That's amazing , I have seen a similar thing, and also recently I've seen picture of a sea turtle who's lower jaw/ beek had been injured or taken clean off by a boat ( I think) and some clever people made a new lower jaw/ beek out of titanium and screwed it onto what was left of the jaw ( upper and lower) they kept him in captivity for a few weeks to make sure he could use it and then released him. It really did look bionic, amazing
