Terciopelo

Bothrops asper

Terciopelos are large pit vipers patterned with pale-edged dark triangles that disappear against damp leaf litter. They hunt from ambush, commonly resting motionless on the forest floor and defending themselves forcefully when approached too closely.

  4. Very high
Why interaction risk is very high
Highly venomous and defensive at close range; stay several meters away and seek emergency care immediately after any bite.
Why it is dangerous
Proteolytic and hemotoxic venom can cause extreme pain, swelling, tissue destruction, systemic bleeding, shock, and death without prompt treatment.
How to recognize a risky encounter
Identify a broad triangular head, heat-sensing facial pits, and dark triangular side markings edged with paler color.
What to do
Never approach, move, or provoke the snake; retreat slowly and obtain emergency medical care after any possible bite.
Responsible observation
  • Ground: Scan leaf litter ahead without stepping off a clear trail.
  • Pattern: Look for pale-edged triangular marks along a heavy brown body.
