The spiny turtle (Heosemys spinosa) inhabits lowland and hill rainforest, usually in the vicinity of small streams, mainly in hill areas up to 900 m.

Description

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'.

Distrubution

The spiny turtle is known from Brunei, Indonesia, Malaysia, Myanmar, the Philippines, Singapore, and Thailand.

Reproduction

Mating behaviour appears to be triggered by rain; in captivity spraying males with water results in them chasing females and attempting to mount. Nothing is known of nesting behaviour in the wild. One or two, rarely three, eggs are laid per clutch, in captivity laying usually occurring in the night or early morning. Females produce up to three clutches per year. A plastron hinge develops to ease laying. Three captive incubations have succeeded with durations of 106, 110 and 145 days.
