Description
The largest species, Dermophis mexicanus, can grow to a total length of Script error: No such module "convert"., while the smallest one, Dermophis parviceps, reaches only Script error: No such module "convert".. The body has numerous folds, from 97 to 258, with considerable variations both between individuals within a species and between the species. There is a tentacle about halfway between eye and nostril. The lower jaw has only one row of teeth.[4] Living specimens are very dark purple to purple-black above and creamy white below.[1]
Based on external morphology, three groups of species can be recognized:[4]
- large caecilians with numerous secondary folds: D. mexicanus and D. oaxacae
- moderate-sized caecilians with numerous secondary folds: D. costaricense, D. glandulosus, D. gracilior
- small to moderate-sized caecilians with few secondary folds: D. occidentalis, D. parviceps
