The great white shark is arguably the world's largest-known extant macropredatory fish, and is one of the primary predators of marine mammals, such as pinnipeds and dolphins. The great white shark is also known to prey upon a variety of other animals, including fish, other sharks, and seabirds. It has only one recorded natural predator, the orca.

The fishery peaked in 1985 and 1986, when 550,000 kg (1.2 million lbs) were taken annually, making this species the number one shark fished off California.
