The White-lipped Frog, Leptodactylus albilabris can only be found in Puerto Rico and the U.S. and the British Virgin Islands. The White-lipped Frog is a terrestrial smooth-bodied frog which passes through a tadpole stage. The tadpoles are brown colored, reaching about 1.5 inches in length.

L. albilabris can be recognized by its white upper lip, webless fingers, and toes, black streak between the eyes and the tip of the snout and between eye and shoulder. In general, adults grow to 1.4 inches in snout-vent length, but like other Puerto Rican frogs, the body size increases with elevation and adults of a snout-vent length greater than 2.0 inches are not rare in the higher regions of the El Yunque National Forest. Individuals have a grayish brown background color with dorsal lines and bands of various shades of brown, cream, and reddish brown. It is white ventrally, and some males have many dark spots on the throat. Its voice is a "pink-pink-pink" sound usually heard from a muddy area.

This frog's diet includes insects, millipedes, and land snails. It lays terrestrial eggs, but they are laid in a foam nest on the ground, usually under a rock or log. Eggs develop into tadpoles, which are washed away by the first rains and finish their development in temporary pools, or bodies of water with low or no water movement. This frog can usually be found in muddy areas near streams, marshes, and ditches.
