Theraphosa blondi, originating from the humid rainforests of South America, is undoubtedly the most famous and admired tarantula in the world. Known as the Goliath Birdeater or T. blondi, it is recognized as the largest spider on Earth by mass. It is a true giant, whose impressive size and majestic presence make it a dream for many keepers. This species is intended for experienced breeders who can meet its specific requirements.

T. blondi inhabits the humid tropical forests of French Guiana, Suriname, Guyana, southern Venezuela, 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.

Adult Theraphosa blondi individuals reach a leg span of up to 25-30 cm (10-12 inches), and their body mass can exceed 170 grams. Their body is massive, covered with dense, long hairs in shades of brown, from light brown to dark brown. Young individuals are lighter, and their coloration darkens with age. It is a true colossus that makes a huge impression with its size and powerful build.

T. blondi 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 threatening 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 its fangs, a bite is painful.

In nature, their diet consists of large insects, lizards, frogs, and even small rodents and birds. In captivity, adult individuals 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.

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

Terrarium: For an adult individual, a very spacious terrarium with dimensions of 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. This substrate should retain moisture well and allow 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. Hide: A permanent, sturdy hide (e.g., a large piece of bark, 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.

Theraphosa blondi is a species intended for experienced keepers. Its specific humidity requirements, sensitivity to stress, as well as its size and potential defensive strength, make it unsuitable for beginners. It requires regular attention and an appropriate environment.
