Wikipedia Abstract

The foothill yellow-legged frog (Rana boylii) is a small-sized 3.72–8.2 cm (1.46–3.23 in) frog from the Rana genus in the Ranidae family. This species can be found from northern Oregon, down California's west coast, and into Baja California, Mexico. Both the Columbia spotted frog and the Cascades frog, also part of the Rana genus, live in the northern regions of this frog's territory. They prefer to live in streams and rivers, and lay their eggs in masses attached to rocks underwater.
