Adults are usually 110-187mm long from snout to vent. Their olive skin is smooth, leathery, and scattered with small rounded tubercles. Behind the angle of the jaws there is at least one conspicuous white tubercle. The length of each paratoid gland is twice the paratoid width, and equal to the distance from the nostril to the tympanum. On the dorsal surfaces of the limbs there are several enlarged glands that resemble the paratoids. Above each eye curves a distinct cranial crest.
 
The glands of the toads produce a toxin that can cause intoxication in humans, and therefore is a controlled substance.
