The Chinese edible frog, East Asian bullfrog, or Taiwanese frog (Hoplobatrachus rugulosus) is a species of frog in the family Dicroglossidae. It is found in Cambodia, China, Hong Kong, Laos, Macau, Malaysia, Myanmar, the Philippines, Taiwan, Thailand, and Vietnam. Its natural habitats are freshwater marshes, intermittent freshwater marshes, arable land, pasture land, rural gardens, urban areas, ponds, aquaculture ponds, open excavations, irrigated land, seasonally flooded agricultural land, and canals and ditches.[1] They breed in spring to early summer.[2]

The domesticated Thai variety and wild Chinese populations of H. rugulosus belong to two separate genetic lineages respectively.[3] Yu et al. (2015) suggest that H. rugulosus may in fact be a cryptic species complex.[3]

Description

H. rugulosus is a large, robust frog, up to 12 centimetres (4+1⁄2 inches) or more in snout-vent length.[2] Females are larger than males. They are primarily insectivores.[4]

Regional names

The Chinese edible frog is commonly referred to as 田雞 ("field chicken") or 虎皮蛙 ("tiger-skinned frog") in Mainland China, Hong Kong, Taiwan, Macau, and Chinese communities worldwide. In Filipino, they are called "palakang bukid," which means "frog of the field".

In Thailand, this species of frog known as "kob na", literally translated as "paddy field frog". In Vietnam's Thanh Hóa Province, there is a folktale about the origin of the nickname "field chicken": The Ancestor of Frogs (Tổ tiên loài ếch). It was made into a cutout animated film in 1997.

Usage

The frogs are commonly found in wet markets, seafood markets, and pet stores. In wet markets, they are usually sold per piece or per kilogram. The medium-sized frogs are sold as pets in pet stores, and the smaller variant is sold as live food for arowanas. They are widely farmed in Sichuan, China, Malaysia, and Thailand.

These frogs, though much smaller than their Western counterparts, are used by Chinese to cook frog legs and by Filipinos who cook them for adobo dishes. The frog's forelimbs and hind legs are fried in oil, while in the adobo method (in which the entire frog is utilized), they are cooked in soy sauce and vinegar.
