Overview
The Zayu Mountain Pit Viper is a rarely documented member of the Ovophis group, described from specimens collected in the deep valleys of southeastern Tibet's Zayu region. Its restricted distribution and remote habitat mean it remains poorly studied compared to more widespread relatives.
As with other members of its genus, it is a stout, ground-dwelling pit viper adapted to cool, high-elevation forest conditions.
How to identify it
- Stocky, short-tailed build typical of the Ovophis pit vipers
- Brownish to grayish ground color with darker, irregular blotches along the back
- Broad, triangular head with heat-sensing pits between eye and nostril
- Vertically elliptical pupils
- Keeled scales giving a rough dorsal texture
- Best distinguished from closely related species through fine scale-count and morphological comparison, given its overlapping general appearance
Habitat & range
Occurs in montane forest habitats of the deep river valleys of southeastern Tibet and adjacent Yunnan, typically at high elevation where cool, humid conditions prevail among forest leaf litter and rocky ground.
Behavior, diet & reproduction
Presumed nocturnal and terrestrial like its congeners, sheltering under forest debris during the day. Likely feeds on small mammals and amphibians. Believed to be oviparous, consistent with other Ovophis species, though detailed reproductive data are limited.
