Toad

( Incilius alvarius )

Adults are usually large, stout-bodied toads, 110-187 mm long from snout to vent. Their olive skin is smooth, leathery, and scattered with small rounded tubercles often set in rust colored spots. 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.
