The spiny turtle (Heosemys spinosa) inhabits lowland and hill rainforest, usually in the vicinity of small streams. The origin of its common and specific name is immediately apparent from the sharp, pointed, spiky-edged carapace, and spiny keel, of this unique turtle, also known as the 'cog-wheel turtle'. The spiny turtle is known from Brunei, Indonesia, Malaysia, Myanmar, the Philippines, Singapore, and Thailand.
