Sharks
Tiger Shark
Galeocerdo cuvier · Cartilaginous fish — family Galeocerdidae
A big tiger shark owns whatever piece of ocean it is in. The head is broad and blunt, the eye large and unhurried, and the animal's approach is a straight, slow line that tests your composure long before it tests anything else. On the shallow sand of the Bahamas or Fiji's arena dives, tigers glide through groups of divers with a serenity that has rewritten the species' reputation — attentive management, not luck, keeps it that way. They are turtle specialists, garbage-can opportunists, and long-distance wanderers whose tracked migrations span ocean basins.
Where and when to see one
"Resident" means most dives at that destination encounter them; "seasonal" means reliably present in the listed months; anything else is a bonus, not a plan.

Understanding them
Habitat: Reef edges, lagoons, seagrass banks, and open water; comfortable from knee-deep flats to the deep blue
Range: Circumglobal in tropical and warm temperate seas, from the Caribbean and Hawaii to the Coral Sea, Indian Ocean, and South Pacific
Behavior: Slow, curious, and supremely confident. Tigers approach divers more directly than most large sharks, often making repeated close passes with a deliberate, almost sleepy cadence that should not be mistaken for indifference. The dark bars that name the species fade with age but remain visible in good light.
Diet: The broadest menu of any reef shark — turtles, rays, fish, seabirds, carrion, and famously indigestible debris; adults are key predators of sea turtles
Size: typically around 3.5 m; documented up to 5.5 m (total length; mature females commonly reach 4 m and exceptional animals past 5 m).
How to behave around one
Dive with operators who brief tiger protocol: dark gloves optional but no dangling gear, stay grouped and low, keep 360-degree awareness, never block an approach path, and exit the water calmly and together.
Conservation
Near Threatened globally with regional depletion from target fisheries, shark-control programs, and the fin trade. Bahamian and Fijian shark tourism demonstrates the species' economic value alive.
