California Red-legged Frog Tadpoles Released Into Santa Monica Mountains

California Red-legged Frog Tadpoles Released Into Santa Monica Mountains

California red-legged frog (Rana draytonii) eggs that may have met their demise due to late winter storms in the Santa Monica mountains of Southern California were rescued and released at the tadpole stage.

The storms disrupted egg masses of California Red-legged Frog in streams and ponds in the Santa Monica Mountains. So biologists with the National Park Service collected about 600 eggs in March 2025 and brought them to the Aquarium of the Pacific. Biologists at the aquarium raised them to the tadpole stage, enhancing their chances of survival.

“We are so proud to be able to support the National Park Service in their work to help local populations of California red-legged frogs. Our partners dedicate so much time and expertise to supporting these local species, and it’s incredibly meaningful to be able to play a role in the important work that they do,” Erin Lundy, Aquarium of the Pacific manager of conservation initiatives said in a statement released by the aquarium.


The California red-legged frog was made famous by Mark Twain’s short story, “The Celebrated Jumping Frog of Calaveras County.” Listed as threatened in 1996, Rana draytonii is the largest native frog in the Western United States. It grows from 1.5 to 5 inches in length and sports an olive or brown back and reddish legs and belly. In Northern California, the frog lives alongside the San Francisco garter snake (Thamnophis sirtalis tetrataenia), which feeds on the amphibian.
