Distribution
and Habitat:
Country distribution from AmphibiaWeb's database:
Pakistan, Iran, Islamic Republic of.
Bufo
olivaceous is recorded from the extreme western
parts of Balochistan and adjoining Iran. 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.
Life
History, Abundance, Activity, and Special Behaviors:
Tadpole: Typically bufonid, with oval, bulging body and
weak tail. It inhabits ponds and puddles in oasis and date
palm groves in Dalbandin and Kharan, southwestern
Balochistan. Body is light brown, with dark specks on tail
and fins, ventrum darkish white. The oral disc is
typically bufonid, labial tooth row formula 2(2)/3, oral
papillae are lateral. The tadpole feeds on algal
vegetation and other concretions deposited on the surface
of submerged objects. Total length 24-26, tail 20-22 mm.
Trends
and Threats:

Relation
to Humans:
Depends on wetlands created by agricultural activity,
around salt lakes. It extends in human inhabitations,
