Why do some animals produce venom?

Venom is produced by many animals as a means of defense, hunting, or protecting territory. For example, snakes and spiders use venom to immobilize or kill prey, making it easier to consume. In some species, such as scorpions, venom is used as a deterrent against predators. Additionally, venom can be a means of defending a territory, as seen in certain amphibians and reptiles. The production of venom is an evolutionary adaptation that enhances an animal’s survival by allowing it to either capture prey or protect itself from threats.
