Venom: Genus-level classification: the taxonomic literature characterises Calamaria reed snakes as nonvenomous. This is not a species-specific venom assay.
Venom effects and medical significance are different from toxicity rankings. Do not handle a snake on the basis of this summary.
Calamaria virgulata is a Colubridae snake included in the Philippine checklist. Its atlas account links 3 named island or island-group records to the source literature.

Natural history & identification
Reproduction
The species account records egg-laying reproduction. A verified Philippine clutch-size range, incubation interval and breeding calendar are not established here.
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 Calamaria virgulata from these named Philippine areas: Palawan, Mindanao, Sulu. These are literature areas rather than a continuous range boundary.
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
Calamaria virgulata is retained in the atlas’s dated checklist under Colubridae. The authority is BOIE 1827. Earlier names and the original source notes are preserved below for comparison.
Literature documented · Checklist identity and nomenclatural trail
Checklist verified 2026-09-05; not a newly revised taxonomic backbone.
Historical names can cover different biological concepts; synonyms should not be used to transfer records automatically.

The atlas records Calamaria virgulata from these named Philippine areas: Palawan, Mindanao, Sulu. These are literature areas rather than a continuous range boundary.
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.

Introduction explicitly characterises Calamaria as nonvenomous. Used only for that genus-level classification, not to transfer measurements or ecology of C. andersoni to Philippine species.
