Top 15 Deadliest Snakes In The World

This cold-blooded reptile is found everywhere around the world except in Antarctica, Iceland, New Zealand, Ireland and Greenland. The long, scaled reptile that doesn’t use its teeth to chew its prey but rather prefers to swallow it, the snake is one of the most dangerous animals. With their elastic ligaments, strong sensing vibrations and powerful digestive enzymes, they make sure that none of their feeding tactics fails. According to recent reports presented by scientists, there are approximately 3600 known species of snakes in the world. About 600 species are venomous and only 200 species are dangerous enough to kill humans. Another
an interesting fact about this species is their habitat. While most of the snakes dwell on land, there are 70 species that live in the sea. Snakes and other beings haven’t been great friends but here is a list of snakes who are ruthless and deadliest.

Deadliest Snakes In The World

1. BELCHER’S SEA SNAKE

A member of the elapid family, Belcher’s sea snake or faint-banded sea snake is an extremely venomous snake and thus one of the top ten deadliest snakes. The sea snake that feeds on small fishes and eel is considered to be the most poisonous snake as its venom is 100 times more deadly than the most poisonous terrestrial species. The high level of neurotoxins and myotoxins in its venom is so lethal that it can kill 1800 people. Its single bite can kill a person in less than 30 minutes. However, Belcher’s sea snake’s shy temperament saves humans from being its prey.

Its average length is 5.9 feet. Unlike other species of snakes, Taipan feeds only on mammals and over time its venom has evolved to be fatal to mammals.

3. BLUE KRAIT

One of the deadliest snakes in the world and the deadliest snake in Asia, Blue Krait is identified by the bluish-black crossbands that run over its body and are separated by yellowish-white interspaces.

People don’t experience pain upon the bite of Blue Krait.
