Well, this little mite has been all over the internet recently, but I couldn't resist.
Madagascar, along with a host of fascinating creatures, including lemurs (all the lemurs, they are found nowhere else) and was once home to the now extinct Elephant Bird. Madagascar also has an interesting history, and language. An amazing description of the island can be found in the introduction of Last Chance to See by Douglas Adams. One of my favourite books of all time.
David Attenborough also seems pretty fond of the chameleon:
The Brookesia micra is the smallest chameleon in the world, part of an entire family of miniature sized leaf chameleons, the Brookesia Minima group.
