SNAKES AND HUMANS

snake rule

The Interaction between snakes and humans occurs in many different ways

Snake bite

Snakes do not ordinarily prey on humans and most will not attack humans unless the snake is startled or injured, preferring instead to avoid contact. With the exception of large constrictors, non-venomous snakes are not a threat to humans. The bite of non-venomous snakes is usually harmless because their teeth are designed for grabbing and holding, rather than tearing or inflicting a deep puncture wound. Although the possibility of infection and tissue damage is present in the bite of a non-venomous snake; venomous snakes present far greater hazard to humans.

Documented deaths resulting from snakebites are uncommon. Non-fatal bites from venomous snakes may result in the need for amputation of a limb or part thereof. Of the roughly 725 species of venomous snakes worldwide, only 250 are able to kill a human with one bite. Although Australia is home to the largest number of venomous snakes in the world, about one snakebite proves venomous, on average, in a year; in India where 250,000 snakebites are recorded in a single year, as many as 50,000 initial deaths are recorded.

The treatment for snakebite is as variable as the bite itself. The most common and effective method is through antivenin, a serum made from the venom of the snake. Some antivenom is species specific or monovalent and some is made for use with multiple species in mind also known as polyvalent. In the United States for example, all species of venomous snakes are pit vipers, with the exception of the coral snake. To produce antivenin, a mixture of the venoms of the different species of rattlesnakes, copperheads, and cottonmouths is injected into the body of a horse in ever-increasing dosages until the horse is immunized. Blood is then extracted from the immunized horse and freeze-dried. It is reconstituted with sterile water and becomes antivenin. For this reason, people who are allergic to horses cannot be treated using antivenin. Antivenin for the more dangerous species (such as mambas, taipans, and cobras) is made in a similar manner in India, South Africa, and Australia with the exception being that those antivenins are species-specific.

Remember the majority of snake bites are avoidable, if people respect snakes and leave them alone in the wild, if people use a little common sense and most of all if people don't try to catch or kill them.

Snake charmers

In some parts of the world, especially in India, snake charming is a roadside show performed by a charmer. In such a show, the snake charmer carries a basket that contains a snake that he seemingly charms by playing tunes from his flute-like musical instrument, to which the snake responds. Snakes lack external ears, though have internal ears. However, snakes show no tendency to be influenced by music.

Researchers have pointed out that many of these snake charmers are good sleight-of-hand artists. The snake moves correspondingly to the flute movement and the vibrations from the tapping of the charmer's foot, neither of which is noticed by the public. Charmers rarely catch their snakes and the snakes are either nonvenomous or defanged cobras. Other snake charmers also have a snake and mongoose show, where both the animals have a mock fight; however, this is not very common, as the snakes, as well as the mongooses, may be seriously injured or killed.

Snake charming as a profession is now discouraged in India as a contribution to forest and snake conservation. In fact, in some places in India snake charming is banned by law.

Snake trapping

The tribals of "Irulas" from Andhra Pradesh and Tamil Nadu in India have been hunter-gatherers in the hot dry plains forests and have practiced this art for generations. They have a vast knowledge of snakes in the field. Irulas generally catch the snakes with the help of a simple stick. Earlier, the Irulas caught thousands of snakes for the snakeskin industry. After the complete ban on snakeskin industry in India and protection of all snakes under the Indian Wildlife (Protection) Act 1972, they formed the Irula Snake Catcher's Cooperative and switched to catching snakes for removal of venom, releasing them in the wild after four extractions. The venom so collected is used for producing life-saving antivenin, biomedical research and for other medicinal products. The Irulas are also known to eat some of the snakes they catch and are very useful in rat extermination in the villages.

Despite the existence of snake charmers, there have also been professional snake catchers or wranglers. Modern day snake trapping involves a herpetologist using a long stick with a "V" shaped end. Some like Bill Haast, Austin Stevens, and Jeff Corwin prefer to catch them using bare hands.

Consumption of snakes

While not commonly thought of as a dietary item by most cultures, in some cultures, the consumption of snakes is acceptable, or even considered a delicacy, prized for its alleged pharmaceutical effect of warming the heart. Western cultures document the consumption of snakes under extreme circumstances of hunger. Cooked rattlesnake meat is an exception, which is commonly consumed in parts of the Midwestern United States. In Asian countries such as Thailand, Indonesia, and Cambodia, drinking the blood of snakes, particularly the cobra, is believed to increase sexual virility. The blood is drained while the cobra is still alive when possible, and is usually mixed with some form of liquor to improve the taste.

In some Asian countries, the use of snakes in alcohol is also accepted. In such cases, the body of a snake or several snakes is left to steep in a jar or container of liquor. It is claimed that this makes the liquor stronger (as well as more expensive). One example of this is the Habu snake sometimes placed in the Okinawan liquor Awamori also known as "Habu Sake".

Snakes as pets

In the Western world some snakes, especially docile species such as the ball python and corn snake, are kept as pets. To supply this demand a captive breeding industry has developed. Snakes bred in captivity tend to make better pets and are considered preferable to wild caught specimens. See my Snakes As Pets page

The only difference between people who hate and love reptiles is that those who hate them never tried to know them.
Those who did become addicts.
