Description

Dermophis oaxacae is a relatively large caecilian with a reported maximum total length of 454 mm (17.9 in). It has 119–139 primary and 101–133 secondary annuli; these high counts distinguish it from all other Dermophis.[3][4] The body is somewhat robust and the head is relatively large. The mouth is subterminal. The eyes are visible through a layer of skin. Living animals have blue-black coloration.[3] The annular grooves are ventrally marked with dark pigment, in sharp contrast to the otherwise pale venter.[3][4]

Habitat and conservation

Dermophis oaxacae occurs in semi-deciduous tropical forests[1] at elevations up to 2,100 m (6,900 ft) above sea level.[3] It is a subterranean species. It is probably viviparous.[1][3]

Dermophis oaxacae is a poorly known species with few recent observations.[1][5] It is unknown to which degree deforestation is a threat to it.[1]
