I would rather spend time studying a spider because most people thinks its harmful to us even though its harmless. Its bite is harmless but it hurts. The tarantula has been a popular pet. Periodically shed their external skeletons that is called molting. In this process they replace internal organs, such as female gentiles, and even regrow lost appendages. I don't like the wasp because i just don't, and the tarantula is cooler.
