BRASILIA: A Brazilian scientist has made the painful, first-hand discovery of the first frog capable of injecting a toxic venom into potential predators.
Carlos Jared, a researcher at Instituto Butanan in Sao Paolo, was collecting frogs in a forest Goytacazes National Reserve in southeastern Brazil when one of them head-butted him, jabbing its spines into his hand.
That caused “intense pain radiating up the arm, lasting about five hours,” Jared and several co-authors wrote in a paper published this week in the journal Current Biology.
