- Tiger sharks are found in the warm, tropical and subtropical waters of the east coast of North America to the east coast of Brazil. Moreover, the oceans of China, Africa, Japan, India and the Pacific also serve as their habitat.
- Tiger sharks are saltwater species that do not stay in one place. They’re often found in shallow waters, atolls and estuaries.
- The Pacific islands of Melanesia, Micronesia and Polynesia are home to the largest tiger shark population.
- Tiger sharks are one of the largest inhabitants of the ocean, though they are smaller than whale sharks and the great white shark.

- Like other sharks, tiger sharks move using fins including the pectoral fin and caudal fin, or the tail. The dorsal fin enables them to change direction. They also have vibration detectors to help them detect underwater movement.
- Some hunters amputate tiger sharks’ fins and release them again but a tiger shark without fins will certainly die because it won’t be able to swim and hunt.
- They are known as “wastebaskets of the ocean” because they will eat anything from turtles, seals, sharks, and manatee to dead whales and other marine animals. Their enormous appetite makes them eat whatever is in their path, even non-edible objects like rubber tires, license plates and beer bottles.

- Once born, pups are on their own. They have long tails which prevent them from swimming fast. In order to escape predators, including adult tiger sharks, pups use their marking to camouflage themselves with the waves.
- Females reach sexual maturity at the age of 8, while males at 7 years old.
