The world's weirdest animals.

Western tarsier

The huge eyes of this pocket-sized primate - each bigger than its brain - are surely nature's most outlandish night vision goggles, while it's huge feet and powerful back legs mean it is capable of leaping from tree to tree in search of insects and small invertebrates.

 
 Sloane's viperfish

The front end of this fish is the stuff of nightmares, with a grotesque battery of fangs protruding from its cavernous mouth like the spikes of an iron maiden. The explanation for these features lies in the fish's habitat,between 1,000 and 2,000 metres below the surface of the ocean.






  



Bald uakari

The shocking red pate of this follically-challenged simian has earned it the nickname among South Americans of 'mono angles', or 'English monkey', in honour of the first sunburnt Britons to visit their homeland.









 

Fog-basking beetle

This ordinary-looking beetle employs an extraordinary method for capturing water. Rain in its Namib Desert home is a luxury, so when coastal fog rolls inland it performs a headstand in the sand, capturing droplets of water on its back legs.





Lowland streaked tenrec
Tenrecs hail from Madagascar, home to a number of oddball species – including the Aye Aye and the Lemur. Bristling with quills and boldly decked out in yellow and brown stripes, this creature will attack would-be assailants, aiming to drive home the lethal, detachable barbs around its neck.






 

Axolotl

A type of salamander, this amphibian is the Peter Pan of the animal world. It remains in its larval stage throughout its life, which explains its feathery gills and lidless eyes. It also has remarkable healing powers. An axolotl that loses a limb will quickly grow a new one and it can even regenerate complex body parts, including parts of its brain and its spinal chord, making it of particular interest to scientists.





Babirusas

It's no wonder that the bizarre tusks of the babirusa are the stuff of legend on the Indonesian island of Sulawesi, inspiring tall tales and demonic masks among the islanders who share its home. The babirusas will sharpen the tusks against trees and use them during disputes with rivals.











 



Proboscis monkey

The Malay word for this primate is orang belanda, or 'Dutchman', its pot belly and big nose reminding locals of Borneo's first European settlers. Regardless of stereotypes, this monkey does boast one of the most comical faces in the animal kingdom.











Treehoppers
Also known as "thorn bugs", these insects are certainly adept at the art of impersonation. Some species have even more ornate, horn-like protrusions that allow them to resemble a dead leaf. If their disguise is rumbled, they spring away on powerful hind legs.
