This database provides a catalogue of all living reptile species and their classification. The database covers all living snakes, lizards, turtles, amphisbaenians, tuataras, and crocodiles. Currently there are more than 10,000 species including another 2,800 subspecies (statistics). The database focuses on taxonomic data, i.e. names and synonyms, distribution and type data and literature references. There is not much other information in the database, such as ecological or behavioural information, although we are working to add such data. The database has no commercial interest and therefore depends on contributions from volunteers. Most of our data comes from published sources which is curated with help from our editors. The Scientific Advisory Board (SAB) advises us with contentious taxonomic decisions.
