A closer look
The revision describes 15 midbody dorsal scale rows, an enlarged vertebral row and a divided anal shield. The tail forms roughly one-third to two-fifths of total length in the reported sample.
Literature documented · Diagnosis; tail/total-length ratio 0.33–0.39
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 egg-laying reproduction. A verified Philippine clutch-size range, incubation interval and breeding 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 species account characterises this snake as tree-dwelling. That broad ecological category does not establish canopy height, forest dependence or tolerance of habitat disturbance.

The atlas records Dendrelaphis marenae from these named Philippine areas: Luzon, Mindoro, Palawan, Mindanao, Samar, Leyte, Panay, Negros, Cebu, Bohol, Catanduanes, Basilan, Polillo, Masbate, Siargao, Sulu, Camiguin, Busuanga, Balabac. These are literature areas rather than a continuous range boundary.

The original evidence level is retained.
A country listing cannot establish an island or a precise locality.
Dendrelaphis marenae is retained in the atlas’s dated checklist under Colubridae. The authority is VOGEL & VAN ROOIJEN 2008. Earlier names and the original source notes are preserved below for comparison.

Living with wildlife
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.
