The Chilean rose tarantula is a large, hairy spider that is one of the most common tarantulas kept as a pet in America and Europe. It lives in the dry, scrubby high desert of northern Chile, Bolivia and Argentina. It is venomous, but its venom is not considered extremely dangerous to people.1

It lives in high desert and scrub at heights of 0 to 1,500 metres above sea level. It digs a small burrow or moves into an empty reptile or rodent burrow, lining it with silk. Many people meet it in pet shops and in home terrariums, since many wild-caught spiders are exported for the pet trade.1

何を食べるの？

It eats beetles, caterpillars, crickets, cockroaches, grasshoppers, mealworms, silkworms, waxworms, and even small lizards and rodents. It injects venom into its prey through its fangs, and the venom breaks the prey down into liquid it can absorb.1

見分け方

Its colouring is reddish or rose-coloured, and this varies between colour morphs.1
It has small, spine-like urticating hairs on its abdomen (rear body).1
It usually lives in a straight-down burrow with one or two chambers, lined with silk.1
It is usually skittish and runs away from danger rather than defending itself.1

よくまちがえられるのは： Grammostola porteri was once widely confused with this species. In 2022, the World Spider Catalog reclassified it as a junior synonym, meaning it is now treated as the same species as the Chilean rose tarantula.1

毒パワー

かむ

その毒（かむ・刺す毒）はどうなるの？

Its venom contains neurotoxins, which attack the nervous system, and hemotoxins, which disrupt the circulatory system. The venom is mainly used to hunt and digest prey. It is not considered extremely dangerous to humans.1

人にとってどれくらい危険？

人への危険: 軽いハチに刺されたくらいか、それ以下。人にはほぼ無害。

According to the available information, it is not extremely dangerous to humans. Its main hazard is its urticating hairs, which cause irritation and itching on skin and eyes. In February 2009, a British man had hairs lodged in his cornea after they were thrown from his pet while he was cleaning its tank.1

こわいとき、どうするの？

When threatened, it brushes urticating hairs off its abdomen with its legs, and it may raise its front legs and show its fangs.1

かまれたら

Medical authorities advise owners to wear protective eyewear when working near this spider, to protect the eyes from urticating hairs.1

データ

A peptide in its venom, called GsMTx4, has been shown to block mechanosensitive ion channels in living cells, which makes it useful for research.1

Its urticating hairs also act as sensors, helping it detect small vibrations and changes in pressure.1

It is probably the most common tarantula sold in American and European pet stores, largely because many wild-caught spiders are exported cheaply from Chile.1

Females can dig burrows reaching 40 centimetres deep.1

It can go without food for weeks to months, and fasting can sometimes signal that it is about to moult.1

Males grow hooked tibial hooks on their front legs while maturing, which help them hold the female during mating.1
