Overview

The Indochinese spitting cobra is widespread across Thailand, Cambodia, Vietnam, and Laos, where it is a familiar and sometimes locally common snake near villages and farmland. It is often mottled or speckled in gray, black, and cream tones, giving it a distinctive marbled appearance compared to some other Asian cobras.

It is an elapid often found near humans, with a tendency to shelter in and around buildings.

How to identify it

  • Adults typically 0.9-1.2 m; relatively small to medium cobra.
  • Coloration variable, often gray, brown, or blackish with irregular pale mottling or speckling, though some individuals are more uniform.
  • Smooth scales, round pupils, moderately narrow hood.
  • Distinguished from Thai spitting cobra relatives by mottled pattern and range across mainland Indochina.

Found in lowland forest, agricultural fields, rural villages, and disturbed habitats across Thailand, Cambodia, Vietnam, and Laos, frequently sheltering in termite mounds, rock piles, or under buildings and debris near human settlements.
