Also known as the Chilean Rose Hair Tarantula, common among Tarantula-admirers as a pet, this New World Species is rather calm compared to most Tarantulas. This particular Tarantula has what many other New World Tarantulas have, Urticating hairs/bristles. This means that the many hairs that cover this tarantula's whole body can be flung off and are barbed so that they stick into oncoming threats including humans. (From personal experience, these hairs can be very irritating on skin, I recommend being cautious around these spiders even if they are a pet.) Despite these annoying hairs, these spiders don't have a toxic venom, and are not remotely threatening to humans in any way. However these Tarantulas are often caught and fried in some south American countries, and treated as a common snack. But if not captured to this unfortunate death, the females of this species can live over 20 years, although the males usually only make it to 5 years before their "partner" eats them after mating. Rose Hairs are good eaters, eating various insects, other spiders, some scorpions, lizards, frogs, and small mammals. These spiders don't have the largest leg span, usually only reaching a max of 15.24 cm (6 inches), they are considerably dense and heavy compared to other spiders, making them some of the heaviest in the world.
