“The Spitting Cobra Evolved to Deter Humans”

When a spitting cobra spits it aims for the eyes and frequently hits the target. It makes you wonder how a snake knows where and what a human’s eyes are. Some biologists believe that the ability to accurately aim at the eyes evolved in cobras, who are much older than Homo sapiens, when humans first came on the scene and started harassing them. In other words, the reptile may not know where your eyes are and how much you value your sight, but nature does. Read on to learn more about these fascinating animals.

• Some spitting cobras can spit venom as far as 10 feet.
• Ashe’s spitting cobra is the largest spitting cobra and can grow over 8 feet in length.
• Their venom might cause some blistering if it lands on your skin but can blind you if it lands in your eyes.
• The Indochinese spitting cobra has the smallest spitting range of the other spitters at around 3.3 feet. It also sprays a mist as opposed to a stream.
• Identification of a spitting cobra can be done by examining the fangs. The opening in the fang of the spitting cobra is much smaller than the opening in the fang of a “regular” cobra.

Where To Find Spitting Cobras

These venomous reptiles are found in Africa and Asia. Habitats range from the savannas, deserts, and tropical forests of Africa to the mangroves, swamps, and rice paddies of Asia. Habitats also include pastures, jungles, places where people live and work, and locations as high as 6600 feet.

Spitting Cobra Scientific Name

Most spitting cobras belong to the Naja genus. The one exception is the rinkhals, which is the only member of the Hemachatus genus. It is different from the other spitting cobras in that its scales are somewhat keeled and ridged. Naja is derived from Naga, a Sanskrit word that simply means “snake.” Hemachatus comes from the Greek words haima, which means “blood” and achatēs, which means “agate,” so the name means blood-colored agate. Interestingly, the rinkhals is not considered a “true” cobra, though it is grouped with the spitting cobras.

The Different Types of Spitting Cobra

There are about 20 species of spitting cobra. Some of them greatly resemble each other and identification can only be made through close inspection of the snake. For example, the Chinese and monocled cobras look very much alike but have different numbers of scales in their abdomens and beneath their tails.

Spitting cobras, with the exception of the rinkhals, are also considered true cobras though scientists aren’t quite sure what “true cobra” means. Many biologists claim that a true cobra can only belong to the Naja genus. These snakes can expand and flatten their ribs and their head to create a hood and rear up in a defensive posture. They spit by using muscles to squeeze their venom glands and force the venom out through small holes in their fangs.

Spitting Cobra Population & Conservation Status 

Though biologists don’t have the exact number of spitting cobras in the world, the conservation status of most is least concern. Exceptions are the Indonesian cobra and the Chinese cobra, whose status is vulnerable.

How To Identify Spitting Cobra: Appearance and Description 

Identification of a spitting cobra can be challenging, for they look like any other type of cobra, and some even crossbreed with other cobras who live in their area. Unless a person is a herpetologist who specializes in cobra species, the one way a person can know they have a spitter is if the snake actually spits. Some biologists believe that all members of Naja have at least the ability to spit.

Besides examination of the fangs, the venom of a spitter is more cytotoxic than the venom of other cobras. Cytotoxic means that the venom destroys cells, which is why skin sometimes blisters if a cobra spits on it. Scientists believe that the ability to spit evolved three times over the course of the cobra’s evolution. The venom that’s spat out rarely kills but causes enough damage to make would-be predators avoid the snake in the future.

Besides the ability to create a hood, most of these snakes have slender bodies, though N. ashei is a bit more robust. They are not the biggest snakes in size, and it is rare to find one over 10 feet. Their colors range from red to brown to gray to glossy indigo black, and they may have bands, monocles at the back of their hood, spots, or mottling. Besides spitting, all of them can still bite, and their bite can be fatal.

Spitting Cobra vs King Cobra

Interestingly, the king cobra is not considered a “true cobra.” It is the only member of the Ophiophagus genus and gets its common name because it is much larger in size than other cobras and indeed preys upon them. The king cobra is found only in the south and southeast Asia, can grow as long as 19 feet, and has what some describe as a growl as opposed to a hiss. A grown individual is not particularly aggressive and would rather avoid a fight. Yet it has been known to leap off the ground at an attacker, bite and hang on while pumping lots of venom into the wound.

Another thing that separates the king cobra from spitting cobras is that it makes a nest of dead leaves where it lays and incubates its eggs. No other snake does this. Unlike most spitting cobras, the king cobra is considered vulnerable because of habitat loss.

Spitting Cobra Venom: How Dangerous Are They?

Some of the most venomous members of the entire Naja genus are the Philippines, Indochinese, Samar, and Chinese spitting cobras. Like other cobras, the venom of spitters evolved to attack the nerves and cardiac cells, but it is good at disrupting cells in general. Because of this, the venom that enters the eyes can cause blindness if the eyes aren’t quickly treated.

If the cobra bites and envenomates its victim, it’s important that they get medical help as soon as possible. The venom can paralyze the person as it attacks the nerve cells, prevent blood from coagulating and cause necrosis. This can all lead to death. It also needs to be said that baby cobras are venomous from birth.

Spitting Cobra Behavior and Humans

Spitting cobras are solitary animals. Many are nocturnal or crepuscular and are less aggressive if they are caught out during the day. Other cobras such as the Chinese cobra are active day and night. Many cobras choose to live in locations near water and can be said to be semi-aquatic, like N. kaouthia. The diet of juveniles is often frogs or toads, while adults have small mammals, fish, and even other snakes as prey. When they’re not hunting they hide in burrows or tree holes.

Cobras are often apex predators where they live, but some, like the Javan spitting cobra, are sometimes victims of even more robust predators such as the Komodo dragon. Mongooses and pigs also steal their eggs.

The snakes are ready to mate when they’re about two or three years old. The pair engages in a courtship ritual that involves swaying and dancing before they mate, which is often during the rainy season in the locations where they live. The females can lay anywhere from two to 23 eggs after being gravid for about three months. The eggs hatch after 48 to 120 days. Depending on the species, the female may or may not guard the eggs. The lifespan of one of these cobras is about 20 years.

These snakes are helpful to humans because they eat pests that might eat or damage crops, but their ability to both inject and spurt dangerous venom demands that they are treated with respect.
