Photo: Hybrid "Superpredator" Invading California Ponds



A "supersize" hybrid salamander is gulping down smaller amphibians—such as Pacific chorus frogs (F, the frog in its larval stage) and California newts (E, the newt in its larval stage)—in ponds throughout California's Salinas Valley, a June 2009 study found.

The voracious hybrid (D, the largest variety, and C, the smallest) is a blend of the native California tiger salamander (A, the largest variety, and B, the smallest) and the invasive barred tiger salamander (not pictured).
