Spiders, Crustaceans, Centipedes, and Their Fangs and Claws

What is the purpose of spiders' fangs?

A. Injection of venom

B. Catching prey

Answer: A. Injection of venom

Spiders use their fangs to inject venom into their prey. This venom helps to immobilize or kill their prey for consumption. It is an essential tool for spiders in hunting and feeding.

In contrast, crustaceans, such as crabs and lobsters, use their claws for a different purpose. Crustaceans mainly use their claws for defense, feeding, and handling their environment. While centipedes also have claws, they do not use them for injecting venom like spiders do.
