letsRept🦎 🐍 🐊 🐢

An Interface to the Reptile Database

This package was developed to facilitate the processes of reptile nomenclature update based on the Reptile Database 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!
