CLASS ACTINOPTERYGII (bony fishes) 
Undetermined 
Records: Calaveras Co.: *Keith’s Chasm; *Yother’s Water Cave. Fresno Co.: *Black Lake Cave (dead); *Hidden Pond 
Cave; *Millerton Lake Cave System. Imperial Co.: *artesian well near Fri nk siding, between Hecca and Niland. Mariposa 
Co.: *Bower Cave. San Bernardino Co.: * artesian well near Kokoweef Peak. Santa Clara Co.: artesian well at Santa 
Clara University. Tuolumne Co.: *McLean’s Cave. 
Comment: Apparently Yother’s Water Cave is separated from O’Neil Creek by only a ledge-like entrance, so fishes from 
the creek presumably could be found in the cave. “Sightless fishes” were reportedly discharged from a 52-m deep artesian 
well on the campus of Santa Clara University, but no verification has ever been established. The only blind fishes known 
from California are the marine gobiids, Lethops connectens Hubbs and Typhlogobius californensis Steindachner. These two 
species are found in coastal rock crevices and crustacean burrows.

Family Salmonidae (salmon, trout) 
Undetermined 
Records: Fresno Co.: *Hidden Pond Cave. Mariposa Co.: *Bower Cave. Shasta Co.: *Shasta Lake Caverns. Unknown 
Co.: Natural Bridge Cave. 
Comment: Trout were reportedly introduced into Bower Cave at one time. Trout introduced into Shasta Lake Caverns did 
not survive. There are four natural bridge caves in Calaveras and Trinity counties with potential freshwater habitat.
