A closer look

Natural history & identification

Appearance & identification

The diagnosis gives 27–31 scale rows at midbody and a mottled underside. Other Cerberus species in the comparison have fewer midbody rows.

Evidence & scope

Literature documented · Diagnosis

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.

Ecology & habitat

The account associates this water snake with freshwater Lake Buhi on Luzon. Its restricted documented setting should not be taken as proof that every neighbouring freshwater system has been surveyed.

Evidence & scope

Literature documented · Comment: Habitat

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 live-bearing reproduction, using the term ovoviviparous. A verified Philippine litter-size range and reproductive 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 Cerberus microlepis from these named Philippine areas: Luzon. 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

Cerberus microlepis is retained in the atlas’s dated checklist under Homalopsidae. The authority is BOULENGER 1896. Earlier names and the original source notes are preserved below for comparison.

Evidence & scope

Literature documented · Checklist identity and nomenclatural trail

Checklist verified 2026-09-05; not a newly revised taxonomic backbone.

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.

Taxonomic and source notes

Habitat: This is a freshwater species. ALFARO et al. (2004) suggest that C. microlepis may prove to be an isolated freshwater ecotype of C. rynchops rather than a separate species. Lake Buhi, the type locality and only known locality of the species was formed in 1641 by an earthquake that collapsed the side of Mt Iriga and formed a dam (Alfaro et al. 2004).
