Description

Dermophis occidentalis is a small-sized caecilian measuring 192–235 mm (7.6–9.3 in) in total length. It has 95–112 primary and 29–37 secondary annuli.[5] The body is slender,[2] with its length 30 to 32 times the body width.[5]). The head is narrow and light grayish tan in color. The body is dorsally lavender plumbeous, turning lighter ventrally.[2]

Habitat and conservation

Dermophis occidentalis occurs in lowland and submontane rainforests at elevations of 365–970 m (1,198–3,182 ft) above sea level. It is a subterranean species that can be found under logs and in leaf litter. It is viviparous.[1]

Dermophis occidentalis is a poorly known species. Deforestation might be a threat to it. Its range overlaps with the Corcovado National Park, among others.[1]

gollark: Oh, and there seems to be an issue storing preferences so Edge will ask you to set it up again on every login.
gollark: Even when you actually log in it's unusable for a while more because Windows spends a while using 100% CPU for no apparent reason. You can hear the NUCs VRRRRRRRRing as loudly as they can.
gollark: In the last few years, instead of the reasonably functional setup where people's stuff was stored on a big on-premise fileserver, someone clearly decided to cloud™, and now everyone's files are on OneDrive and login takes several minutes and often breaks randomly.
gollark: The policy on using computers which people are meant to sign forbids you from "creating, running, downloading or [some other verb] executable files (programs)".
