About Pseudacris cadaverina (Cope, 1866)
Pseudacris cadaverina, commonly called the California tree frog, is a cryptically colored tree frog species that often resembles granitic stones. Its dorsal surface is grey or light brown with darker blotches, and its belly is whitish. The undersides of its legs, groin, and lower abdomen are yellow, and males of this species have a dusky-yellow throat. The California tree frog has noticeable toe webbing and toe pads, and its dorsal skin is roughened and warty. It measures 2.9–5 cm (1.1–2.0 in) from snout to vent. This species most often lives along streams with abundant boulders and cobbles in their channels. Its distribution is spotty and localized, and these frogs are easy to handle. The IUCN does not consider the California tree frog to be threatened: it is a relatively common species with a broad distribution, and there are no major threats, with the possible exception of UV radiation that reduces embryonic survival. Another potential threat to this frog species is habitat fragmentation, which could contribute to low genetic diversity across different populations.
