Endangered sea turtles such as green sea turtles, olive ridleys and leatherbacks are seen here. Las Baulas National Park, the primary nesting area for leatherbacks in the Pacific. Due to their obligate feeding nature, leatherbacks help control jellyfish populations. Dead leatherbacks that wash ashore are microecosystems while decomposing. Further north, off the Pacific coast of Canada, leatherbacks visit the beaches of British Columbia. Notably, leatherbacks employ their front (pelvic) flippers more during forward terrestrial locomotion. This location is the only mainland site where leatherbacks repeatedly return to lay eggs. Leatherbacks of note include Bazil himself, Jumble, Weft, Fury, and Cham. Leatherbacks have slightly fewer human-related threats than other sea turtle species. Leatherbacks also feed on other soft-bodied organisms, such as tunicates and cephalopods.
