Massive Strength and Dark Hues – The Second Giant

Theraphosa stirmi, originating from the humid rainforests of Guyana and Brazil, is another giant tarantula, closely related to Theraphosa blondi. Known as the Burgundy Goliath Birdeater or T. stirmi, it is considered one of the largest spiders on Earth, second in size only to T. blondi. It is a powerful and majestic tarantula, whose keeping is a dream for many advanced enthusiasts. This species is intended for experienced keepers, due to its size and specific requirements.

Natural Habitat and Geographical Origin

T. stirmi inhabits the humid tropical forests of Guyana and northern Brazil. It leads a terrestrial lifestyle, digging deep and extensive burrows in the ground or occupying abandoned burrows of other animals. Its environment is characterized by very high humidity and stable, warm temperatures.

Morphology and Size

Adult Theraphosa stirmi specimens reach a leg span of 22-28 cm (9-11 inches). Their body is massive, covered with dense, long hairs in shades of dark brown, burgundy, or deep black. Unlike T. blondi, T. stirmi often has more uniform coloration, sometimes with a delicate burgundy sheen, especially on the legs. It is a true colossus that makes a huge impression with its size and powerful build.

Behavior and Temperament

T. stirmi is generally a species with a moderately calm temperament, but due to its size and mass, it can be very defensive. Like other New World tarantulas, it can kick urticating hairs from its abdomen, which are very irritating and can cause severe itching and respiratory irritation. In a threat situation, it can also produce loud hissing sounds (stridulation) by rubbing its chelicerae and legs together. Bites are rare, and their venom is mild and does not pose a serious medical threat to humans, comparable to a wasp sting; however, due to the size of the chelicerae, a bite is painful.

Feeding Habits

In nature, their diet consists of large insects, lizards, frogs, and even small rodents and birds. In captivity, adult specimens can be fed large crickets, cockroaches, locusts, and occasionally even pinky mice or small chicks. It is important not to overfeed the spider. Feeding once every 1-2 weeks is recommended.

Lifespan

Female Theraphosa stirmi are long-lived and can live from 15 to 20 years under optimal breeding conditions. Males have a significantly shorter lifespan, typically 3 to 5 years.

Housing Requirements

Terrarium: For an adult specimen, a very spacious terrarium measuring at least 50x40x40 cm is required. Excellent ventilation is crucial.

Substrate: A very deep layer of substrate (at least 20-25 cm), such as coco fiber or a mixture of peat and vermiculite, should be placed at the bottom of the terrarium, which retains moisture well and allows for digging.

Temperature: The ideal temperature is 24 to 28°C.

Humidity: The recommended humidity is 80-90%. This can be maintained by daily misting of the terrarium and providing constant access to a large water dish.

Hideout: A stable, solid hideout (e.g., a large piece of bark, a ceramic cave) should be provided to give the spider a sense of security.

Water: A large, shallow water dish should always be available and refilled regularly.

Suitable for Hobbyists

Theraphosa stirmi is a species intended for experienced keepers. Its specific humidity requirements, sensitivity to stress, as well as its size and potential defensive strength, mean that it is not a species for beginners. It requires regular attention and an appropriate environment.

Why Choose This Species?

If you are an experienced keeper looking for one of the largest spiders on Earth, with a majestic presence and dark, burgundy coloration, the Burgundy Goliath Birdeater is an excellent choice. Its impressive size and power make it one of the most fascinating and desirable species for observation.

The Amazon's Arboreal Jewel – Spectacular Colors and Sensitivity

Ybyrapora diversipes, formerly known as Avicularia diversipes, is one of the most colorful and sought-after arboreal tarantulas from Brazil. Known as the Brazilian Colorful Tarantula or Y. diversipes, it stands out with its remarkable variation in coloration depending on the developmental stage, from metallic greens and blues in juveniles to oranges, reds, and purples in adults. This species has a moderate speed and delicate nature, making it suitable for intermediate and experienced keepers.

Natural Habitat and Geographic Origin

Y. diversipes inhabits the humid rainforests of eastern Brazil, particularly the regions of Espírito Santo and Bahia. It leads a typical arboreal lifestyle, building its web tunnels and nests on branches, leaves, and in tree crevices, perfectly camouflaging itself among the vegetation.

Morphology and Size

Adult Ybyrapora diversipes specimens reach a leg span of up to 12-14 cm (4.5-5.5 inches). The coloration is incredibly variable: juveniles are often metallic green or blue, while adults display a wealth of colors, including a red-orange abdomen with a black stripe, bluish-green legs with orange tips, and pink or purple accents. It is a true "chameleon" among tarantulas.

Behavior and Temperament

Y. diversipes is a species with moderate speed and generally a milder temperament, although it is timid. When threatened, it first tries to flee, and then may spray a stream of feces towards the intruder. It rarely attempts to bite. Its venom is mild and poses no serious medical threat to humans, comparable to a bee sting. It does not possess urticating hairs. Due to its delicate nature, handling should be done with caution.

Feeding Habits

In nature, their diet consists of insects and other small invertebrates they hunt in the treetops. In home husbandry, they should be fed appropriately sized feeder insects, such as crickets, cockroaches (e.g., Turkish, Argentine), or fruit flies for juveniles. Feeding 1-2 times a week is recommended.

Lifespan

Female Ybyrapora diversipes have a moderate lifespan and can live from 8 to 12 years under proper husbandry conditions. Males have a significantly shorter lifespan, typically 2 to 4 years.

Husbandry Requirements

Terrarium: Due to its arboreal lifestyle, a tall terrarium (so-called "arboreal") measuring at least 20x20x30 cm for juveniles and 30x30x45 cm or more for adults is necessary. Excellent ventilation and high humidity are crucial.

Decor: Numerous branches, pieces of bark, vines, and artificial plants should be provided to serve as platforms for nest building and hiding.
