, this fish exhibits a seemingly clumsy swimming behavior.

The dorsal fin of the fish, turned into suction cup allows it to cling to other animals. It sticks mostly to the body of the animal, but also in the mouth or near the gills of some "hosts" (mantas, sharks ...). it often eats its host food leftovers.

The tiger shark is the third largest shark in the world. It is recognizable by its distinctive stripes along its sides, and by its short, flat snout. Tiger sharks are opportunistic hunters, known for their "bite-and-see" exploratory behavior to assess the nutritional value of their prey. These sharks generally prefer shallow waters, but can sometimes be found at greater depths.

The checkerboard wrasse inhabits the slopes and sandy expanses of lagoons and coral reefs. Its diet primarily consists of prey with tough shells. It can be observed at depths of up to around 30 meters

Naso vlamingii, more commonly known as the bignose unicornfish, is a surgeonfish found in much of the Indo-Pacific. It has a bump above its mouth from which a blue stripe runs to the base of its eyes. It has the ability to make this stripe appear or disappear.

This fish lives camouflaged among the gorgonians. it watches its prey from a promontory and swims quickly toward them to catch them before returning to it observation post. During the breeding season, the male performs a courtship display to attract the attention of a female.

The palette surgeonfish sports a pair of venomous, erectable scalpel spines at the base of its tail, used for self-defense against predators. It primarily dwells in small groups within coastal reefs. Its electric blue color inspired the character of Dory in "Finding Nemo" and "Finding Dory".

The juveniles of this species have very long fins. They often let themselves drift with the currents in all positions, so they look like dead leaves. Adults sometimes gather in huge schools.

The blue shark, also known as the "blue skin shark," is a pelagic predator found in temperate and tropical marine waters, with occasional sightings near the coast. Its wide distribution, however, is threatened by overfishing. Recognizable by its blue back and white belly, this sleek-bodied shark mainly feeds on small fish, mollusks, cephalopods, and sometimes birds.
