Idaho has just a handful of sharks, all in captivity, in the Aquarium of Boise in Boise City. The East Idaho Aquarium in the Idaho Falls area also has a few small shark species. The extinct Helicoprion or the buzzsaw shark had made its presence felt in several US states, Idaho being one of them. It had swum along the waters of the area presently known as Eastern Idaho. Miners also detected the fossils of the shark’s jaw, teeth, and skin in the Soda Springs area in 1950. The Idaho Museum of Natural History houses fossils of this unique shark species.
