Distribution area Xenochrophis piscator Xenochrophis piscator (Checkered Keelback)
Thai:
(ngu lai so yai, ngu daeng hae)

Length: Up to 120 cm

Distribution area: Throughout Thailand in heights up to 1600 meters; more commonly found in flat land up to a height of 300 meters.

Habitat and behaviour: Xenochrophis piscator can mainly be found near waters. The snake is usually active during the day and often covers large distances on the hunt for food. Many can be found on the streets after a heavy rainfall. If agitated the snakes flatten out their neck region and erect their upper bodies. Due to this defensive reaction they are often mistaken for a cobra. When fleeing the snake moves along smooth surfaces (e.g. streets) in sideways movements and jumps forwards.

Danger level: The snake is not dangerous to humans. If they are threatened or even simply taken in the hand, they do bite very quickly. Whitaker & Captain claimed that they swam in ponds inhabited by fish snakes and were never bitten.
