Calotes jerdoni, commonly known as the Indo-Chinese forest lizard or Jerdon's forest lizard, is a species of lizard in the family Agamidae. The species is endemic to China and South Asia.

Etymology

[edit]

The specific name, jerdoni, is in honor of British biologist Thomas C. Jerdon.[3] Common names include green forest lizard, green garden lizard, Indochinese forest lizard and Jerdon's forest lizard.

Description/Identification

[edit]
C. jerdoni

Physical structure: A compressed-bodied lizard. This species resembles Calotes maria in pholidotic (scale) and other characters except that it has 45-57 scales round the body; gular scales much larger than the ventral scales; there is an oblique curved fold covered with small granular scales in front of the shoulders; nuchal crest less prominent; the hind-limb reaches to the eye or not quite so far.[4] Dorsal and lateral scales directed upward.

Color pattern: Deep-green dorsal coloration with yellow, orange or brown spots, but in many cases can make the body into a dark brown within a few seconds.

Length: Maximum total length (including tail): 38.5 cm (15.2 in).[4] Common total length: 32 cm (13 in). Common snout-to-vent length (SVL) : 9 cm (3.5 in).

Distribution and habitat

[edit]

Bangladesh, Bhutan, China (W Yunnan, Xizang = Tibet), India (Khasi Hills in Assam & Shillong) and Myanmar.

Terrestrial & arboreal; diurnal;[4] found in many types of forested land. Prefers dense and bushy hill forest.[5] A skillful and an adept climber, it moves over trees and bushes rather swiftly. It is active during the day time.[5]

Diet

[edit]

Insectivorous; feeds largely on insects but at times bird-eggs, nestlings, and frogs too are eaten up.[5]

Reproduction

[edit]

Oviparous; breeding season begins around April when males develop bright coloration in the forebody and begin to chase females. Female digs a small hollow in soft earth and lays 11-23 eggs in it for incubation and safety.[5]

Threat to humans

[edit]

Non-venomous and completely harmless to humans.
