Description
Adults are 45 to 76 mm in length, with a dorsal ground color olive brown to green. The dorsal surface is mottled or spotted with dark brown and the venter is yellowish white. The skin is smooth, and may produce a mink-like odor when rubbed. Dorsolateral folds are often absent or weakly developed, toes are broadly webbed, and only the tip of the penultimate fourth toe phalanx is free of the web.
The larva reaches a total length of 100 mm. It has an olive brown or greenish dorsum with small dark spots, a straw yellow, opaque belly, mottling on the sides, and a tail which is paler than the dorsum and marked with irregular dark blotches.
