Tiger sharks exist at the top of the food chain, and they prey on a wide variety of species, including fish, sea turtles and other sharks. Additionally, tiger sharks prey on sea-dwelling birds, catching them as they land on the water’s surface. Mollusks such as sea snails, conchs and whelks also serve as prey for the opportunistic sharks. Tiger sharks are also scavengers that have been known to eat garbage.Know More
According to the Shark Bay Ecosystem Research Project, tiger sharks are important in regulating the population of many of the small species that share their habitat. This includes those species that the tiger sharks hunt, as well as those that they rarely eat. This occurs because the non-prey species must still avoid the prowling tiger sharks; because of this, they cannot forage for food as often. This makes it harder for these species to grow, develop and breed successfully.
Although tiger sharks rarely attack humans, they are second to only great white sharks in terms of reported human attacks. In Hawaii, where tiger sharks are common, there is an average of one human attack each year, according to the Shark Bay Ecosystem Research Project.
While tiger sharks are apex predators, they are often caught and eaten by humans.Learn more about Sharks

The sand tiger shark is a relatively large species of shark that inhabits continental shelves and reefs to a depth of approximately 620 feet in subtropical and temperate waters worldwide. The diet of the sand tiger is composed mostly of bony fishes such as herrings, eels and bluefishes, among others. Crustaceans, squid and even smaller sharks are occasional prey.Full Answer >
Sharks are apex predators, feeding on turtles, fish, seals, crabs and mollusks. They have adapted to feed on virtually everything in their environment. Their predation is a crucial element in maintaining population in different areas of the ocean, preventing prey animals from overgrazing any one area.Full Answer >
Great white sharks grow up to 21 feet long, have a lifespan of approximately 70 years and live in all the world's oceans. In contrast, tiger sharks grow to about 16 feet, have a lifespan of approximately 50 years and are only found in temperate climates, especially around islands in the Pacific. Though somewhat visually similar, the tiger shark also has characteristic tiger-stripe markings, though these are often faded in mature adults.Full Answer >
