* Seals: Harbor seals, grey seals, elephant seals, and other seal species are a common food source for great whites.
* Sea lions: California sea lions and other sea lion species are also targeted by great whites.
* Whales: While less common, great whites have been known to prey on young or injured whales, including gray whales, humpback whales, and even smaller whales like dolphins.
* Other marine mammals: Occasionally, great whites may also eat sea otters, porpoises, and even sea turtles.
It's important to note that while these are the main types of mammals great whites eat, their diet can vary depending on their location and the availability of prey.
