Whale Shark

Habitat: Open ocean and productive coastal waters; feeds at the surface over plankton blooms and spawning events, though tagged animals dive far below 1,000 m

Distribuição: Circumtropical in warm seas, roughly between 30°N and 35°S, with predictable coastal feeding aggregations off Australia, Mexico, the Maldives, Tanzania, Mozambique, and the Philippines

Comportamento: A slow, steady swimmer that tolerates snorkelers well when not crowded. Feeding animals track plankton at the surface, sometimes bobbing vertically to gulp concentrated prey. Most aggregation sites are dominated by juvenile males; where the giant pregnant females go remains only partly understood.

Dieta: Filter feeder — plankton, krill, fish eggs, and small baitfish strained through gill rakers while ram-feeding or vertical suction-feeding

Tamanho: normalmente cerca de 9.0 m; documentado até 18.0 m (total length; most encountered animals are 4–10 m juveniles and subadults, with reliable records approaching 18 m).

Snorkel-only at most managed sites. Keep roughly 3 m from the body and 4 m from the tail, never touch or ride, no flash close to the eye, stay out of its path, and let the operator control entries. Touching bans and distance rules are written into regulations at Ningaloo, Isla Mujeres, and Hanifaru.

Listed Endangered in 2016 after steep Indo-Pacific declines driven by fisheries and ship strikes. Well-run tourism now gives living whale sharks measurable economic value, but crowding and propeller injuries at hotspots are real concerns.
