Avicularia braunshauseni, discovered in Brazil in 1999, belongs to a class of tarantulas that are known as "pinktoes" because of their characteristically colored foot pads. Avicularia tarantulas are not considered to be aggressive. They prefer to jump and flee as quickly as possible when threatened. They'll occasionally respond to a threat by launching a jet of excrement that can accurately hit a target 3 feet (1 meter) away.
