About the Spiny Terrapin

The spiny turtle (Heosemys spinosa) is a South-East Asian turtle species. It inhabits lowland and hill rainforest, usually dwelling in the vicinity of small streams in hill areas up to 1,000 m above sea level. It is found in Brunei, Indonesia, Malaysia, Myanmar, India, the Philippines, Singapore, and Thailand.

The spiny turtle is a medium-sized tortoise with a brown shell and red-spotted head. Also known as the "cog-wheel turtle," it derives its name from its spiky-edged carapace, marginal scutes, and spiny keel. As juvenile spiny turtles become adults, the black striped and yellow underside of their shell fades in color. In addition, the juveniles' serrations, or jagged edges, at the carapace margin decrease in size and become restricted to the carapace's rear margin. These changes of the spine and carapace serve as evolutionary adaptations attempting to prevent predators from preying on juvenile turtles.

The spiny turtle belongs to the kingdom of Animalia, the order of Testudines, and the genus of Heosemys. The classification of Heosemys incorporates four species: Heosemys annandalii, Heosemys depressa, Heosemys grandis, and Heosemys spinosa; however... Wikipedia →
