A closer look

Natural history & identification

Venom evidence

The database explicitly lacks species-specific venom information. Medical effects documented in other Rhabdophis must not be presented as demonstrated for this species.

Evidence & scope

Literature documented · Comment: venom evidence

Species-level database summary; literature review, not expert validation.

The cited account does not establish population-wide variation or the conditions at every Philippine locality.

Reproduction

The species account records egg-laying reproduction. A verified Philippine clutch-size range, incubation interval and breeding calendar are not established here.

Evidence & scope

Literature documented · Reproduction field

Reproductive mode reported for this named species.

Mode alone does not establish litter or clutch size, seasonal timing, or captive husbandry requirements.

Philippine distribution

The atlas records Rhabdophis auriculatus from these named Philippine areas: Mindanao, Samar, Leyte, Bohol, Basilan. These are literature areas rather than a continuous range boundary.

Evidence & scope

Literature documented · Existing checklist occurrence statement and distribution review

The original evidence level is retained.

A country listing cannot establish an island or a precise locality.

Taxonomic context

Rhabdophis auriculatus is retained in the atlas’s dated checklist under Colubridae. The authority is (GÜNTHER 1858). Earlier names and the original source notes are preserved below for comparison.

Evidence & scope

Venom classification not yet added · Effects not yet summarised in this atlas

Observe from a distance. Do not handle, corner or capture a snake to identify it. An incomplete venom account is not evidence that a species is safe to handle.

After a suspected snakebite, keep the person still and arrange urgent medical care. Avoid tight tourniquets, cutting, suction and unproven remedies. Do not wait to identify the snake before seeking help.
