Desert pupfish/Extinction status
Do pupfish have predators?
The desert pupfish does not tolerate large numbers of introduced predatory or competing fishes. Non-native species negatively affect pupfish through predation, competition, and interference with reproduction as well as habitat displacement, and disease. No other non-native fish has been observed in recent years.
What are the pupfish predators?
diving beetle
It is a close relative to the Death valley pupfish (Salt Creek pupfish) and Ash meadows pupfish. It is a tiny fish, and the male, female and juvenile can be differentiated with colors. The primary predator of these Devil hole pupfish is the diving beetle.
