USU Biologist Reports Amphibians with Snake-like, Venomous Dental Glands
“We think of amphibians – frogs, toads and the like -- as basically harmless,” says Edmund "Butch" Brodie, emeritus professor in USU’s Department of Biology. “We know a number of amphibians store nasty, poisonous secretions in their skin to deter predators. But to learn at least one can inflict injury from its mouth is extraordinary.”

Some are aquatic and some, like the ringed caecilian (Siphonops annulatus), studied by Brodie’s team, live in burrows of their own making.
