Californian River Dolphin

The Californian River Dolphin is a species of river dolphin that is the only known indigenous North American river dolphin, found in rivers and lakes of California, Nevada, Arizona, and Oregon. It resembles a hybrid between an Amazon river dolphin and the Indian river dolphin. It feeds on trout, salmon, perch, introduced Asian carp, bass species, and other indigenous fish species. It is about as smart as a bottlenose dolphin, as it evolved from a same ancestor.
