Transparent animals

They're some of the most intriguing and complex creatures on the planet but they really do have nothing to hide - because theyre totally see-through. Transparent animals - creatures with clear glass-like skin - can be found all over the world but their very existence is still shrouded in mystery.

The fascinating organisms verge on the invisible and their translucent skin often helps them elude predators. These extraordinary images were taken by a whole host of photographers from around the globe. (Caters News)
