Tarantulas make interesting pets and can be useful as well.
They have been placed in windows to keep unwanted people away such as the jewelry storeowner who was robbed many times. He purchased a tarantula to keep in his display case at night and he hasn't been robbed since. Many people believe that tarantulas are deadly poisonous. This is not so. The tarantula secretes a fluid through the salivary glands, which is injected into its prey using their fangs.
