The Texas Brown Tarantula, scientifically known as Aphonopelma hentzi, is a species of tarantula native to southern parts of the United States, particularly Texas, Oklahoma, Kansas, and Missouri. It is a large, docile tarantula with a unique set of characteristics and behaviors that make it a fascinating creature to study and keep as a pet.
The Texas Brown Tarantula is one of the largest tarantula species in North America, with a body length ranging from 2 to 2.5 inches and a leg span that can reach up to 5 inches. The coloration of the adults varies, with males typically having dark brown bodies and legs, while females are more reddish-brown in appearance. They have eight eyes arranged in two rows and fangs used for injecting venom into their prey.
These tarantulas have specialized hairs called urticating hairs on their abdomens. When threatened, they can kick these hairs into the air as a defense mechanism. These hairs can cause irritation to predators, including humans, causing discomfort and itching. Therefore, it is important to handle them with care and avoid contact with these hairs.
The Texas Brown Tarantula is generally a calm and docile species. They prefer to avoid conflict and will retreat if given the opportunity. When threatened, their primary defense mechanism is to raise their front legs and expose their fangs as a warning. Biting is rare but may occur if they feel severely threatened or cornered. Their venom is not known to be dangerous to humans, but it can cause mild pain and swelling.
These tarantulas are mainly nocturnal, spending the day in burrows they dig themselves or seek out abandoned burrows or natural crevices. At night, they emerge to hunt for prey such as insects and small vertebrates. They are solitary creatures and only come together for breeding purposes.
The Texas Brown Tarantula is indigenous to the southern regions of the United States, particularly Texas, Oklahoma, Kansas, and Missouri. It is adapted to the dry, arid climate of these regions and can be found in grasslands, prairies, and scrublands.
The natural habitat of the Texas Brown Tarantula is diverse, ranging from deserts and grasslands to forests and scrublands. They can be found in a variety of habitats, including open plains, rocky areas, and burrows. These tarantulas dig burrows using their fangs and legs, creating tunnels that provide protection from predators and extreme weather conditions.
They are often found in areas with loose soil or sandy substrate, as it allows them to dig more easily. The burrows can extend several feet underground and have a webbed entrance to detect prey and intruders. These tarantulas also construct silk-lined chambers within their burrows for molting, mating, and resting.
Keeping a Texas Brown Tarantula as a pet requires careful consideration and attention to their specific needs. It is essential to provide them with an appropriate enclosure that mimics their natural habitat. A terrarium with a secure lid and sufficient ventilation is recommended. The size of the enclosure should be suitable for the tarantula’s size, providing enough space for them to move around and create burrows.
The substrate in the enclosure should consist of a mixture of coconut fiber and potting soil, providing a moist environment while allowing for proper drainage. Decorations such as rocks, bark, and fake plants can be added to create a more naturalistic habitat. Temperature and humidity should be maintained within the recommended range, typically around 70-85°F with a humidity level of around 60-70%.
Feeding tarantulas requires providing them with a diet of live insects, such as crickets, cockroaches, and mealworms. The size of the prey should be suitable for the tarantula’s size, and it is recommended to feed them 2-3 times a week. Fresh water should always be available in a shallow dish, and the enclosure should be cleaned regularly to maintain hygiene.
Health & Diseases
The Texas Brown Tarantula is generally a hardy species, but they can be susceptible to certain health issues if not provided with proper care. One common problem is dehydration, as they require a moist environment with access to fresh water. Insufficient humidity can lead to the tarantula losing its ability to molt successfully or developing respiratory problems.
Another common health issue is injury or trauma from falling or being dropped. Tarantulas are delicate creatures, and any fall or impact can result in serious injuries. It is important to handle them gently and with care to avoid causing harm.
When it comes to diseases, tarantulas can be affected by various parasites, fungi, or bacterial infections. Symptoms of illness may include lethargy, loss of appetite, changes in coloration, or abnormal behavior. If any signs of illness are observed, it is recommended to consult a veterinarian experienced in exotic animal care.
Diet and Feeding
The diet of the Texas Brown Tarantula primarily consists of insects and other small invertebrates. In the wild, they hunt for prey at night, using their keen sense of touch and sophisticated set of fangs to capture and immobilize their victims. They are opportunistic hunters and can consume a wide range of prey items, including crickets, grasshoppers, beetles, and small spiders.
When kept as pets, they can be fed live insects such as crickets or cockroaches. The size of the prey should be appropriate for the size of the tarantula. It is important to ensure that the prey is clean and free from pesticides or other harmful substances. Feeding should be done in a separate container to prevent any substrate from being ingested along with the prey.
Young tarantulas should be fed more frequently, typically 2-3 times a week, while adults can be fed once or twice a week. It is important not to overfeed, as this can lead to obesity and health problems. Water should always be available in a shallow dish or through misting the enclosure to maintain proper hydration.
The breeding season for Texas Brown Tarantulas usually occurs from late summer to early fall. During this time, mature males will venture out in search of females, often covering long distances to find potential mates. The male initiates courtship by tapping on the female’s burrow or vibrating the ground nearby to signal his presence.
If the female is receptive, she may emerge from her burrow, and the male will approach her cautiously, using his pedipalps to transfer a sperm packet called a spermatophore. The female, once inseminated, stores the sperm for future egg fertilization. The male’s lifespan may end shortly after mating, as they often become the female’s next meal.
The female Texas Brown Tarantula constructs an egg sac from silk within her burrow. She guards and cares for the sac, ensuring that it remains protected from predators and environmental conditions. After a few weeks, the eggs will hatch into spiderlings, miniature versions of the adults. The spiderlings will remain with the female for a period of time before dispersing and beginning their independent lives.
