Physical Characteristics
The Goliath birdeater tarantula is known for its physical characteristics, such as its large size, hairy body, and brown coloration. It is the largest spider species in the world by mass and body length, with females reaching a weight of 175 grams, a body size of 5.1 inches, and a leg span of 11 inches.
Spiderlings grow up to 4 inches per year until maturity. This species has thick, hairy exoskeletons that come in shades of brown. The males have a shorter lifespan of 3 to 6 years, while females can live for 15 to 25 years.
Reproduction in captivity is difficult due to the female’s selectiveness and territorial behavior. The Goliath birdeater tarantula is truly a remarkable creature, both in terms of its size and appearance.
Natural Habitat
Originating from the northern regions of South America, this colossal arachnid thrives in warm and densely vegetated environments. The natural habitat of the Goliath birdeater tarantula provides various threats to its survival.
One of the main threats is habitat loss due to deforestation and urbanization. As the tarantula relies on dense vegetation for shelter and hunting grounds, the destruction of its natural habitat poses a significant risk to its population.
Additionally, the tarantula faces predation from other animals such as birds, reptiles, and mammals.
Conservation efforts for the Goliath birdeater tarantula are limited due to its aggressive nature and difficulties in breeding in captivity. However, raising awareness about the importance of preserving its habitat and implementing measures to protect these areas are crucial steps in ensuring the long-term survival of this remarkable species.
Behavior and Hunting
Behavior and hunting patterns of the Goliath birdeater tarantula are characterized by its aggressive nature, nocturnal activity, and reliance on its urticating hairs and venom to defend against predators and capture prey. The Goliath birdeater tarantula employs unique hunting techniques to secure its meals. It uses its large fangs and two appendages called chelicerae and pedipalps to deliver a venomous bite to immobilize its prey. Additionally, it possesses stinging, barbed bristles called urticating hairs, which it flicks at potential threats, causing irritation and pain. To handle its aggression, it is best to avoid handling the Goliath birdeater tarantula altogether due to its fast movement and ability to inflict severe pain with its urticating hairs. When encountering aggression, it is important to give the tarantula space and avoid provoking it further. Understanding the Goliath birdeater tarantula’s behavior and employing appropriate strategies for handling aggression is essential for the successful care of this unique species.

| Nocturnal | Urticating Hairs |
Venom and Defense Mechanisms
Venom and defense mechanisms of the Goliath birdeater tarantula are crucial for its survival and protection against predators and potential threats.
The venom of the Goliath birdeater is not lethal to humans, causing pain similar to a bee sting. However, it is an effective deterrent against potential predators.
In addition to venom, the tarantula possesses other defense mechanisms. It has stinging, barbed bristles called urticating hairs that it flicks off when threatened. These hairs can cause rashes, blisters, and discomfort to predators.
The Goliath birdeater tarantula also utilizes stridulation, a technique where it rubs its legs or fangs together to produce a hissing sound, effectively warning off potential threats.
Given its aggressive nature and ability to inflict severe pain with its urticating hairs, handling precautions should be taken when dealing with this species. It is best to avoid handling altogether.
Furthermore, the Goliath birdeater tarantula holds cultural significance as it is considered a delicacy in certain parts of northeastern South America.
Life Cycle and Lifespan
The life cycle of this remarkable creature unfolds over several years, showcasing the marvel of nature’s intricate design and the fleeting beauty of existence.
- Spiderling growth rate:
- Goliath birdeater tarantulas start their life as spiderlings and grow rapidly, reaching sizes of up to 4 inches per year until they reach maturity. This fast growth rate is essential for survival in the wild, as it allows them to quickly develop the size and strength needed to defend themselves and secure food.
- Handling and safety precautions:
- Handling these tarantulas is not recommended due to their aggressive nature, fast movement, and ability to inflict severe pain with their urticating hairs. It is important to prioritize safety when interacting with these spiders and avoid any unnecessary risks. Instead, observe them from a safe distance and provide them with the appropriate care in their enclosure. This will ensure the well-being of both the tarantula and the keeper.
Terrarium Setup and Requirements
Terrarium setup and requirements for the Goliath birdeater tarantula emphasize the need for a spacious 30-gallon or larger enclosure with a deep substrate layer, a water bowl, and specific temperature and humidity levels to create a suitable environment for this terrestrial species. The large enclosure size allows ample space for the tarantula to move around and burrow. The substrate layer should be deep enough to accommodate burrowing behavior and can consist of a mixture of peat moss, vermiculite, and coconut fiber. This creates a moist and naturalistic environment. Additionally, terrarium decorations such as hollow logs, bark, and live plants can provide hiding spots and enrichment for the tarantula. Temperature and humidity control are crucial for the well-being of the Goliath birdeater tarantula. The terrarium should be maintained at temperatures between 75 and 82°F, with a humidity level of around 80%. This can be achieved by using a combination of under-tank heating pads, ceramic heat emitters, and misting the substrate regularly. To highlight the requirements for terrarium setup and temperature and humidity control, the following table illustrates the ideal conditions for the Goliath birdeater tarantula:
| Terrarium Setup and Requirements |
|---|
| Spacious 30-gallon or larger enclosure |
| Deep substrate layer of peat moss, vermiculite, and coconut fiber |
| Terrarium decorations such as hollow logs, bark, and live plants |
| Temperature: 75-82°F |
| Humidity: around 80% |
| Use under-tank heating pads and ceramic heat emitters |
| Regularly mist the substrate |
| Provide a water bowl for drinking and humidity maintenance |
Feeding and Nutrition
Feeding and nutrition are essential aspects of maintaining the well-being and vitality of the Goliath birdeater tarantula in captivity. These spiders are nocturnal hunters, and their feeding frequency should mimic their natural behavior.
It is recommended to feed adult Goliath birdeaters once or twice a week, while spiderlings should be fed more frequently to support their rapid growth.
When it comes to prey selection, Goliath birdeaters are opportunistic predators and will consume a variety of live insects, including crickets, roaches, and mealworms. It is important to provide appropriately sized prey that is smaller than the spider’s body length to avoid any potential injuries.
It is also crucial to remove any uneaten prey from the enclosure the following morning to prevent the prey from causing harm to the tarantula during molting.
Common Health Issues
Common health issues that may affect the Goliath birdeater tarantula include dehydration, molting problems, mold or fungus outbreaks, and mites.
Dehydration is a significant concern for these spiders, and symptoms include lethargy, a shriveled abdomen, and a hunched appearance. To prevent dehydration, it is crucial to maintain moderate to high humidity levels and spray the substrate frequently. In cases of severe dehydration, tarantulas should be moved to a humid container with moist paper towel and a water dish.
Molting problems can occur when the enclosure is not humid enough. To prevent such issues, humidity levels should be kept above 75%, and the substrate should be sprayed daily while ensuring the water bowl is topped up.
Mold or fungus outbreaks can infect internal organs and cause life-threatening complications. Regular spot cleaning and adequate cross-ventilation can help prevent these outbreaks.
Mites are often present in tarantula enclosures and can cause distress if their population becomes abundant. To keep mite populations in check, it is essential to clean up waste and leftovers regularly.
Breeding in captivity is difficult due to the female’s selectiveness and territorial behavior.
