Frequent sightingsBumphead Parrotfish
Bolbometopon muricatum
The bumphead parrotfish is the largest species of parrotfish, known for the characteristic hump on its head. They are predominantly herbivores, grazing on coral reefs by scraping off algae and live coral, and are often seen in large schools.
Frequent sightingsGiant clam
Tridacna gigas
Tridacna gigas, commonly known as the giant clam, is the largest living bivalve mollusc, capable of reaching lengths of up to 1.5 meters and weights exceeding 300 kilograms. It inhabits shallow coral reefs of the Indo-Pacific, primarily obtaining nutrients through filter-feeding plankton and from a symbiotic relationship with zooxanthellae algae in its mantle tissues. This sessile creature is diurnal, relying on sunlight for its algal symbionts, and can live for over 100 years in the wild.
Frequent sightingsGreen Sea Turtle
Chelonia mydas
The green sea turtle is a large marine reptile distinguished by its heart-shaped carapace and a single pair of prefrontal scales.
Frequent sightingsGrey Reef Shark
Carcharhinus amblyrhynchos
The Grey Reef Shark (Carcharhinus amblyrhynchos) is a medium to large-sized requiem shark, common in Indo-Pacific coral reefs and adjacent waters. Characterized by its grey body and a distinctive broad black band on the trailing edge of its caudal fin, it is a fast and agile predator. These sharks are known for their social daytime aggregations, which disperse at night for individual hunting.
Frequent sightingsHumphead Wrasse
Cheilinus undulatus
The Humphead Wrasse is one of the largest reef fish, identifiable by a prominent hump on its forehead and thick fleshy lips. It is a protogynous hermaphrodite, meaning individuals are born female and some transition to males later in life. This carnivorous species plays a crucial role in coral reef ecosystems by preying on hard-shelled invertebrates and toxic animals like the crown-of-thorns starfish.
Frequent sightingsOrange Clownfish
Amphiprion percula
The Orange Clownfish, also known as the Percula Clownfish, is a small, brightly colored reef fish found in the Indo-Pacific. It is famous for its symbiotic relationship with sea anemones, living unharmed among their stinging tentacles thanks to a protective mucus layer. These omnivorous fish feed on algae, plankton, and small crustaceans, and live in structured social groups within their host anemone.
Frequent sightingsPotato Grouper
Epinephelus tukula
The Potato Grouper is a large fish known for its spotted appearance, resembling the surface of a potato. It primarily inhabits coral reefs and is a solitary carnivore. Potato Groupers can grow to be quite large, reaching up to 2 meters in length and weighing over 100 kg.
Frequent sightingsReef Manta Ray
Mobula alfredi
The Reef Manta Ray (Mobula alfredi) is a large filter-feeding ray found in tropical and subtropical waters, primarily around coral reefs and coastal areas. Known for its pelagic lifestyle, it feeds on zooplankton and exhibits complex social behaviors, often forming aggregations at feeding or cleaning stations. This species is listed as Vulnerable due to threats from overfishing and its slow reproductive rate.
Frequent sightingsWhale Shark
Rhincodon typus
The whale shark is the largest fish in the world and a gentle filter feeder.
Frequent sightingsWhitetip Reef Shark
Triaenodon obesus
The Whitetip Reef Shark is a slender, medium-sized shark easily identified by the distinctive white tips on its dorsal and upper caudal fins. Primarily nocturnal, it spends its days resting in caves and under ledges on coral reefs and hunts at night for bony fishes, crustaceans, and cephalopods. These sharks are generally social, often found in groups during the day, but can hunt individually or cooperatively.
