The Southern Rock Lobster (Jasus edwarsii) is one of the most important predators on southern reefs, growing to more than 8kg in unfished areas. As omnivores, rock lobsters do not depend directly on seaweed for food; however their diet is comprised of other animals that live in and among kelp beds. The rock lobster is the only animal on Tasmanian reefs that feeds on the invasive long-spined sea urchin (pictured in crevice). Stocks of large rock lobsters are severely depleted in Tasmania as a result of the large commercial and recreational fishery for this species. Governor Island Marine Reserve, Tasmania.
