The Emperor scorpion, Pandinus imperatoris, is gaining popularity as a pet. Originating in African forests, Emperor scorpions are relatively docile and typically do no show signs of aggression unless threatened. 

Chilean rose hair tarantulas (Grammostola rosea and Grammostola portier), also referred to as Chilean fire tarantulas or just Chilean rose tarantulas are large spiders that reach a leg span of 5-6 inches. Their relatively long life spans, hardy nature, and reluctance to bite make them among the most common arachnid pets. These spiders are native to the deserts and scrubland of western South America, and are relatively recent to the pet trade, only becoming widely available in the 90s.  Males generally live 4-5 years, but females can live 15-20 years.
