What is a Goliath Birdeater Tarantula?
The Goliath Birdeater (Theraphosa blondi) is one of the largest tarantula species in the world, captivating enthusiasts with its impressive size and unique characteristics. Originating from the rainforests of South America, these arachnids are known for their formidable appearance, with leg spans that can reach up to 12 inches or more. While their name suggests a diet of birds, their primary food source in the wild consists of insects, though they will consume small vertebrates opportunistically. Their impressive size and distinct appearance have made them a sought-after pet, but potential owners should understand the responsibilities and costs associated with owning such a remarkable creature before making a purchase. This guide provides a comprehensive overview of the Goliath Birdeater’s price, helping prospective owners make informed decisions.
Goliath Birdeater Price Factors
Several factors influence the price of a Goliath Birdeater tarantula. Understanding these elements is crucial for anyone considering purchasing one. Prices can fluctuate widely based on these considerations, affecting availability and overall cost. The following sections delve into the key aspects that influence the price.
Size and Age

Generally, the size and age of the tarantula significantly impact its price. Younger tarantulas, often referred to as spiderlings or slings, are typically less expensive. As they grow, their value increases, reflecting the time and resources invested in their care. Larger, adult specimens are generally more costly due to their maturity and the longer period required to reach that stage. However, the price is not always a simple linear progression, with other factors like the tarantula’s health, morph, and origin also playing a role.
Morph and Coloration
While less common than in some other tarantula species, variations in coloration (morphs) can affect the price. Certain color patterns or unique traits may increase the value, especially if they are rare or highly sought after by collectors. Breeders sometimes specialize in specific morphs, which can also influence pricing. The appeal of specific colorations is subjective, but it remains a factor in determining the market value of the Goliath Birdeater.
Sex of the Tarantula
The sex of the Goliath Birdeater can influence its price, although the difference is usually not as significant as other factors. Females are often valued more than males because they have a longer lifespan and are capable of producing offspring. Males typically mature faster and have a shorter lifespan, making them less valuable to breeders. However, the price difference is often minimal for pet owners who are not interested in breeding their tarantulas.
Origin and Availability

The origin of the tarantula and its availability in the market significantly impact its price. Tarantulas from reputable breeders and those sourced from regions where they are legally and ethically obtained are often priced higher. The scarcity of the tarantula in a specific area can also affect the price. If a particular morph or specimen is rare or difficult to find, its price will likely be higher due to increased demand and limited supply. Always ensure that you are purchasing from a responsible source that prioritizes the welfare of the animals.
Health and Condition
The health and overall condition of the Goliath Birdeater are critical factors in determining its price. A healthy tarantula with no visible signs of disease or injury will command a higher price. Potential buyers should carefully inspect the tarantula for any signs of illness or parasites before making a purchase. Breeders and sellers should provide details about the tarantula’s feeding habits, molting history, and overall health. Always prioritize purchasing a healthy specimen to ensure its well-being and reduce potential veterinary costs.
Where to Buy a Goliath Birdeater
Finding a Goliath Birdeater requires some research, as these tarantulas are not available in every pet store. The following sources are common places to find these fascinating creatures, each with its own set of advantages and considerations.
Online Retailers

Online retailers offer a convenient way to purchase a Goliath Birdeater. They often have a wide selection and may ship directly to your location. However, it is essential to choose reputable retailers with positive reviews and a strong reputation for animal welfare. Check for guarantees of safe delivery and health. Be sure to examine photos and descriptions carefully. Verify that the retailer follows all local regulations regarding the sale and shipment of tarantulas.
Local Breeders and Pet Stores
Local breeders and pet stores offer the advantage of allowing you to see the tarantula in person before making a purchase. This allows you to assess its health and condition. Local breeders may also provide valuable insights and advice on caring for your new pet. Choosing a local breeder ensures that you have a resource nearby should any issues arise. When visiting pet stores, inquire about their tarantula sourcing practices and make sure the animals are kept in appropriate conditions. Always prioritize the ethical treatment of the animals.
Factors to Consider Before Buying
Before purchasing a Goliath Birdeater, several important factors must be considered. These considerations can help ensure that you make an informed decision and are prepared to provide appropriate care. Careful consideration can prevent buyer’s remorse and provide the best environment for the tarantula to thrive.
Legal Considerations and Regulations

Research local and national laws and regulations regarding owning a Goliath Birdeater. Some regions may require permits or have restrictions on owning exotic pets. Ensure that you comply with all applicable regulations to avoid legal issues. Be aware of any restrictions on importing or transporting the tarantula across state or international borders. Understanding and adhering to these rules is crucial for responsible ownership.
Lifespan and Care Requirements
Goliath Birdeaters have a relatively long lifespan, with females living up to 25 years or more, while males live shorter lives, around 3-5 years. Be prepared for the long-term commitment required. Understanding the specific care requirements, including housing, humidity, temperature, and feeding, is essential. Thoroughly research the species to ensure you can provide the appropriate environment and meet its needs throughout its lifespan. Failure to meet these needs could lead to health problems and a shortened life.
Cost of Ownership
Owning a Goliath Birdeater involves ongoing costs beyond the initial purchase price. Budgeting for these expenses is vital to ensure you can provide proper care.
Housing and Setup

The setup includes a secure enclosure, substrate, hides, and other essential items. The enclosure must be large enough to accommodate the tarantula as it grows, typically a large terrarium or appropriately sized enclosure. Substrate, such as coconut fiber or peat moss, is needed to maintain humidity and provide a comfortable environment. Hides and decorations are crucial to provide security for the tarantula. The cost of these items varies based on their size, quality, and materials used.
Feeding and Diet
Goliath Birdeaters eat insects, such as crickets, mealworms, and roaches. Consider the cost of providing a consistent food supply. The frequency of feeding depends on the tarantula’s age and size. You may also need to purchase supplements or vitamins to ensure the tarantula receives a balanced diet. Regular feeding and access to fresh water are crucial to maintaining a healthy tarantula.
Common Health Issues
Although Goliath Birdeaters are generally hardy, they can be susceptible to certain health issues. Ensure you can afford any veterinary care, if needed. Be prepared for potential expenses related to health concerns. Regularly monitor your tarantula for any signs of illness or stress. Having an emergency fund specifically for the animal’s health is a smart strategy.
