Chapa Frog

Chapa Frog (Nidirana chapaensis) is an amphibian recorded for Vietnam in the project inventory. Its supporting occurrence note is “GBIF: 217 Vietnam records”. The supplied scientific name is retained because regional frog taxonomy and species boundaries can change, while similar-looking species may require calls, detailed morphology or genetic evidence for reliable separation. This profile therefore distinguishes the recorded identity and occurrence from broader biological context instead of inventing unsupported locality, size, diet or breeding details (project species data; Amphibian Species of the World taxonomy).

These frogs belong to a ranid lineage whose members use ponds, marshes, flooded fields, forest pools or slow waterways depending on species. Adults hunt small invertebrates, males advertise with species-specific calls, and eggs hatch into aquatic tadpoles. Habitat tolerance, activity and breeding season vary widely, while taxonomy has changed for several regional forms. These are broader group-level notes rather than Vietnamese field observations, so exact size, call, habitat and clutch values are omitted (general ranid context; Amphibian Species of the World).
