Description
and Biology:
It is a small, slender-bodied frog. It hardly exceed 30 mm in
snout-vent length. The fingers are slender, first much shorter than
second. Toes long with slight rudiment of web.
Color:

body, extending from between eyes backward, narrowing on nape,
widening above shoulders, narrowing then widening at back, sends a
stripe to groin and another to thigh on each side.
Tadpole:
Transparent, streamlined body; head depressed, body laterally
compressed, countersunk mouth, no teeth on mouth disc. Tail long, more
than twice the length of the body, fins transparent widest at midtail.
Eyes laterally placed.
Tadpole midstream microphagus. Schools of tadpoles swim at
midstream feeding on planktonic bloom. Total length of the tadpole 78-80 mm, tail 50-52 mm.
Biology:
Microhyla ornata
is
very active. During
day
it hides under stones, logs, and
heaps of vegetation, emerging at dusk, feeds on ants and other
soft-bodied insects of small size. Breeding is
triggered by monsoons, male call is "Brrrat, Brrrat, Brrrat", outbursts
of astonishing volume considering the small size of the frog. Very small
greenish brown tiny eggs are laid embedded in gelly that floats at
surface of water.
Habitat,
Distribution
and Status:
A wide-ranging Southeast Asian
species. From Malay Peninsula, Siam, southern China, Cambodia,
Myanmar, Nepal, Kashmir, Sri Lanka, and throughout India. It has
recently shown to have wide distribution in Punjab, Pakistan (Khan,
1974, 1976, 1991a; Khan and Tasnim, 1987).
Possible
reasons for amphibian decline:
General
habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Urbanization
Prolonged drought
Habitat fragmentation
Local pesticides, fertilizers, and pollutants
Long-distance pesticides, toxins, and pollutants
Predators (natural or introduced)
