The leatherback sea turtle is commonly found along the Pacific Coast, especially in the waters off California.

Leatherback sea turtles are the largest of all sea turtles and can be found along the Pacific Coast, particularly in the colder waters of California. Unlike other sea turtles, leatherbacks feed primarily on jellyfish, which are abundant in the Pacific. These turtles are known for their distinctive leathery shell, unlike the hard shells of other species. While other species like green turtles and hawksbills can also be found in Pacific waters, leatherbacks are the most commonly observed in this region.
