Younger Lagoon is part of the natural range of many amphibians. Several so-called exotic species, or non-California natives, are also found here.

Amphibians are dependant on water because they must keep their skin wet in order to breathe and they enshroud their eggs in moisture in order for them to grow.  It is during the seasonal flooding that most amphibians, such as the bullfrog, the Pacific treefrog, and the endangered Red-Legged Frog are able to live near the Lagoon.  During the rest of the year they are known to live at nearby freshwater Antonelli’s Pond, and will not usually travel to the Lagoon because it is just too salty to survive.  Plus, even though you may not see these amphibians, you are very likely to hear them!
