What is known about the Crab-eating Frog?

Crab-eating frogs use brackish habitats; salinity studies document tadpole tolerance, but laboratory limits do not justify moving animals into seawater.

Read that fact alongside the scientific name and species source, not as proof from an unclear photograph. Populations, ages and taxonomic limits can differ; when identification is uncertain, record the broader group.

How many Indonesian records name the Crab-eating Frog?

When checked on 2026-09-23, the GBIF search returned 485 human-observation records from Indonesia under this species name for 2016–2026. That is a count of indexed records, not an estimate of population, abundance or unique individuals. Observation effort can vary by location, and the count may change as records are added or identifications revised.

Where were observations reported?

Place labels appearing in the results include Jawa Barat, Riau, Jawa Tengah. They are labels attached to records, not a complete range map or evidence that the species occurs only there. Some labels may be broad or inconsistent. Check the underlying records before using the location information for field decisions.

How can you observe the Crab-eating Frog?

Observe in place without moving eggs, tadpoles or frogs. Images of the body and habitat, together with date and calls, can help specialists assess an identification; common names do not establish handling safety. A well-documented sighting helps others check the identification without turning one encounter into a conservation-status claim.
