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 snakes chose to go hungry, while the other four attempted to eat the frogs, but first dragged them across the ground to remove some of the toxins.

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