Crustaceans – Shedd Aquarium

Burly is the best way to describe the Tasmanian king crab, one of the world’s largest crab species. The female’s broad, oval carapace, or outer shell, can be larger than a football, and she can weigh 15 pounds. The male can be twice as massive! Both sexes are equipped with two claws.
