Stellar sea lion pups experience increased mortality from predators. Transient killer whales are the most important factor in this increase.

Sea lions are large animals, the largest of which reach up to 770 pounds in weight. The killer whale's caloric needs indicate that they must eat two or three sea lions pups per day, or a single adult sea lion every few days. Human poaching is another problem for sea lions. Many fishermen shoot the sea lions, mistakenly believing that they are affecting salmon populations. However, according to Sea World Parks & Entertainment, while they do eat some salmon, sea lions also benefit salmon populations by eating some of their parasites.
