A Guide to the Amphibians
and Reptiles of California

California's Reptile and Amphibian Diversity

observation link

According to my count, as of August 2018, at least 249 forms of reptiles and amphibians can be found established in the wild in California including 73 endemics (found only in California) and 22 documented 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 species and subspecies, or with the re-classification of species and subspecies. I will keep updating this list as changes happen.
