Range & Habitat
Grassland areas of Brazil and Uruguay.
Hair covers the entire body of tarantulas; it is their most important means of sensory input and serves several functions. Some hairs contain temperature or smell receptors. Other hairs can detect airborne vibration. Barbed hairs called urticating hairs, mostly on the abdomen, can be "flicked" and act as an itchy irritant. These specialized hairs are only present on New World tarantulas.
Rose Hairs are docile and rarely bite but like other tarantulas, do have a small amount of venom and the effects on people vary. There has never been a known death from a tarantula bite. These spiders are solitary animals, coming out at night to hunt for prey or a mate.
Tarantulas have two pairs of booklungs (most spiders have only one pair). They do not build webs, but instead use their silk to build nests and vibration triggers for hunting prey. Tarantula legs are made up seven parts plus a claw. They have the ability to regenerate a lost leg during a molt. Unfortunately males only molt once, prior to sexual maturity. Bald spots are common and will be replaced with the next molt. These are very common tarantulas in the pet trade.
Reproduction & Growth
Rose hair tarantulas are found in deserts and scrub lands of Bolivia, Argentina, and Chile. Females can reach up to 5-inch leg span, the males slightly less.
In the Wild: Insects and other arthropods. Occasionally, small animals. In the Zoo: Crickets.
