Venom effects and medical significance are different from toxicity rankings. Do not handle a snake on the basis of this summary.
The account records a marine habitat. Island names on the map identify reported coastal areas; they are not land occupancy or a boundary of the species’ marine range. Philippine occurrence is listed, with island-level detail still unresolved.

Coastal island outlines are geographic context, not a mapped marine range.
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.
Reproductive mode reported for this named species.
Mode alone does not establish litter or clutch size, seasonal timing, or captive husbandry requirements.
Ecology & habitat
The account records a marine habitat. Island names on the map identify reported coastal areas; they are not land occupancy or a boundary of the species’ marine range.
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.
Taxonomic context
Hydrophis peronii is retained in the atlas’s dated checklist under Elapidae. The authority is (DUMÉRIL 1853). Earlier names and the original source notes are preserved below for comparison.

Venomous · 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.
