This frog can injure a hunter to the bone.
In Africa, scientists have found a wolverine frog that breaks its own bones to release claws and grows hair to protect its offspring.
Evolution has given the African hairy frog a unique way of defense — with a special muscle movement, it breaks the bones in its fingers and pushes them through the skin, turning them into sharp claws. When the fight is over, the tissues heal over time, and its legs become safe again.
Local hunters in Cameroon and Congo are aware of this feature and catch the frog only with a machete or spear. If grabbed by hand, it will release claws capable of cutting human skin to the bone.
However, this is not the only feature of this species. During the mating season, males grow thin, hair-like threads that grow along the sides and legs. These threads contain arteries and may help the frogs absorb more oxygen, protecting the eggs underwater.
According to scientists, the frog is not aggressive and only releases its claws when cornered. It remains a mystery to researchers how this frog manages to regenerate its tissues so quickly.
