Titicaca Water Frog (Telmatobius culeus) is a fully aquatic species native to Lake Titicaca and the rivers that flow into it in South America. It is a member of the family Leptodactylidae, the southern frog family. The frogs are large, ranging from 3 to 5 and a half inches long.
The frog spends the majority of its life on the lake’s bottom, since it does not need to surface for air if the water is well oxygenated. Breeding happens in the shallow waters, where the female frogs lay around 500 eggs.
