Columbia Spotted Frog (Rana luteiventris)

Adults: 4.4-1-cm (1.75-4in) long from snout to vent. They are larger than the Wood Frog, lack the mask and have a salmon or red color on their undersides. Have somewhat bumpy skin, relatively short hind legs and vary from light to dark brown above with a scattering of large black spots often with light centers. There is a light stripe on the upper jaw and the eyes are upturned. 

Eggs: Laid in masses of 7.5-20cm (2-8in) diameter containing 150-2000 eggs, usually in shallow water floating freely on surface among vegetation. Eggs usually deposited immediately after ice melt (mid April along the Stikine).


1. Seldom found away from permanent rivers, lakes, ponds, muskegs, or streams; often in vegetation surrounding bodies of water. Coastal forests.

2. Males call on warm, clear days from above and rarely under water. Their voice is a short series of low pitched, quiet grunts and drones.

3. Distinguished from the introduced Red-legged Frog by its shorter legs, greater tow webbing, rougher skin, upturned rather than out-turned eyes, shorter jaw stripe, and lack of mottling on the groin.

4. They have been found 100 m above the valley floor of the Stikine River in a muskeg pond.

5. They commonly overwinter underwater in mud and under stream banks!
