Description

Bufo asper has a large and stout body. The females have a snout-vent length of 95-140 mm, while the males have a snout-vent length of 70-100 mm. The skin is covered with warts or tubercles; the name of this species derives from its rough skin texture. The head is broad and blunt, without bony crests. This toad has an ovoid parotoid gland connected to the supraorbital ridge by a supratympanic ridge. The tympanum is visible. The hands and feet are spinous. The fourth toe is the longest, and all the toes except the fourth are fully webbed. Males have nuptial pads on the base of the first finger. Bufo asper is usually dark brown, gray or black in color, with black spotting ventrally. Males have a blackish coloring on their throats (Iskandar 1998; Inger and Stuebing 2005; Inger and Bacon 1968).

Bufo asper tadpoles are small, reaching 12-15 mm before metamorphosis. The body is oval and somewhat flattened. The tail is leaf-shaped, rounded with a narrow tip. The lower lip is quite wide (Inger and Stuebing 2005), with the cuplike mouth enabling the tadpole to adhere to the bottom substrate in flowing water (Iskandar 1998). The denticle formula is II/III. Tadpole coloration is either all black or dark brown (Iskandar 1998).
