29-3-2025 LEOPARD TRAILS LODGE, SRILANKA - ORIENTAL GARDEN LIZARD ( Calotes versicolor)

The oriental garden lizard (Calotes versicolor), also called the eastern garden lizard, Indian garden lizard, common garden lizard, bloodsucker or changeable lizard, is an agamid lizard found widely distributed in Indo-Malaya. It has also been introduced in many other parts of the world.

During the breeding season, the male's head and shoulders turns bright orange to crimson and his throat black. Males also turn red-headed after a successful battle with rivals. Both males and females have a crest from the head to nearly the tail, hence their other common name, "crested tree lizard".

Unlike some other lizards, they do not drop their tails (autotomy), and their tails can be very long, stiff and pointy. Like other reptiles, they shed their skins. Like chameleons, changeable lizards can move each of their eyes in different directions.

The native range of the species includes southeastern Iran, Afghanistan, Bangladesh, Bhutan, Cambodia, India (including the Andaman Islands), Indonesia (Sumatra), Malaysia (western), Maldives, Mauritius (Reunion, Rodrigues), Myanmar, Nepal, Pakistan, Philippines, Sri Lanka (Ceylon), Thailand, Vietnam (including Pulo Condore Island). It has been introduced to Brunei, Celebes, Oman, Seychelles, Singapore and United States. The lizards were introduced to Singapore from Malaysia and Thailand in the 1980s. In Singapore, they are a threat to the native green-crested lizard.[4] The changeable lizard is relatively common and found in a wide range of habitats. They appear to adapt well to humans and are thus not endangered. They are commonly found among undergrowth, in open habitats as well as highly urban areas. However, in China people regularly kill them, as they are viewed as pests.

Changeable lizards eat mainly insects such as crickets, grasshoppers, and ants; as well as small vertebrates, including rodents and other lizards including common house geckos and day geckos.[citation needed] They have teeth which are designed for gripping prey and not tearing, and thus they usually shake prey to stun it then swallow it whole. Sometimes, young, inexperienced changeable lizards may choke on prey that is too large. Changeable lizards also occasionally consume vegetable matter.
