Malabar Pit Viper

Craspedocephalus malabaricus

Also known as Malabar Rock Pit Viper, Rock Viper

Malabar pit vipers exhibit striking color polymorphism, ranging from vibrant green and yellow to earthy brown, blue, or reddish-orange with dark diamond markings. Endemic to the Western Ghats, these nocturnal ambush predators spend rainy nights perched motionless on low foliage or wet rocks along forest streams. Heat-sensing pit organs located between their nostrils and eyes allow them to strike warm-blooded prey with deadly precision in total darkness.

Safe observation
Interaction riskVery high
  1. Low
  2. Moderate

  4. Very high
Why interaction risk is very high
Delivers a painful hemotoxic bite; maintain a safe observation distance of at least two meters.
Why it is dangerous
Delivers a potent hemotoxic venom that causes severe local swelling, intense pain, tissue necrosis, and systemic blood clotting complications.
How to recognize a risky encounter
Look for a distinct triangular head, vertical pupils, heat-sensing pits between the eyes and nostrils, and highly variable blotched coloration.
What to do
Freeze immediately if encountered on a trail, then slowly back away without making sudden movements.
What to notice
Recognized by its broad triangular head and broad-banded or mottled pattern while perched near monsoon streams in southwestern India.
Support conservation
Remain strictly on designated trail paths to avoid crushing hidden microhabitats or disturbing brooding females.
Responsible observation
  • Night Spotting: Scan low-hanging branches and streamside boulders with a dim torch during monsoon rains.
  • Safe Spacing: Keep a respectful distance of several meters as they can strike quickly if threatened.
  • Avoid Touching: Never attempt to handle or poke camouflaged snakes resting along forest trails.
