The Indian star tortoise (Geochelone elegans) is a threatened species of tortoise found in dry areas and scrub forest in India and Sri Lanka. This species is quite popular in the exotic pet trade, which is the main reason it is endangered.
The carapace of G. elegans is very convex, with dorsal shields often forming humps; the lateral margins are nearly vertical; the posterior margin is somewhat expanded and strongly serrated. It has no nuchal scute, and the supracaudal is undivided, and curved inward in the male; the shields are strongly striated concentrically. The first vertebral scute is longer than broad, and the others are broader than long, with the third at least as broad as the corresponding costal. The plastron is large, truncated or openly notched in front, and deeply notched and bifid behind; the suture between the humerals is much longer than that between the femorals; the suture between the pectorals is very short; the axillary and inguinal sutures are rather small. The head is moderate in size, with the forehead swollen, convex, and covered with rather small and irregular shields; the beak is feebly hooked, bi- or tricuspid; the edges of the jaws are denticulated; the alveolar ridge of the upper jaw is strong. The outer-anterior face of the fore limbs have numerous unequal-sized, large, imbricate, bony, pointed tubercles; the heel has large, more or less spur-like tubercles; a group of large conical or subconical tubercles is found on the hinder side of the thigh. The carapace is black, with yellow areolae from which yellow streaks radiate; these streaks are usually narrow and very numerous. The plastron likewise has black and yellow, radiating streaks. The Indian star tortoise can grow to 10 inches long.
The patterning, although highly contrasting, is disruptive and breaks the outline of the tortoise as it sits in the shade of grass or vegetation. They are mostly herbivorous and feed on grasses, fallen fruit, flowers, and leaves of succulent plants, and will occasionally eat carrion. In captivity, however, they should never be fed meat.
