Do Spiders Have Teeth Or Fangs?
If you’ve ever seen a spider, you may have wondered “Do spiders have teeth?” Spiders, in general, do not have teeth. However, some species do have chelicerae. Chelicerae are like jaws, but they are not teeth.
A chelicerae is a two-part structure, and they’re important in a number of ways. Firstly, they are used to catch prey. They’re also useful for mating.
Secondly, they’re useful for piercing the skin of prey. The chelicerae are similar to a pair of pliers, and are loaded with muscles. In addition, they fold together like a folding knife.
Finally, chelicerae are a handy way for spiders to suck up liquid from prey. Some spiders are even able to use them to liquefy the contents of their prey.
One reason for this is that the venom in spider venom is enzymatic. Enzymatic proteins break down muscle tissue, and thus, the venom is able to penetrate and liquify the prey. This isn’t as simple as it sounds, however.
Aside from the opulent chelicerae, spiders have two other fang-like structures. These are called pedipalps, and they’re useful for detecting their surroundings.
However, the pedipalps aren’t actually “teeth.” Instead, they’re tiny limbs. Similarly, the smallest fang in the world isn’t actually a tooth.
To summarize, a spider’s fangs are a great tool for catching and killing prey, but they’re not the most important part of a spider’s anatomy. Their other teeth aren’t needed for eating, and they aren’t exactly useful for piercing the skin of a prey.
