As unlikely as it sounds, there are a few species of snake in the world that are capable of eating humans. The vast majority of human deaths attributed to snakes are from venomous species, and while reports of a person being consumed by a snake are extraordinarily rare, there are a handful of confirmed cases in modern history. All potentially man-eating snakes must have one thing in common: immense size.

There are only two groups of snakes that grow large enough to be capable of both killing and eating a human: boa constrictors and pythons. Both kill through constriction, and some species are large enough to consume a human. Continue reading to learn about four snakes that are large enough to swallow a person whole.

Reticulated Python

The reticulated python (Malayopython reticulatus) is generally considered to be the longest snake in the world and is among the three heaviest. They are native to South and Southeast Asia and are hunted by humans for their beautifully patterned scales, from which the species gets its name. Although these snakes are dangerous, they are regularly sold as pets all over the world.

The largest reliably measured reticulated python was a captive specimen named Medusa that measured approximately 25.2 feet long. Large individuals in the wild usually grow to around 21 feet at a maximum and weigh up to 170 pounds, though a wild specimen measured in 2026 reached 23 feet 8 inches.

There are many stories of reticulated pythons killing humans, with at least two of them being eaten afterward.

African Rock Python

African rock pythons (Python sebae) are among the largest snake species in the world, although they aren’t as long as reticulated pythons. These snakes live across most of Africa and are grouped into two subspecies: the Northern African rock python (P. s. sebae) and the Southern African rock python (P. s. natalensis).

Rock pythons typically reach 10–16 feet in length, though exceptional specimens can exceed 20 feet. The largest snakes can weigh around 200 pounds and can take large prey like goats and some species of antelope.

While attacks on humans are very rare, there are a few confirmed fatalities, including a 2002 case in South Africa involving an African rock python and a 2017 case in Indonesia involving a reticulated python. The most commonly documented cases of this snake feeding on humans involve children, although the largest members of the species could potentially eat a smaller adult.

Burmese Python

Burmese pythons (Python bivittatus) are especially popular pets. Native to Southeast Asia, Burmese pythons have in recent years been introduced into the Florida Everglades, where they are classified as an invasive species, causing ecological damage, decimating native wildlife populations, and disrupting local food webs.

In the wild, Burmese pythons typically average between 6 and 9 feet, though some individuals have been recorded exceeding 18 feet, with the maximum on record reaching just over 19 feet. One captive specimen in Kansas measured 20 feet.

While rare, there are documented cases of captive Burmese pythons killing humans and, in at least one instance, attempting to swallow them whole. Based on their size, they certainly have the potential to do so.

Green Anaconda

The green anaconda (Eunectes murinus) is native to South America and lives in warm, swampy regions across the continent. Among all anaconda species, the green anaconda is the largest.

Green anacondas aren’t the longest snakes in the world, but they are the heaviest. Average lengths are 15–20 feet, with verified specimens reaching up to approximately 20 feet 9 inches. On average, green anacondas weigh between 66 and 154 pounds, although the largest ones can exceed 200 pounds.

The sheer size and mass of green anacondas make them a danger to humans. Despite this, no confirmed instances of an anaconda killing and consuming a human have ever been recorded. However, it is technically possible as they regularly consume capybaras and caimans.

Do Humans Eat Snakes?

Snakes are considered a delicacy in many cultures around the world, prepared in a variety of ways. In China, snake soup made with python or water snake is most common. People in Southeast Asia often eat cobras. In the United States, rattlesnake is a popular dish in the Southwest. The meat can be fried, barbecued, or stewed and reportedly tastes like chicken.

The indigenous people of Australia eat several types of wild bush meat, including pythons. Snake is usually cooked over an open fire and served with roots or tubers. In Africa, there are traditional recipes for snake meat in some areas. It is usually cooked with vegetables and spices such as onion, garlic, ginger, and pepper.
