Asian Forest Tortoise ("Manouria emys") is a species of tortoise found in India (Assam), Bangladesh, Burma (or Myanmar), Thailand, Malaysia and Indonesia (Sumatra, Borneo).

Description

The largest tortoise in mainland Asia; large adult of the northern subspecies, M.e. phayrei, can reach 25 kg in the wild and much more than that in captivity. Shell considerably depressed, its depth not half its length; anterior and posterior margins reverted, more or less strongly serrated; nuchal present; supracaudal shields two; dorsal shields concentrically striated, often concave; vertebrals much broader than long and at least as broad as costals. Plastron large, gular region somewhat produced and usually notched, hind lobe deeply notched; the pectoral shields may be widely separated from each other, or from a short median suture; axillary shield very small, inguinal large. Head moderate; two large prefrontal shields and a large frontal; beak not hooked; jaws feebly denticulated, the alveolar surface of the upper jaw with a strong median ridge. Fore limb anteriorly with very large, bony, pointed, imbricate tubercles, forming four or five longitudinal series; hind limb with very large bony tubercles on the plantar surface, with others larger, conical, and spur-like on the heel, and a group of still larger conical tubercles on each side on the back of the thighs. Adult dark brown or blackish; carapace of young yellowish brown, with dark-brown markings.

Believed to be among the most primitive of living tortoises, based on molecular and morphological studies. This is the only tortoise which lays its eggs above ground in a nest, which the female constructs of leaf litter. The female uses both front and rear legs to gather material for the nest and lays up to 50 eggs deep inside it. She then sits on and near the nest to protect it, and will 'chase' predators and intruders away. [Boulenger, G.A.(1890) "Fauna of British India. Reptilia and Batrachia."]
