Toads might want to be careful what meal they catch with their sticky, pink tongues. It could be a toxic beetle that makes them throw up … and then scurries away to tell the tale, a new study from Japan finds.
Unfortunately, toads have to learn this lesson the hard way. After nabbing these brown and black insects, known as bombardier beetles (Pheropsophus jessoensis), a toad will likely feel an explosion in its gut, indicating that the beetle has just let loose a toxic chemical cocktail, the researchers found.
