Size & venom sources

Venom: Denmotoxin blocks nerve–muscle signalling in bird preparations, with much weaker activity in mouse preparations. This purified-toxin result is not a prediction of a human bite outcome.

Dashevsky et al. (2018), Abstract; Pawlak et al. (2006), Abstract and nerve–muscle experiments

Venom effects and medical significance are different from toxicity rankings. Do not handle a snake on the basis of this summary.

A striking tree snake associated with riverbank vegetation. In Palawan, resting animals have been documented on mangrove branches along the Iwahig River.

RDB internally contradicts its accepted Bornean annectens subspecies with a not-Borneo comment. Primary Weinell et al. 2020/2021 retains annectens and Pui/Das field record confirms Sarawak; Borneo retained under that taxonomic concept. Continental records belong to melanota and are omitted.

Boiga melanota is treated separately; continental records under that former subspecies are not transferred to dendrophila.

A closer look

Natural history & identification

Ecology & habitat

Uses mangrove vegetation along the Iwahig River, including a semi-disturbed riverbank.

Evidence & scope

Literature documented · Account, Iwahig observations

Palawan population treated as B. d. multicincta.

Behaviour

Several individuals rested on mangrove branches above the riverbank; one approximately two-metre animal occupied Scyphiphora hydrophyllacea.

Evidence & scope

Literature documented · Account, Fig. 1 description

Direct resting-site observations.

Encounter frequency is not a population-density estimate.

Conservation pressures

Habitat degradation and illegal collection are local conservation concerns. The 2014 account highlights the need for habitat protection and trade monitoring.

Evidence & scope

Literature documented · Account, conservation discussion

Palawan; dated conservation context.

No current trade volume or Red List category is inferred.

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 Boiga dendrophila from these named Philippine areas: Luzon, Palawan, Mindanao, Panay, Polillo, Balabac. 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

Boiga dendrophila 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.

Evidence & scope

Literature documented · Checklist identity and nomenclatural trail

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

Living with wildlife

Give this snake space.

Venomous · rear-fanged · Neurotoxic · bird-selective denmotoxin (laboratory)

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

Phylogenetics: DNA barcodes suggested multiple species within this species (Laopichienpong et al. 2016). Weinell et al. 2020 elevated Boiga dendrophila melanota (BOULENGER 1896) to full species status and indicated the future elevation of B. d. annectens, B. d. levitoni, B. d. divergens and B. d. occidentalis to full species. However, Weinell et al. 2021 did not follow through with the latter recommendation. They also found that gemmicincta is closely related to dendrophila and may not warrant subspecies status. Habitat: partly arboreal (Harrington et al. 2018). Distribution: Reports from Singapore represent D. melanota. See also Figueroa et al. 2023. Not in Borneo fide Das 2023.
