Deep in the Sonoran Desert are various fish species that survive in the harshest of conditions. These extremophiles often live in water that is often much saltier than seawater, much hotter than a jacuzzi, much faster than a freight train, and with little or no oxygen. Where did they come from? How do they survive? What is their future? Wes chats with desert fish expert Dr. Scott Bonar of the University of Arizona to answer these and many more questions. So, grab a tall glass of water and your sunscreen, because this one is a scorcher!   Do you have questions or comments?
