How is venom made?

Answer 1

Venom originates from digestive enzymes that were originally located in the stomach of a snake. Throughout the millions of years it has progressed quite a lot and in some animals has become quite different from it's origin.

The type of venom depends on the type of animal. In Spiders venom is kept rather simple. It is pretty much just digestive enzymes. Spiders use their venom to turn their hard shelled insect meals into goo.

Insect venom is used predominantly as a defensive weapon. Wasps, bees and ants use formic acid in their stings to cause a painful burning sensation that will either kill or injure their enemy.

Answer 2

Venom was made by the extraction of an unknown species or dinosaur before it. Venom is a poisonous liquid that some animals are born with.
