It's not from my part of the world, though. The Hairy Frog is an 11 cm long amphibian from Central Africa.
It is indeed a frog, but it isn't quite hairy. Amphibians don't do hair, they don't get enough of the right proteins. Also hair would get all wet and horrible all the time. It's only the males who get it and only when it's time to breed. Wet, hairy men? I don't know.
The hairs are actually more like bits of sticky-out skin, full of arteries. The purpose of them is to increase surface area so that they can absorb that much more oxygen from water. This is good for the male because he has to sit there looking after the eggs until they hatch. If something bad comes along, it's time for self defence and this is where the broken bones come in. Or rather, come out.
There are no muscles for pulling the claw back in, so it is thought that it slips back by itself when muscles are relaxed. The cuts would probably just heal over quite nicely.
In fact, it'll probably take the predators longer to recover from what they've just seen. "Geezer's barmy! Run!"
