Balloon Frog

Species : Glyphoglossus molossus
Size (snout to vent) :  5 cm

The genus Glyphoglossus comprises a group of 10 species (as of 2024) of mainly medium-sized microhylids. These frogs have broad, flattened bodies and heads, small eyes and a blunt snout. They occur in southern China and mainland and insular Southeast Asia, particularly Borneo.

Glyphoglossus molossus
(Balloon Frog, Blunt-headed Burrowing Frog) is widespread in central and southern Indochina, occurring in many lowland locales below 600 metres elevation in Myanmar, Thailand, Laos, Cambodia and Vietnam.

It naturally occurs in dry dipterocarp forest and deciduous forest. It typically lies hidden beneath loose sandy soil,  amongst leaf litter or beneath rotting logs, but it will emerge during rainstorms to congregate at seasonal pools to breed, sometimes in large numbers. The fertilised eggs float on the surface of such pools, and the tadpoles are bottom dwelling.

In some parts of its native range it is sold in wet markets for human consumption, particularly in Thailand, Laos and Cambodia. There have been attempts to farm the species, and thus localised feral populations may occur.
