Chequered Keelback
Fowlea piscatorAlso known as Checkered Keelback, Asiatic Water Snake, Common Keelback
Chequered keelbacks are highly active, semi-aquatic hunters common in rice paddies, rivers, and freshwater ponds across South and Southeast Asia. When threatened, they often flatten their head and forebody into a cobra-like hood while striking aggressively, though they produce no venom. Females are remarkably prolific, laying clutches that can exceed eighty eggs buried in moist soil near the water's edge.

Interaction riskLow
- Low
- Moderate
- High
- Very high
- Why interaction risk is low
- Non-venomous, but bites aggressively if cornered or handled; observe from a respectful distance.
- Why it is dangerous
- Although completely non-venomous, it possesses sharp recurved teeth and strikes repeatedly when provoked, causing painful lacerations prone to secondary infection.
- How to recognize a risky encounter
- Look for a checkered pattern of black spots on an olive or brown body, heavily keeled rough scales, and two dark streaks extending behind each eye.
- What to do
- Give the snake ample room to retreat into water or vegetation, and never corner or attempt to pick it up.
Responsible observation
- Observation: Watch quietly along the muddy banks of ponds or flooded paddies during early morning.
- Handling: Do not attempt to capture; they bite repeatedly and release a foul-smelling musk.
- Safety: Verify markings carefully to avoid mistaking venomous co-occurring species like cobras or vipers.
