Orange lizard with long tail (India)
This is an Oriental Garden Lizard, also known as Eastern Garden Lizard, Bloodsucker, Changeable Lizard or Crested Tree Lizard (Calotes versicolor).
Shortly after I took this photo, this lizard morphed into a greyish color to match the concrete block he was on.
Changeable Lizards are related to iguanas (which are found only in the New World). Unlike other lizards, Like chameleons, they can move each of their eyes in different directions and change color.
