The Goliath birdeater ( Theraphosa blondi) is the largest spider in the world by mass, a truly impressive arachnid that captivates and intimidates in equal measure. Owning one, however, is a significant commitment. This comprehensive guide explores the intricacies of Goliath birdeater tarantula care, ensuring you're well-prepared for the responsibility.
What Do Goliath Birdeater Tarantulas Eat?
Goliath birdeaters are primarily insectivores. Their diet in the wild is incredibly diverse, encompassing a wide range of insects, small amphibians, and even the occasional small rodent or lizard. In captivity, you should feed them appropriately sized crickets, roaches (dubia roaches are a popular choice), and mealworms. The size of the prey should be no larger than the spider's abdomen. Juveniles will require smaller prey items, naturally, while adults can handle larger, more substantial meals. Remember to always provide fresh, clean water.
How Big Do Goliath Birdeater Tarantulas Get?
The Goliath birdeater's size is a major part of its appeal. Leg span can reach up to 12 inches (30 cm), with a body length of around 4-5 inches (10-13 cm). Females tend to be larger than males and have a significantly longer lifespan, often living for 15-25 years. Males, on the other hand, have a shorter lifespan of around 3-6 years after reaching maturity. Their impressive size necessitates a correspondingly large enclosure.
How Often Should I Feed My Goliath Birdeater Tarantula?
Feeding frequency depends on the spider's age and size. Young, rapidly growing spiderlings will need to be fed more frequently, perhaps every 2-3 days. Adult spiders, however, can be fed less often, typically once or twice a week. Always remove uneaten food items after 24 hours to prevent the enclosure from becoming contaminated.
What Kind of Enclosure Do Goliath Birdeater Tarantulas Need?
Given their size, Goliath birdeaters require a spacious enclosure. A minimum of a 20-gallon long terrarium is recommended for a sub-adult or adult. The enclosure should have a substrate depth of at least 6-8 inches, which is important for burrowing. A mix of peat moss and coconut fiber provides excellent moisture retention and drainage. Avoid using substrates that hold too much water, as this can lead to fungal issues. Include a shallow water dish and some hiding places, such as cork bark or half-logs, as this helps the tarantula feel secure. Proper ventilation is vital to prevent the build-up of moisture.
What Is the Best Temperature and Humidity for a Goliath Birdeater?
Maintaining the proper temperature and humidity is crucial for the health and well-being of your Goliath birdeater. The ideal temperature range is 75-85°F (24-29°C). Humidity should be kept between 70-80%. A hygrometer and thermometer are essential tools for monitoring these conditions. You can achieve this through regular misting or using a humidifier, but be careful not to over-saturate the substrate.
Are Goliath Birdeater Tarantulas Poisonous?
While Goliath birdeaters possess venom, it's considered relatively mild to humans. A bite would likely be painful, similar to a wasp sting, but rarely poses a serious medical threat. However, it's still essential to handle them with respect and care, avoiding unnecessary contact. Their primary defense mechanism is not their venom but rather the urticating hairs on their abdomen, which they flick at potential threats. These hairs can cause skin irritation, itching, and in some cases, more severe allergic reactions. Therefore, always wash your hands thoroughly after handling the enclosure.
How Much Does a Goliath Birdeater Tarantula Cost?
The cost of a Goliath birdeater can vary depending on the age, size, and vendor. Expect to pay a significant amount—this isn't a pet for those on a budget. The ongoing costs associated with providing appropriate enclosure, substrate, food, and maintaining ideal environmental conditions must also be factored in.
Conclusion
Owning a Goliath birdeater tarantula is a rewarding experience for dedicated and knowledgeable keepers. By carefully considering the specific needs outlined above and committing to responsible ownership, you can provide your Goliath birdeater with a long, healthy, and enriching life. Remember, thorough research and preparation are key to successful tarantula keeping. This detailed guide offers a solid foundation, but continuous learning is crucial for providing the best possible care for this incredible creature.
