If you got bit by a tarantula you would have to do a wild dance called the tarantella. It would make the sadness go away. Tarantula bites are not harmful to man.
Scientists use tarantula venum to experiment on bugs and insects.
They would die quickly. It would take up to 3 days to kill a small bird or animal. They have round furry bodies with strong hairy legs. They molt when they get too big for their skin. In America these spiders are common.
