'Fang'tastic: Biologists report snake-like dental glands in amphibians

Utah State University biologist Edmund 'Butch' Brodie, Jr. and colleagues from São Paulo's Butantan Institute report the first known evidence of oral venom glands in amphibians. Their research, supported by the Brazilian National Council for Scientific and Technological Development, appears in the July 3, 2020, issue of iScience.

"We think of amphibians—frogs, toads and the like—as basically harmless," says 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."
