I never ever heard of the blind cave salamanders of Slovenia, called olms, until I read this article. They're also called baby dragons. But now I'm hoping that the eggs described in the article survive to hatch successfully.
I learned a lot quickly - they are in the genus Proteus, and there aren't any other animals in that genus. And they are only found in a few select caves in Slovenia.
So here's the articles, first found via Twitter, then in the inimitable Daily Mail. The latter is better illustrated.
