Amorous Bullfrogs (Lithobates catesbeiana) in Woski Pond.   The Bullfrog is not native to Yosemite.   They are voracious predators that will eat anything they can get their mouths around including birds, amphibians, reptiles, small mammals, and are implicated in the decline or local extinction of the California Red-legged frog and the Western Pond turtle.  As a result, park biologists work to remove the bullfrog from Yosemite's warm water ponds.

  • Sierra Newt in Hetch Hetchy.  Adorable and beautiful, the newts appear in profusion after a rain and early in the morning.  They can migrate for miles and return to their breeding grounds (apparently using the earth's magnetic field).  Their bright orange colors serve as a warning signal to predators.   In fact, the newt's skin secrets a deadly neurotoxin similar to that found in pufferfish.  The only animal known to eat these amphibians are certain types of garter snakes which are fairly immune to the toxins.  However, like most amphibians around the world, Sierra Newts appear to be declining in numbers.  While the causes of decline of many species of frog and toad are well documented, the newts remain poorly studied by comparison.  Copyright © 2008 James McGrew.
