World's Weirdest Animals

A look at some of nature's strangest species, including the Dracula-fish of northern Burma.

It is just 17 millimetres-long, transparent and has hook-shaped extensions that look like teeth protruding through the skin above its mouth. Zoologists called it one of the most "extraordinary vertebrates discovered in the last few decades".

Here's a look at some of the strangest examples of nature's wonderful variety.
