Do snakes always inject venom when they bite?

Many snakes will not inject venom in their victim’s bodies through the use of hollow fangs, and this is a common misconception. Dry bite is the name given to the bite from the venomous animal that does not carry venom when it is released. The dry bites may take place with every snake, but the frequency will depend on which species. At least 25 percent of snake bites are dry bites. They are known by the tooth and fang marks but there is no injected venom. Sometimes, a dry bite can be confused for venomous bites by the victims or physicians.



For many people, snakes and venom work hand in hand, but this is one common belief which is not true. There are over 2700 species of snakes and among them only 300 are known to be venomous. The venom is the poison that is secreted by the animals for offensive and defensive purpose. The venom comes from enzymes found in their stomach. As time has passed, the venom has evolved and many snakes have different types of venom.

Snake venom is divided into two categories. There are neurotoxicity and hemotoxicity. The hemotoxic venom may affect the organs and blood, which may cause inflammation and breakdown in a body. A hemotoxic bite is the most painful since it hurts and the tissue will start to die off. Neurotoxic venom will affect the nervous system and it leads to seizures and then to death. The neurotoxic bite is the most deadly. However, one snake may have two options when it comes to their venom, and it is hard to know which snake has which venom.

Whenever a person is bitten by a snake, he will worry about the venom right away. The fangs are not the glands that secrete the venom, but they are only the method to transfer the venom. The venom is secreted in the glands found at the top of the head of the snake. The glands are also categorized in true or false venom glands.

The venom in the snakes takes time to make and it cannot refill easily when it is emptied. Sometimes the snake may decide to save its venom for an emergency. This is why the snake may not always inject the venom whenever they bite their prey or they may use other strategies to avoid having to bite people. However, the constrictors do not have the venom and they do not worry about wasting it, so they may bite as many times as they want. Since it is hard to know when a bite is dry or not, it is necessary to see a doctor as soon as possible, after you are bitten by a snake.
