Indian star tortoise

The Indian star tortoise scientifically known as Geochelone elegans, belongs to a species of tortoise found in semi-arid grassland and scrub forest of India and Sri Lanka. The Star tortoise is a herbivorous animal and grazes primarily upon mixed grass. They also feed on opuntia (prickly pear) cactus, succulents, flowers, and weeds. Unlike other tortoise the star tortoise does not. It is one of the much sought after among exotic pets.

They are commonly found in Ceylon and peninsular India and in the areas along the westward of Sind. The star tortoise has also been spotted on the Island of Karaduva and Ramaswaran.

Anatomy and morphology

Carapace very convex, dorsal shields often forming humps; lateral margins nearly vertical; posterior margin somewhat expanded and strongly serrated; no nuchal; supracaudal undivided, incurved in the male; shields strongly striated concentrically; first vertebral longer than broad, the others broader than long, third at least as broad as the corresponding costal. Plastron large, truncated or openly notched in front, deeply notched, bifid behind; suture between the humerals much longer than that between the femorals; suture between the pectorals very short; axillary and inguinal rather small. Head moderate; forehead swollen, convex, and covered with rather small and irregular shields; beak feebly hooked, bi- or tricuspid; edge of jaws denticulated; alveolar ridge of upper jaw strong. Outer-anterior face of fore limb with numerous unequal-sized, large, imbricate, bony, pointed tubercles; heel with large, more or less spur-like tubercles; a group of large conical or subconical tubercles on the hinder side of the thigh. Carapace black, with yellow areolae from which yellow streaks radiate; these streaks usually narrow and very numerous: plastron likewise with black and yellow radiating streaks. The Indian star tortoise can grow 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.

The sexual dimorphism of adult Indian star tortoises is quite apparent. Females are considerably larger than their male counterparts. In addition, the females plastron is much flatter than that of the males which has a concave shape.
