The Columbia Spotted Frog, Rana luteiventris, is a North American species of frog. It is green to brown in color with spots on the dorsal surface. The belly and upper lip are white in color. Individuals can be distinguished from other Rana species by their shorter back legs, narrow snout and upturned eyes. Since they spend most of their time in the water, they also have more webbing in their hind feet than similar species. Although unthreatened, this animal has been studied as a model species for the effects of habitat fragmentation.

“But I go with my friend to the shore of our little river, and with one stroke of the paddle, I leave the village politics and personalities, yes, and the world of villages and personalities behind, and pass into a delicate realm of sunset and moonlight, too bright almost for spotted man to enter without novitiate and probation.”
—Ralph Waldo Emerson (1803–1882)
“Squats on a toad-stool under a tree
A bodiless childfull of life in the gloom,
Crying with frog voice, “What shall I be?
Poor unborn ghost, for my mother killed me
Scarcely alive in her wicked womb.”
—Thomas Lovell Beddoes (1803–1849)
