Do you hold a warm spot in your heart for these cold-blooded creatures? Lizard lovers celebrate the scaly squamates on this day each year. This camouflaged panther chameleon is one of a multitude of lizards that inhabit the island of Madagascar, many of which are found nowhere else. More than 50% of chameleon species are found only on the island, including the world"s smallest known chameleon, the recently discovered Brookesia nana, which is smaller than your fingernail.
