Killer whales and sharks eat sea lions. Although sea lions swim faster than both predators, killer whales and sharks are often able to surprise them before they can escape.
Young, sick or injured sea lions are easier for killer whales and sharks to catch. Healthy sea lions may be able to escape their predators by leaving the water and moving to the shore. If a sea lion does not move far enough away, however, a killer whale or shark may be able to jump high enough to catch it.
Both types of predators are eating more sea lions than ever before. In many cases, this is because humans have driven killer whales and sharks from their natural habitats. These predators are also eating more sea lions because other food sources are not as plentiful as they used to be.
