What Can a Fish Tell You?
Photograph by Randy Olson

Once in hand, a fish—including specimens such as this Corymbophanes kaiei—can say a lot about the state of the environment, at least to a trained scientist. Ichthyologist Larry Page sees the big picture in Guyana as generally bright. “Although we encountered areas of severe stream degradation as a result of mining for gold and diamonds, the adverse effects appeared to be localized,” Page reports. “The mines do not seem to have had large impacts downstream—yet.”
