In Cameroon, some frogs are absolutely nothing like the benign variety were utilized to. If youre a predator, you sure dont want to tinker Trichobatrachus robustus– a hairy frog types that, when cornered, will reach breaking its own bones to release a covert ace up its sleeve. Puncturing right through its toes are sharp claws which the frogs use as a last line of defense. T. robustus can be rather harmful, which is why Cameroonian hunters utilize long spears and machetes to kill the frogs for food and to prevent being cut.

Alternatively, male frogs may use their claws to grab onto rocks and other surfaces and climb up on them. Hairy frogs are predators who mostly consume mollusks and bugs, like slugs and snails. However, they do not use their claws for predation.

Researchers are presently working with local preservation groups to raise awareness about the value of preserving Cameroons rain forests and the animals that call them home. They are likewise calling for more stringent regulations on the animal trade to prevent the prohibited collection and sale of frogs.

According to zoologist David Wake, at the University of California, Berkeley, this technique to defense appears to be unique in the animal kingdom, although the Otton frog (Babina subaspera) possesses a similar “spike” in its thumb.

Despite their strong nature, the Wolverine frog is dealing with conservation issues. The rapid damage of Cameroons jungles due to logging, farming, and mining is threatening the frogs habitats. In addition, the animal trade is also presenting a threat to the types survival. The animals are likewise hunted by the Bakossi individuals of Cameroon who generally think that the frogs fall from the sky and, when eaten, help childless human couples end up being fertile.

Males of T. robustus, also known as the “scary frog” or “wolverine frog”, have hair-like structures on the body and thighs during the reproducing season. These arent just hair strands– theyre in fact dermal papillae which include various blood vessels that are believed to function a bit like a fishs gills. These structures assist the frogs intake more oxygen through their skin while they nurse their brood.

No one has ever seen a horror frog retract its claws, and given that there are no muscles that could put them back inside researchers believe these are nonretractable. As soon as out, they stay out. This isnt a certainty, because amphibians can be quite unexpected. Typically, amphibians recover fairly rapidly so tissue may be restored.
