Brachypelma smithi, is a terrestrial tarantula native to the western faces of the Sierra Madre Occidental and Sierra Madre del Sur mountain ranges in Mexico. They are a large species, and are a popular choice for enthusiasts.
The red knee tarantula inhabits the complex scrub-forest habitat and semi-desert regions where there is an abundance of food. The red knee tarantula needs to burrow and so is rarely found on rock faces.
The Red Knee tarantula is found in Mexico, south-western United States and Panama. They are quite common now to be kept as pets as they are slow growers and they have a beautiful body in colour and shape. The red knee tarantula also has a bite that could hurt a human but would not be harmful. The red knee tarantula typically grows to around 20cm in length but some red knee tarantula individuals have known to become much bigger.
The red knee tarantula has a relatively long lifespan for a spider as many get to be older than 30 years of age. The female red knee tarantula is often bigger than the male red knee tarantula and the female red knee tarantula also tends to be more aggressive. Female red knee tarantulas tend to live longer than the smaller male red knee tarantula due to the fact that they have a more fierce temperament.
