Cobras are highly venomous snakes that inhabit various habitats in Africa, the Middle East, and Asia.

Many can spit venom accurately from several feet away, and spread the skin around their heads and necks into a hood to appear larger.

Amazing Facts About Cobras

  • They create hoods by flattening their ribs and stretching out the skin.
  • Many can spit venom at predators, and some of the venoms cause burns to the eyes or broken skin.
  • Although they are very dangerous, cobras are also very shy.
  • After taxonomic revision in 2009, there are 38 species of snakes included in the Naja genus, but there may be more as scientists do more research.
  • The Caspian cobra and the Philippine cobra are the most venomous of all cobra species.

Where to Find Cobras

These snakes inhabit areas of rainforest and cultivated areas, they’re also found in deciduous forests, rice paddies, and sometimes urban areas. Some species, like the Arabian cobra, live in temperate climates with open savannahs and grasslands; still, others prefer arid climates.

Most cobra species are diurnal, and active during the day. In areas where temperatures soar during the summer, they shift their hunting habits to the early morning and late evening. Cobras, like other snakes, primarily eat rats and mice, but also take amphibians, lizards, birds and their eggs, and the king cobra eats other snakes.

These snakes mate in the spring, the timing of which depends upon whether they’re in the northern or southern hemisphere. They lay their eggs and bury them in leaves and dirt to help maintain a consistent temperature. Most species guard their eggs, but the king cobra mother builds a nest and then stays there to incubate them until the eggs hatch. Rinkhals, however, give live birth.

Cobras’ Scientific Name

All cobras are members of the Elapidae family of snakes. These snakes are highly venomous; some of their cousins are mambas and coral snakes. In 2009, several elapids were reclassified and a couple of them, including the water cobras and burrowing cobra of the Boulengerina subgenus. In doing so, the Naja genus grew to 38.

The genus Naja came from Sanskrit in the form of nāga; in Sanskrit, nāga is pronounced with a hard ‘g’ sound. Some believe it means snake, but others believe it’s a word that means hairless or naked.

Our common name for cobras was originally cobra de capello, and means “hooded serpent.” The Portuguese brought the term back from their travels when they first encountered the animal, but “Cobra” has its roots in Latin. Over time, the common name shorted to just, “cobra.”

Cobra Population and Conservation Status

According to the IUCN, of the 38 known cobra species, several are vulnerable, near threatened, or endangered, but most have healthy populations. While some species are decreasing in number, some are increasing or have stable populations. Areas, where the cobras live in remote or protected habitats, have stable populations. Many survival threats involve habitat destruction and being killed out of fear.

Cobras have few natural predators aside from people, but they are actively hunted by mongooses and boars. Both animals eat their eggs, but the mongoose is actually immune to their venom and cobras are a fairly regular part of their diet.

Identifying Cobras: Appearance and Description

Cobras are highly venomous snakes that are typically long, slender snakes reaching six to ten feet long, and king cobras can be 18 feet long. They have round pupils, varying head shapes, and a wide array of color patterns.

When a cobra spits venom, it’s more that they squeeze it out through their fangs. They have strong muscles that forcibly expel venom through their fangs. Many cobras have an opening on the front of their fangs which allows the venom to come out there, instead of the inside. Their fang structure varies; but except for the Indian cobra and Caspian cobras, all can spit venom to some degree.

Their hoods are defensive features that make them appear larger to a predator. However, many cobras forage with their heads up and off the ground in order to see better. Many cobras hiss and growl when threatened, but they are more inclined to seek escape than attack.

Types of Cobras

True Cobras inhabit areas of Africa, Asia, the Middle East, and Indonesia. They vary in length and color pattern, but all have hoods and raise up to one-third of their body off the ground.

King cobras and Rinkhals aren’t true cobras but look similar and are equally dangerous.

King Cobra Ophiophagus hannah – this snake eater used to be counted among the Naja group. However, genetic research and morphology show that it is its own species.

Rinkhals (Hemachatus haemachatus) – Also known as the Ring-Necked Spitting Cobra, a rinkhals has keeled scales and only lives in South Africa and Zimbabwe. It’s not a true cobra but looks similar.

Pictures and Videos of Cobras

Venom: How Dangerous are Cobras

These snakes are extremely dangerous and should be admired from a distance. A bite from one can mean death after very painful symptoms. Most elapids like cobras have strongly neurotoxic venom, however, those species that spit venom also have cytotoxins that can cause blistering.

Cobra snakebite envenomation symptoms depend on the species and can include drowsiness, nausea, vomiting, violent abdominal pain, cramps, swelling, bruising, blistering around the site of the bite, labored breathing, rapid heart rate, weak pulse, and diarrhea.

If you are bit by a cobra or one of its cousins, seek treatment immediately.

Venom in Medicine

Cobra venom is highly valuable to medical research. A number of medicines including blood thinners and heart medications have been created using some of the components in venom, and anticancer and anti-inflammatory medicines are being created and tested.

Venomics, the study of venom, is an exciting field with a lot of potential to help people in the future.

Cobra Behavior and Humans

Cobras and their hooded cousins are often shy and would rather flee than fight. These snakes aren’t generally aggressive, but they will defend themselves. Some are known to stand their ground and even defend their nests from predators.

Although these snakes seem frightening, they are an integral part of the natural balance. Without cobras and other snakes, we would be overrun by rodents.
