Hairy Frog: The Wolverine Claws
Central African forests hide a creature straight from an X-Men comic. The hairy frog literally breaks its own toe bones to create defensive claws. When danger approaches, its muscle contractions force bone fragments through the skin’s surface like natural switchblades. After the threat passes, the bones retract back inside. This extreme adaptation gives the frog a fighting chance against forest predators. Local people sometimes call it the “horror frog” for obvious reasons.
