blythii Boulenger, 1920 Blyth's river frog (Limnonectes blythii), also known as Blyth's frog, giant Asian river frog or (ambiguously) giant frog, is a species of frog in the family Dicroglossidae found from Myanmar through western Thailand and the Malay Peninsula (Malaysia, Singapore) to Sumatra and Borneo (Indonesia).

Earlier records from Laos and Vietnam are considered misidentifications.

Large adults can weigh more than 1 kg (2.2 lb).

[3][4] These frogs inhabit streams with gravel and rocks in primary and secondary evergreen forest.

[3] The major threat to this species is collection for food, both for local consumption and for trade.
