Etymology
editThe specific name, gervaisii, is in honor of French zoologist Paul Gervais.[2]
Geographic range
editC. gervaisii is endemic to the Philippine Islands.[3] Its range includes the islands of Basilan, Catanduanes, Cebu, Lubang, Luzon, Mindanao, Mindoro, Negros, Panay, Polillo, and Tablas.[1]
Habitat and behavior
editC. gervaisii is found from near sea level up to altitudes of 1,000 m (3,281 ft). It lives in forests and plantations, burrowing in the leaf litter and hiding under stones and fallen logs, or between the buttresses of trees.[1]
Description
editThe longest specimen of C. gervaisii measured by Boulenger (1894) had a total length of 25.5 cm (10.0 in), which included a tail 2.0 cm (0.79 in) long.
Reproduction
editConservation status
editThe IUCN has listed C. gervaisii as being of "least concern" because it has a wide range, appears to be abundant with a stable population, and seems to be tolerant of disturbance to its natural habitat. No particular threats to this species have been identified.[1]
