Why do snakes have fangs?

Introduction: Understanding the Function of Snake Fangs

Snakes are known for their unique physical features, including their long, slender bodies and their ability to swallow prey whole. One of the most distinctive features of snakes, however, is their fangs. These sharp, pointed teeth are located in the upper jaw and are used for a variety of purposes, depending on the species of snake. While fangs are often associated with venomous snakes, not all snakes have venom in their fangs. In this article, we will explore the different types of snake fangs, how venomous snakes use them to inject venom, and the evolution of snake fangs.

Types of Snake Fangs and Their Characteristics

There are several different types of snake fangs, each with its own unique characteristics. The most common type of fang is the solenoglyphous fang, which is found in venomous snakes such as cobras, vipers, and rattlesnakes. These fangs are long, hollow, and located at the front of the mouth. When the snake bites its prey, the fang is used to inject venom into the victim. In contrast, non-venomous snakes such as boas and pythons have teeth that are not specialized for injecting venom. They have small, sharp teeth that are used for biting and holding prey.

Another type of fang is the opisthoglyphous fang, which is found in a small number of venomous snakes. These fangs are located at the back of the mouth and are angled backwards. When the snake bites its prey, it must hold the prey in its mouth and move its lower jaw forward to inject the venom. Finally, some snakes have aglyphous teeth, which are small, non-specialized teeth that are not used for injecting venom. These teeth are found in both venomous and non-venomous snakes and are used for biting and holding prey.
