What is the most venomous snake in the world?

Kid Zach really wishes an answer to the most venomous snake question would have existed in his childhood when library books could not answer the question.

Deadliest vs. most venomous snake

The first thing we need to do when answering this question is to distinguish between the mostly deadly vs. the most venomous. When we read deadly, this term refers to how many deaths are caused by the snake species, whereas most venomous means the snake venom has the most potency for each milligram of venom per kilogram of the prey item.

This article will cover both terms based on the most updated research and data available. Some studies may be a few decades old, as they sufficiently answered the venom potency question with their initial work. Envenomation deaths are not well-tracked, as most snakebite deaths occur in countries where data may not be regularly collected or tracked. Southeast Asia, South Asia, sub-Saharan Africa, and many tropical countries experience the greatest number of snake-caused deaths. This is both due to populations near highly venomous species and a lack of healthcare available to snakebite victims.

Deadliest snake in the world

This question is quite difficult to answer when compared to the next question. However, it is estimated that either the monocled cobra or the saw-scaled viper kills more humans every year than any other snake species. This makes either a cobra or saw-scaled viper the deadliest snake in the world. The tracking of envenomation deaths is not accurately tracked in the countries where the most snake bite deaths likely occur.

Most venomous snake in the US

The United States does not experience many deaths due to snakebite. However, our most venomous and possibly most dangerous snake is the eastern diamondback rattlesnake (Crotalus adamanteus). Its rank versus the other global venomous snakes places it in the mid-20s. However, it has one of the greatest venom yields. So, while this rattlesnake is quite dangerous, its true danger lies in the amount of venom it can dispense into predators or prey. For humans, only a lack of medical care would pose the greatest risk from this species.

Some may argue, with good cause, that timber rattlesnakes (Crotalus horridus), Mojave rattlesnakes (Crotalus scutulatus), and eastern coral snakes (Micrurus fulvius) are all equally or more venomous than the eastern diamondback rattlesnake. However, different forms of venom tests can produce varying results. All four species are extremely dangerous and should be avoided at great lengths.

One note of caution, depending upon location, some snakes of the same species can vary in venom composition and toxicity. Timber Rattlesnakes in the southern extent of their range are more likely to have neurotoxic venom than their northern counterparts. The same goes for the Mojave Rattlesnake, which has far more neurotoxic venom in the southern part of its range than in the United States portion of its range.
