The “horror frog” is not a Pokemon like the name would suggest (though it would be fairly formidable as a water type). When this amphibian feels threatened, it breaks its own bones to release claws that puncture its skin to attack its enemy. It”s quite brutal, to say the least.
People in Cameroon hunt the “horror frogs,” also known as the “hairy frogs” for the fur that grows on their legs. Their 11 inch long bodies are actually full of protein and presumably delicious.
However, the hunters have to deal with the fact that each toe on the frog contains bones inside that come to a sharp, claw-like point.
The point doesn”t become visible until the frog breaks off a bone nodule that allows the claws to shoot out of its own skin, almost like Wolverine. It only does this when it feels threatened.
This is a truly bizarre adaptation that the frogs have managed, one that scientists still have some questions about. For instance, how do the claws retract? No one knows for certain, but continuous study of these amphibians is going to be pretty tricky.
