Carpet Viper

The Carpet Viper is described as “Small and Deadly”

Most people are surprised to learn that these unassuming reptiles are responsible for more snake bite deaths than any other type of snake.

This includes the black mamba, which is said to kill people just by being found in the home. Carpet vipers are just not sexy.

They’re not very sleek or large in size and not possessed eye-catching colors.

Save the fiery flying serpent mentioned in the Bible, (which was most likely what’s now called Burton’s carpet viper) they don’t feature very prominently in the world’s folklore or mythology.

What they are is bad-tempered and extremely venomous. Of course, they do have their own down-to-earth beauty. Read on to learn more about this often-overlooked snake.

Carpet Viper Amazing Facts

• Most carpet vipers, such as the white-bellied carpet viper lay eggs, though female Echis carinatus snakes who live in India give live birth, or appear to. What really happens is the eggs hatch inside her and the hatchlings come out.
• The snake responsible for the most human deaths in Africa is the West African or ocellated carpet viper, a snake whose average length is 1 to a bit over 2 feet. It causes more snakebite deaths than all other types of African snakes combined. Unless the person gets bite treatment right away, they have a good chance of dying.
• The prettiest of these snakes are probably the Mali carpet viper and Burton’s carpet viper also called the painted carpet viper. Their colors and patterns are a bit more vivid than those of other carpet vipers.
• Biologists believe one reason these reptile predators are so successful is the variety of their diet. Basically, they’ll eat any animal they can handle, including other snakes and scorpions.
• The epithet for the Egyptian saw-scaled viper comes not from the country of Egypt, but from the pyramids.

Where To Find

Types of carpet vipers are found in Asia, Africa in the Middle East. The habitat depends largely on the species. For example, Burton’s carpet viper, also called the painted carpet viper is found in the Middle East and lives in rocky deserts.

The white-bellied carpet viper of West and Northwest Africa is found in habitats just on the edge of the desert, such as dry savannas and wadis. The ocellated carpet viper is sometimes found in the woods of West Africa.

Scientific Name

Carpet vipers belong to the Echis genus. Echis is simply the Greek word for “viper.” There are 12 species, and some, such as the Egyptian saw-scaled viper, have subspecies.

The Different Types

As of 2022 there are 12 species of carpet viper.

They are:

• E. borkini
• E. carinatus
• E. coloratus
• E. hughesi
• E. jogeri
• E. khosatzkii
• E. leucogaster
• E. megalocephalus
• E. ocellatus
• E. omanensis
• E. pyramidum
• E. romani

E. carinatus, the saw-scaled viper has five subspecies. These are:

• E. c. astolae
• E. c. carinatus
• E. c. multisquamatus
• E. c. sinhaleyus
• E. c. sochureki

The Egyptian saw-scaled viper, E. pyramidum has three subspecies. They are:

• E. p. aliaborri
• E. p. leakeyi
• E. p. pyramidum

These snakes resemble each other and identification can be tricky unless the person knows the snake’s native habitat. They are small snakes that have a pattern of blotches in earthen colors over a lighter or darker ground that’s also earth-colored, though the painted carpet viper and the Mali carpet viper are a little more vivid.

Evolution and Origins

Echis, also known as saw-scaled vipers or carpet vipers, comprises a group of vipers that inhabit the arid regions of Africa, the Middle East, India, Sri Lanka, and Pakistan. These vipers are known for their distinctive defensive behavior, where they create a “sizzling” warning sound by rubbing specific parts of their bodies together.

The earliest fossil records of vipers date back to the lower Miocene period. However, based on molecular phylogenies, it is believed that Viperidae originated even earlier, tracing its roots back to the early Eocene epoch.

Vipers first emerged in the Old World, and subsequently, pitvipers expanded into the New World, quickly colonizing and dispersing across North, Central, and South America.

Population and Conservation Status 

Though scientists don’t know exactly how many carpet vipers there are, they are fairly abundant in the locations where they are found. The conservation status of most is least concern, though the data is deficient for vipers such as the Mali carpet viper.

How To Identify: Appearance and Description 

Characteristics to look for in the identification of these snakes are a small, pear-shaped head on a narrow neck, a short round snout, round, large eyes, a short tail, and earth-tone coloration.

They are not large snakes, and even the largest species, such as the white-bellied carpet viper don’t grow more than 3 feet in length. Identification is further helped by examining the snake’s scales.

Most are keeled with a ridge going down the middle. Not only this, the scales on the snake’s side are angled at 45 degrees and are serrated. This gives the snake its other name a saw-toothed viper.

How Dangerous Are They?

Despite their small size and unshowy looks, members of the Echis genus cause not only the most snakebites but the most snakebite deaths on Earth.

They do this because they are both aggressive and easily overlooked. They also live in the same locations where people also live and work. Immediate bite treatment is a must, and these vipers often live in places where modern medical care is hard to come by.

The venom is especially dangerous because it is made up of the four main types of snake venom. One part attacks the nervous system, another attack the cardiovascular system, another the blood, and the last destroys the cells of the body in general.

Behavior and Humans

Carpet vipers are solitary save the breeding season. They’re usually active at dusk or at night, especially if the weather is rainy or humid. During the day they hide in old burrows, holes, logs, or under crags. If the snake lives in the desert, it may just dig into the sand with only its head poking out. On wet days, the snake climbs into trees or shrubs and can often be found there in large numbers.

The way the snake positions its body is another aid in its identification. It often curls its body into a figure 8 and rests its head in the center, which puts it in a good position when it’s ready to strike. Because these snakes are so bad-tempered, they aim to bite and envenomate when they do strike. When they’re about to strike they hiss and rub the saw-edged scales together, which produces a sizzling sound.

As so many are found in deserts, many Echis snakes move by sidewinding, which they perform with surprising speed.

The snakes mate in the winter and the babies are born from spring till late summer. Female E. carinatus snakes give birth to live young, while other snakes lay between 3 and 23 eggs. Their lifespan is on the long side for a viper, and the lifespan of a carpet viper can be about 23 years.

Like other snakes, they help humans by having a diet of pests such as rodents. Medicine has been made from the venom of snakes such as E. carinatus. Echistatin, for example, is an anticoagulant. But carpet vipers are so aggressive and venomous that they demand respect.
