Description
No cranial crest; interorbital space slightly concave, a little broader than upper eyelid. Tympanum very distinct. First finger longer than second. Subarticular tubercles of toes single, no tarsal fold. Parotoids depressed, elongated to sacral region. Tarsometatarsal articulation reaching in front of eye. Dorsum smooth (Eiselt and Schmidtler 1973).

Minton (1966) found little difference between B. olivaceous and B. stomaticus, while Eiselt and Schmidtler (1973) are inclined to conside it as a subspecies of Bufo stomaticus (Eiselt and Schmidtler 1973).

Color: Uniform gray dorsum, with darkish spottings on limbs, ventrum whitish (Eiselt and Schmidtler 1973).

Bufo olivaceous is recorded from the extreme western parts of Balochistan and adjoining Iran (Eiselt and Schmidtler 1973).

Life History, Abundance, Activity, and Special Behaviors

Larva
Total length 24 - 26, tail 20 - 22 mm. Typically bufonid, with oval, bulging body and weak tail. The oral disc is typically bufonid, labial tooth row formula 2(2)/3, oral papillae are lateral (Eiselt and Schmidtler 1973).

Body is light brown, with dark specks on tail and fins, ventrum darkish white (Eiselt and Schmidtler 1973).

The tadpole feeds on algal vegetation and other concretions deposited on the surface of submerged objects (Eiselt and Schmidtler 1973).

It inhabits ponds and puddles in oasis and date palm groves in Dalbandin and Kharan, southwestern Balochistan (Eiselt and Schmidtler 1973).

Trends and Threats
Prolonged droughts, chemical pollution, pesticides (Eiselt and Schmidtler 1973).

Relation to Humans
Depends on wetlands created by agricultural activity, around salt lakes. It extends in human inhabitations, feeding on light attracted insects (Eiselt and Schmidtler 1973).

Possible reasons for amphibian decline

Prolonged drought
Drainage of habitat
Local pesticides, fertilizers, and pollutants
