| Eggs underwater, Fresno County. | These are unlaid eggs which have spilled out of the open abdomen of a dead Sierran Treefrog that was found at the edge of a pond in Alameda County. If you don't want to see a picture of the dead frog, don't click on the thumbnail to look at the large image. | There are three types of frog eggs in this Contra Costa County pond in mid March: the large mass on top is from the California Red-legged Frog, the long strings of eggs are from the California Toad, and the small balls of eggs are from the Sierran Treefrog. © Mark Gary |
