9 Deadliest Snakes in the World


Some of the world’s deadliest snakes are aggressive and quick-to-strike, while others pack potent venom but will only bite as a last resort. 

Here’s a look at the nine deadliest snakes, fearsome creatures for their stealth as well as their poison. 

 

9. Black Mamba (Dendroaspis polylepis)

Region: Central, Eastern Africa

Average length: 7 to 9 feet (2 to 3 meters)

The black mamba’s venom can kill a human in half an hour to two hours if the victim isn’t treated with an anti-venom injection. Early symptoms include drowsiness, neurological problems, paralysis, and trouble breathing.

This snake is aggressive and fast-moving. It dwells in trees and scrub. The black mamba isn’t actually black. It varies in color from olive to brown.

 

8.  Terciopelo (Bothrops asper)

Region: Southern and Eastern Mexico, Central America, Northern Colombia and Ecuador

Average length: 4.5 to 6 feet (1 to 2 meters)

The Terciopelo’s venom attacks the blood, causing clots that are deadly. It has many names, varying from region to region, including barba amarilla, macagua, yellow beard, yellow chin, and fer-de-lance.

Offspring grow inside the female’s body, and a single snake can give birth to up to 100 offspring.

 

7. Boomslang (Dispholidus typus)

Region: Central, Southern Africa

Average length: 4 to 5 feet (1.2 to 1.5 meters)

This snake mimics a tree branch when it hunts, extending itself, nearly motionless from a tree. The boomslang is a rare example of a rear-fanged snake that can kill humans, as rear-fanged snakes usually deliver small amounts of venom slowly.

The boomslang typically only bites if handled. It dwells in a variety of ecosystems, though it tends toward moist areas rather than desertous regions, living in low-lying shrubs and short trees. Its lifespan is about eight years.
