The Most Weird Animals

Mike the Headless Chicken

Following a non-lethal decapitation, Mike the headless chicken, later nicknamed "Miracle Mike," lived for approximately 18 months. Seen here in 1945, a little over one month after the beheading.

Janus, the Two-Headed Tortoise

In 2007, visitors to the Geneva Museum of Natural History are fascinated by Janus, a two-headed Greek tortoise, on his 10th birthday. He's named after the two-headed Roman god.

The Aye-Aye Kintana

An aye-aye from Madagascar, makes his first public appearance at the Bristol zoo in April 2005. This nocturnal primate has rodent-like teeth and a long middle finger, the better to catch and devour grubs.

The Andean Condor

It's the largest flying bird in the Western hemisphere and feeds on carrion, with a particular taste for deer or cattle. Also: Get a load of the feet on this baby!

The Scorpionfish

This species of fish, most often found in tropical waters, has sharp spines coated with venomous mucus.

The California Mastiff Bat

It has a tiny body but a wingspan of over 22 inches. Also, bats in close-up totally freak us out.

The Bairds Tapir

Prehensile nose!

The 'Walking Stick'

These insects take camouflage to the next level. Other bugs in the Phasmatodea order can look like tree bark or leaves.

A Sheep With Five Legs

A two-month-old sheep with an extra limb is photographed in 2002 in Lage Zwaluwe, Netherlands. The farmer who owned the sheep said it limped slightly but did not appear to suffer from the fifth leg.

The Chinese Goose

It may look strange, but it's very productive: a female can lay 60 eggs or more during the breeding season.
