Snakes Caught 'Wiping' Poison Off Frogs, Amidst Nature's Toxic Arms Race

Snakes Caught 'Wiping' Poison Off Frogs

In an experiment, 10 snakes from the Colombian Amazon were presented with three-striped poison dart frogs, which contain deadly toxins.

Six of the royal ground snakes preferred to go hungry, while the other four attempted to eat the frogs.

They dragged the frogs across the ground, akin to the way some birds rub toxins off their prey

This behavior was noted by biologist Valeria Ramírez Castañeda of the University of California, Berkeley, and her colleagues.
