pdf 08. Embryonic External Nares in the Microhylid Elachistocleis ovalis, with a Review of Narial Development in Microhylid Tadpoles

Abstract: Microhylids have the nares closed during most of tadpole life. In the microhylid Elachistocleis ovalis the external nares initially form in late embryonic stages but the nares then close when independent feeding begins and re-open at the start of metamorphosis. Examination of other microhylid species suggests that this may be a general feature. Given the uses of the olfactory system in tadpoles (e.g. kin recognition, predator detection), closure of the system in microhylids is a curious feature which needs further investigation.
