Glyphoglossus molossus

Distribution and Habitat

It is found in Cambodia, Laos, Myanmar, Thailand, and Vietnam. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, moist savanna, intermittent freshwater marshes, rural gardens, temporary ponds, and heavily degraded former forest.

Breeding Biology

These large, burrowing frogs follow the general theme of microhylids that deposit aquatic eggs. There is explosive breeding activity in ephemeral water sources such as ponds and ditches. The frogs perform multiple amplectic dips to oviposit surface films of pigmented eggs. A portion of a clutch is released with each dip, with a dip lasting for about 6 seconds. 200-300 eggs are released per dip. The ova have a dark black animal pole and yellow vegetal pole. Tadpoles feed by filtering suspended material in the water column.

Status

Glyphoglossus molossus is threatened by overcatching and habitat loss.

As food

In certain areas this frog is collected in large numbers as food during the breeding season.

The Balloon Frog is very popular as a food item in Thailand, where it is known as Ueng pak khuat or Ueng phao (Thai: อึ่งปากขวด, อึ่งเพ้า). It has been traditionally considered a delicacy in Thai cuisine, the frog's texture and taste reputedly being so exquisite that it can be eaten whole. It is usually eaten barbecued as Ueng yang or Ueng ang (อึ่งยาง, อึ่งอ่าง), often wrongly labeled in English as "bubble frog" or "bullfrog" instead of Balloon Frog. Natural populations of this amphibian, however, have been severely depleted in most areas of the country owing to overcatching. Currently projects are undertaken to breed and release these frogs into their natural habitat. The first place where breeding was undertaken was in Mae Tha District, Lamphun Province in June 2011.
