THE ICHTHYOPHIS KOHTAOENSIS

There are actually a number of legless amphibians, but some of the strangest ones have tentacles sprouting from their heads. They’re known as caecilians, and some of them have some really unusual physical adaptations for a number of functions (the Mexican Walking Fish at the top of this post is just one). One caecilian has a protruding tail-like limb that enables external fertilization, for example. Though they look like soft worms, they have rows of very sharp teeth. There are over 120 species of caecilians around the world that have been discovered so far, but many of them are endangered and we don’t know much about them.
