This is untrue. The only times fangs are removed are before they are cooked and eaten in some countries. You can't remove a tarantula's fangs as that need them to eat. They inject venom through their fangs, which breaks down the insides of their prey into a soup, then they suck those juices out.. also through their fangs. If someone tries getting you to hold, or sell you, a tarantula and tells you their fangs have been removed, they're lying.
