It is often favored by enthusiasts for its striking black coloration and docile nature, making it a popular choice for both beginner and experienced keepers. Below is a detailed description of this species:
1. Description and Appearance
-
Size: Grammostola pulchra is a large tarantula, with females growing up to 18-20 cm (7-8 inches) in leg span, while males are typically smaller, measuring around 12-14 cm (4.7-5.5 inches).
-
Coloration: One of the most distinguishing features of Grammostola pulchra is its beautiful, jet-black coloration. The body and legs are covered in dense black hairs, giving the spider a velvety appearance. The shiny black surface of the tarantula makes it look elegant and striking.
-
Legs: The legs are robust and thick, covered in long black setae (hairs). These legs contribute to the tarantula’s solid and sturdy appearance.
-
Abdomen and Carapace: The abdomen is a deep, glossy black, and the carapace (the hard, outer covering of the cephalothorax) is also black, giving the tarantula a smooth, sleek look.
2. Native Habitat and Distribution
-
Native Region: Grammostola pulchra is native to Brazil, specifically in the dry regions of the southern parts of the country. It typically inhabits forested areas with moderate humidity.
-
Habitat: This species is often found in areas with lower humidity compared to other tarantulas, preferring drier, more temperate conditions. In the wild, they may inhabit burrows or sheltered areas under rocks and logs, where they can remain relatively cool and hidden.
3. Care Requirements
Grammostola pulchra is a hardy species, making it suitable for novice tarantula keepers. Its care is relatively simple and similar to other Grammostola species.
-
Enclosure: A 10-20 gallon tank (40-75 liters) is ideal for an adult tarantula. The enclosure should have a secure lid and proper ventilation.
-
Substrate: Use a deep, moisture-retentive substrate like coconut fiber or peat moss to help maintain humidity levels. This substrate also allows the tarantula to burrow, as pulchra likes to dig.
-
Temperature: Keep the enclosure at temperatures between 24-28°C (75-82°F). This species prefers a warm environment but can tolerate cooler temperatures in the low 20s°C (68-72°F).
-
Humidity: Maintain humidity at 60-70%. It’s important not to keep the environment too wet, as Grammostola pulchra comes from relatively dry regions.
-
Water: Provide a shallow water dish and keep it clean, refilling it regularly. Mist the enclosure lightly to maintain humidity, but avoid excessive dampness.
4. Feeding
Grammostola pulchra is a carnivorous species, feeding mainly on live insects. Suitable prey includes:
-
Crickets

5. Temperament
Grammostola pulchra is known for its calm and docile nature, especially compared to other tarantula species. It is not an aggressive species, and many enthusiasts find it easy to handle. However, it is important to handle tarantulas with care and respect, as even docile species can become stressed.
-
Behavior: When threatened or provoked, Grammostola pulchra may raise its front legs and display a defensive posture, but it is unlikely to bite. It may also release urticating hairs from its abdomen as a defense mechanism, though this is rare.
-
Docility: This species is often described as one of the most docile tarantulas, making it ideal for beginners or those interested in keeping a tarantula with a calm demeanor.
