Part of the larger species of arachnids, 900 species of them have been
verified. The male in this species is generally smaller than the female, and mating involves the death and/or consumption of the male by the female. These large arachnids can consume smaller reptiles, birds, and large insects. The normal lifespan of these spiders can span for 20 years. Their anatomy consists of an exoskeleton which can characterize the arthropoda species itself. They can have up to 1000 offspring at once so extinction is not a problem for this species.

Spiders breathe through minuscule pores on their legs that allow air into the body. The oxygen is then evenly distributed. Tarantulas can also mouth breathe if necessary, since loss of legs is common during shedding. This is a talent unique to tarantulas only and not other spiders. Spiders have different types of respiratory systems. Some have book lungs, some have tubular tracheae, and others have both tracheae and book lungs. Book lungs are located by two hairless patches on the underside of the spider's abdomen. Each lung has an open slit for air intact and a stack of leafletlike, blood filled structures called lamellae. As air passes into the spider's body, blood passing through the lamellae is oxygenated.
