The frog that breaks its own bones to grow claws

What Happened

The hairy frog, found in Central Africa, deliberately breaks bones in its toes when threatened. These broken bones push through skin, creating sharp claw-like projections that defend against predators. The frog can retract the claws after danger passes, and damaged tissue heals over time. Males develop hair-like skin filaments during breeding season to increase oxygen absorption while guarding eggs underwater.
