A Guide to the Amphibians
and Reptiles of California

California's Reptile and Amphibian Diversity

observation link

According to my count, as of April 2024, at least 256 forms of reptiles and amphibians can be found established in the wild in California including 76 endemics (found only in California) and 26 documented established alien species. 4 Species once present are now considered extinct in the state.

"Forms" includes subspecies.
(If a species is divided into several subspecies and 3 subspecies are found in California, then that counts as 3 forms.)

(Go here to see a list of currently undescribed herps and some that could occur in California.)

Taxonomy is always changing so these totals will continually change with the discovery of new natrive or alien species and subspecies, or with the re-classification of species and subspecies. I will keep updating this list as changes happen.
