This package was developed to facilitate the processes of reptile nomenclature update based on a search for species synonyms according to The Reptile Databse website (Uetz et al., 2025).

Currently, the package access many species information from The Reptile Database using R interface.

I hope it to be useful, to people trying to match databases from different sources (IUCN, species traits database, etc), or trying to get summaries from a given higher taxa or region (e.g.: Snakes from Brazil). But it can also just print single species information directly in R.

Any feedback, suggestion or request are welcome!
