SNAKES AND THEIR FANG STRUCTURE IN SOUTH AFRICA.

The different species of venomous snakes have different fang structures, venom types and different delivery methods to inject their venom.

The delivery methods and fang structures depend on various factors such as habits, prey and the environment where the snake lives. Essentially fangs are modified teeth and have a specific role to play in aiding snakes deliver their fatal dose of venom into their prey. A snake will replace its fangs throughout its life, should a fang become damaged during feeding it will fall out and a replacement will be waiting just behind it – much like that of a sharks tooth.

With opening at base to inject venom, much like a hypodermic needle, the fangs are long and fold into a sheath which sits on the roof of the mouth until the fangs are extended when biting prey.

Opening at the base to inject venom – here a unique case where a double fang is present. As one fang is damaged another will take its place much like sharks teeth.
