Hydrophis curtus(SHAW 1802)
Venom: Basic classification explicitly recorded in the species account. Detailed effects and medical significance have not yet been summarised here.
Species account, Comments
Venom effects and medical significance are different from toxicity rankings. Do not handle a snake on the basis of this summary.
The three or four lowest lateral scale rows are enlarged. Dark bands cross a greenish or yellowish upper surface and can join along the back. Its atlas account links 1 named island or island-group record to the source literature.

Media provenance
Contributor images are forthcoming. Photographs and illustrations will retain their individual credits, permissions and evidence notes.
A closer look
One of the principal sea snakes in the skin trade. Fisheries bycatch and commercial harvest are important regional pressures.
Literature documented · Abstract
Indo-Pacific review of 1974–2022 literature and trade data.
Does not quantify Philippine population decline or establish a current legal listing.
The three or four lowest lateral scale rows are enlarged. Dark bands cross a greenish or yellowish upper surface and can join along the back.
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.
The database warns that distribution and synonymy still require adjustment following recognition of H. hardwickii. Older records under H. curtus may represent the broader historical concept.
Literature documented · Comment: taxonomic scope
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.
The species account records live-bearing reproduction, using the term ovoviviparous. A verified Philippine litter-size range and reproductive calendar are not established here.
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.
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.
The atlas records Hydrophis curtus from these named Philippine areas: Panay. 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.

Coastal records: blue outlines
Blue outlines locate coastal records, not land occupancy or marine range boundaries.
Philippine distribution
Select an island to read its distribution record and sources. Uncoloured islands are not evidence of absence.

Living with wildlife
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.

Venomous! Synonymy: Voris and Gritis (1990) included Lapemis hardwickii Gray, 1834 in the synonymy of L. curtus Shaw, 1802. Remaining synonymy mainly after STEJNEGER 1907. Distribution not yet corrected for resurrection of hardwickii from curtus. For a map see Sindaco et al. 2013. Records from Japan are doubtful and there are apparently no known voucher specimens (Ibuki Fukuyama, pers. comm., 8 Sep 2023) Habitat: marine. Genome: Ludington et al. 2023.
