The sandbar shark is a predator found in temperate and tropical waters of various oceans. It is characterized by its dark-colored pectoral fins and gray-blue coloration on the back. Although considered potentially dangerous to humans, attacks remain rare. This shark feeds on a variety of prey, including fish and cephalopods, and is found at depths ranging from the surface to about 100 meters.

The bicolor angelfish is a tropical fish found throughout much of the Indo-Pacific region. It is easily recognizable by its bicolor pattern, bright yellow on top, followed by blue. This omnivore frequents lagoons and protected reef slopes, either as a pair or in small scattered groups.

The coral beauty angelfish is always born female. As they grow, individuals change their sex to become male, a phenomenon known as protogynous sequential hermaphroditism. The difference between male and female is therefore visible. The adult male is larger and has an anal fin ending in a point.

Colored in fluorescent yellow, this angelfish has earned the nickname 'lemon angelfish.' All individuals are born female, and some undergo a gender change during growth. These fish, well-known among aquarium enthusiasts, are found in the western Pacific Ocean, in coral-rich tropical waters.

This fish is very shy and it is easy to approach it when diving. it eyes are hidden by transverse black lines. It has a black eyespot on the dorsal fin, which attracts the attention of predators to parts of its body where there are no vital organs.

The blacklip butterflyfish has a broad geographical distribution that spans from the Red Sea to the Galápagos Islands. Typically, it is found alone or in pairs in shallow coral reefs. It feeds on polyps of soft corals, particularly leather corals and broccoli corals.

The raccoon butterflyfish (Chaetodon lunula) is a common reef fish in the Indo-Pacific. Yellow and brown in color, it feeds on nudibranchs, algae, and corals.

The eyes of this fish are masked by a colored band, and it has an eyespot at the back of its body that attracts predators to a part of the body without vital organs. It is popular among aquarists, but it requires prey of a suitable size, preferably live.

The Mediterranean damselfish is a saltwater fish widely found in the Mediterranean Sea and the eastern Atlantic Ocean. In spring, males defend a spawning area and fan the eggs until they hatch. Juveniles are bright blue and live in small groups.

The blue-green Chromis is a fish that lives in large schools above dense coral areas. At the slightest alarm, this swift fish takes refuge in the colonies of branching corals. The Blue-green Chromis is common throughout the Indo-Pacific region.

The goldtail damselfish is a tropical fish native to the Indian Ocean and the southern tropical zone of the Pacific Ocean. Like many of its kind, this species lives in small aggregations among the branches of "stag horn" corals.

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 whitetail Dascyllus resides in the tropical waters of the Indo-Pacific region and the Red Sea. This white reef fish striped with three black bands is often found in large groups above massive colonies of staghorn corals. It feeds on zooplankton, benthic invertebrates, and algae. During the breeding season, males choose the nest and perform a dance just above it as a courtship display. The female is then invited and escorted to the nest where spawning takes place.
