Frequent sightingsCommon Bottlenose Dolphin
Tursiops truncatus
The Common Bottlenose Dolphin is a robust dolphin characterized by its short, stocky snout and grey coloration with a paler underbelly. Highly intelligent and social, these dolphins form complex fission-fusion societies. They are found globally in temperate and tropical marine waters, and are known for their active swimming, leaps, and use of echolocation for hunting.
Frequent sightingsGalapagos Shark
Carcharhinus galapagensis
The Galapagos Shark is a large requiem shark found in tropical waters. It is recognizable by its streamlined body and distinctive fins. This shark is known for forming schools near sea mounts and is often seen in coastal and reef areas.
Frequent sightingsGiant Oceanic Manta Ray
Mobula birostris
The Giant Oceanic Manta Ray is the world's largest ray, with a disc width that can reach up to 9 meters. It is a circumglobal species found in tropical to temperate pelagic waters, often near coastlines, reefs, and in the open ocean, diving to depths of 1,000 meters. These filter feeders primarily consume zooplankton, including mesopelagic sources, and can also eat small fish. While generally solitary, they aggregate at feeding grounds and cleaning stations. The species is currently listed as Endangered due to overfishing and low reproductive rates.
Great Hammerhead Shark
Sphyrna mokarran
The great hammerhead is the largest hammerhead species, recognizable by its wide, flat head and tall, curved dorsal fin. As a migratory apex predator, it uses its unique head for enhanced sensing and pinning down prey.
Frequent sightingsHumpback Whale
Megaptera novaeangliae
The Humpback Whale (Megaptera novaeangliae) is a large baleen whale known for its distinctive body shape, long pectoral fins (up to one-third of its body length), and knobbly head. These migratory cetaceans are filter feeders, consuming krill and small schooling fish. They are also famous for their acrobatic surface behaviors like breaching and complex vocalizations, particularly the male's elaborate songs.
Frequent sightingsKiller Whale
Orcinus orca
The Killer Whale, also known as Orca, is the largest member of the dolphin family, recognizable by its distinct black and white coloration. They are apex predators with a highly diverse diet, adapting their hunting strategies to local prey availability, and are known for their complex social structures, living in stable, matrilineal family groups called pods. These intelligent marine mammals are found in all oceans, from polar regions to tropical seas, and are active both day and night.
Ocean Sunfish
Mola mola
The Ocean Sunfish is one of the heaviest known bony fish, notable for its round, flat body. It often basks on its side at the surface of the ocean and is a diurnal predator feeding primarily on jellyfish.
Frequent sightingsOceanic Whitetip Shark
Carcharhinus longimanus
The oceanic whitetip shark is a large pelagic shark recognized by its broad, rounded fins tipped in white. It inhabits tropical and subtropical open oceans and is an opportunistic predator, feeding mainly on fish, squid, and carrion.
Pelagic Thresher Shark
Alopias pelagicus
The Pelagic Thresher Shark is recognizable by its extremely long caudal fin, which can be as long as its body and is used to stun prey. It is an active, fast-swimming carnivore found in tropical and subtropical open ocean waters, often near the surface but capable of diving to considerable depths. This species exhibits ovoviviparity and is unfortunately classified as Endangered due to overfishing and slow reproductive rates.
Frequent sightingsScalloped Hammerhead Shark
Sphyrna lewini
The Scalloped Hammerhead Shark is a large, migratory shark easily recognized by the central indentation on its hammer-shaped head. These sharks are found globally in warm temperate and tropical coastal and oceanic waters, often forming large schools around seamounts and islands. They are primarily nocturnal foragers, feeding on a diverse diet of bony fishes, cephalopods, crustaceans, and smaller sharks and rays.
Frequent sightingsSilky Shark
Carcharhinus falciformis
The Silky Shark (Carcharhinus falciformis) is a large, slender requiem shark named for the smooth texture of its skin, attributed to densely packed dermal denticles. It is a highly migratory species found in warm tropical and subtropical waters worldwide, often associating with schools of tuna and oceanic fronts. These opportunistic carnivores primarily feed on bony fishes and cephalopods, exhibiting agile and fast hunting behaviors.
Frequent sightingsSilvertip Shark
Carcharhinus albimarginatus
The Silvertip Shark is a large, streamlined requiem shark identifiable by the prominent white tips and trailing margins on all its fins. It is an aggressive apex predator, often dominating other sharks during feeding, and can be found in various tropical Indo-Pacific marine habitats from the surface to considerable depths. While often solitary or in pairs, it can also form small groups or mixed-species aggregations and exhibits variable activity patterns throughout the day and night.
Sperm Whale
Physeter macrocephalus
The Sperm Whale is the largest toothed whale, easily recognized by its enormous, block-shaped head which can be up to one-third of its body length and houses the spermaceti organ. These deep-diving carnivores primarily hunt squid, including giant and colossal species, along with fish, sharks, and octopuses, often descending to extreme depths of over 3,000 meters. They exhibit a complex social structure where females and juveniles form stable, matrilineal groups, while mature males often lead solitary lives or form bachelor pods, venturing to higher latitudes outside of breeding seasons.
Frequent sightingsSpinner Dolphin
Stenella longirostris
The Spinner Dolphin (Stenella longirostris) is a small, slender dolphin renowned for its acrobatic leaps and spins out of the water. Found in tropical and subtropical oceans worldwide, they typically feed on small mesopelagic fish, squid, and shrimp at night, often diving to considerable depths. During the day, they rest and socialize in large, often fluid, schools, sometimes in shallow coastal waters.
Frequent sightingsTiger Shark
Galeocerdo cuvier
The tiger shark is a large apex predator recognized by the dark vertical stripes along its body, especially visible in juveniles. It inhabits tropical and subtropical waters and has a highly varied diet, feeding on fish, rays, turtles, seabirds, and other marine animals.
Frequent sightingsWhale Shark
Rhincodon typus
The whale shark is the largest fish in the world and a gentle filter feeder.
Frequent sightingsYellowfin Tuna
Thunnus albacares
The Yellowfin Tuna is one of the fastest and most powerful pelagic fish in the ocean. Recognizable by its sleek body and distinctive yellow fins, it inhabits tropical and subtropical waters worldwide. It often forms large schools and is frequently encountered around reefs, drop-offs and offshore seamounts, where it hunts smaller fish and squid with remarkable speed.
