Overview
The black-ringed mangrove snake is a distinctively patterned sea snake found along mangrove-fringed coastlines of the northern Bay of Bengal, where it navigates root systems and tidal creeks in search of prey. Its bold black rings make it one of the more visually striking coastal sea snakes.
It occupies a habitat niche shared with several other banded Hydrophis species, and its ecology is closely tied to the health of mangrove ecosystems throughout its range.
How to identify it
- Pale body crossed by bold, evenly spaced black rings
- Rings encircle the body completely, wider on the back than the belly
- Small head not distinct from the neck
- Compressed, paddle-shaped tail
- Distinguished from similar banded sea snakes by the crispness and regularity of its black rings

Behavior, diet & reproduction
Hunts small fish among mangrove roots and tidal channels, likely relying on both stealth and chemical cues in turbid water. Fully aquatic and live-bearing, with reproduction tied to coastal tidal cycles.
