The Parras characodon (Characodon garmani) is a species of goodeid fish once endemic to Coahuila, Mexico. Its natural habitats were destroyed between 1900 and 1953, and no records have been made in the last century; it is considered extinct, although the validity of this taxon and where the actual type locality is are subject to some doubt.[1] The specific name honours the American herpetologist and ichthyologist Samuel Garman (1843–1927).[2]
