The Mexican Redknee Tarantula, scientifically known as Brachypelma smithi, is one of the most popular tarantula species kept as pets due to its striking appearance and relatively docile nature. But when it comes to understanding its classification, many enthusiasts and pet owners wonder: is the Mexican Redknee Tarantula a New World tarantula? The answer is yes, and in this article, we will dive deep into why that is, along with other fascinating facts about this species.
Understanding New World and Old World Tarantulas
Before we get into the specifics of the Mexican Redknee Tarantula, it’s important to know what “New World” and “Old World” refer to in the context of tarantulas.
New World Tarantulas: These species are native to the Americas, specifically North, Central, and South America. They tend to be more docile and have urticating hairs (small, stinging hairs) on their abdomen that they use as a defense mechanism when threatened. New World tarantulas are also typically less aggressive than their Old World counterparts.
Old World Tarantulas: These tarantulas come from Africa, Asia, and the Middle East. They are often more defensive and can be quicker to bite. Unlike New World species, Old World tarantulas do not have urticating hairs. Instead, they rely on other defense strategies like venomous bites.
Why is the Mexican Redknee Tarantula a New World Tarantula?
The Mexican Redknee Tarantula is classified as a New World species for several key reasons:
1. Native Habitat
As the name suggests, the Mexican Redknee Tarantula is found in Mexico, specifically in the western parts of the country. Its natural habitat includes dry, arid regions, often around scrubby forests and rocky areas. The tarantula’s habitat in Mexico places it firmly in the New World category, as it is native to the Americas.
2. Urticating Hairs
One of the defining characteristics of New World tarantulas is the presence of urticating hairs. The Mexican Redknee, like other New World species, has these specialized hairs on its abdomen. When the tarantula feels threatened, it rubs its abdomen with its back legs, causing the hairs to be released into the air. These hairs are irritating to the skin and eyes of potential predators, serving as a defensive mechanism.
3. Temperament
New World tarantulas are generally more docile and less aggressive than Old World species, and the Mexican Redknee is no exception. While it may show some defensive behavior if disturbed, it is generally considered a calm and non-aggressive tarantula. This trait is a hallmark of New World tarantulas, which often prefer to retreat into their burrows rather than confront threats head-on.
Key Characteristics of the Mexican Redknee Tarantula
Now that we know that the Mexican Redknee Tarantula is classified as a New World species, let’s take a closer look at its unique traits.
1. Appearance
The Mexican Redknee Tarantula is known for its striking and beautiful appearance. The body of the tarantula is typically a dark brown or black color, while the legs are marked with bright orange or red patches. These vivid red markings on the knees and other parts of the legs give the tarantula its name. This striking coloration makes the Mexican Redknee a favorite among collectors and enthusiasts.
2. Size
Mexican Redknee Tarantulas are considered medium to large tarantulas. Females can reach a leg span of up to 6 inches (15 cm), while males are generally smaller, with a leg span of about 4.5 inches (11.5 cm). Despite their size, they are relatively slow-moving, which is another reason why they are popular pets for both beginners and experienced keepers.
3. Longevity
One of the appealing aspects of owning a Mexican Redknee Tarantula is their long lifespan. Females can live up to 30 years in captivity, while males generally live much shorter lives, around 5 to 10 years. This longevity makes them an excellent choice for those looking for a long-term pet.
4. Diet
Like most tarantulas, the Mexican Redknee is a carnivorous predator. It primarily feeds on insects, including crickets, cockroaches, and mealworms. In the wild, it may also prey on small vertebrates like lizards and frogs. Tarantulas catch their prey using their venomous fangs, which paralyze and immobilize their food. They then use digestive enzymes to liquefy the prey’s insides before sucking up the liquid meal.
The Role of the Mexican Redknee Tarantula in the Ecosystem
In its native habitat, the Mexican Redknee Tarantula plays an important role in controlling the population of insects and small animals. By feeding on a variety of prey, it helps maintain a balanced ecosystem. Tarantulas are also an important food source for other animals, such as birds, reptiles, and mammals, helping sustain the food chain.
Care Requirements for the Mexican Redknee Tarantula
For those interested in keeping a Mexican Redknee as a pet, it’s important to understand the specific care requirements to keep them healthy and happy.
1. Enclosure
The Mexican Redknee Tarantula requires a spacious enclosure to accommodate its size and natural behavior. A tank that is at least 10 gallons in size is recommended for an adult, with a secure lid to prevent escape. The enclosure should have a substrate like coconut fiber or peat moss to allow for burrowing, as these tarantulas are known to create burrows in the wild.
2. Temperature and Humidity
Since the Mexican Redknee is native to dry, arid regions, it prefers a relatively warm environment. The ideal temperature range is between 75°F to 85°F (24°C to 29°C). However, humidity should be kept low to moderate, around 60%. It’s important not to let the substrate become too damp, as excessive moisture can lead to mold growth and health issues for the tarantula.
3. Diet
In captivity, the Mexican Redknee should be fed a diet of live insects. Appropriate prey includes crickets, roaches, and mealworms. It’s important to provide a variety of insects to ensure the tarantula receives all the necessary nutrients. Feedings should occur once a week for adults, with younger tarantulas requiring more frequent meals.
4. Water
Though the Mexican Redknee is adapted to dry conditions, it still requires access to clean water. A shallow water dish should be placed in the enclosure and changed regularly. It’s important to ensure that the water dish is not too deep to prevent drowning.
5. Handling
While the Mexican Redknee is generally considered docile, it is best to avoid excessive handling. Tarantulas, like all animals, can become stressed from too much interaction. It’s important to let your tarantula explore its environment without constant disturbance.
Common Health Issues
Though hardy, the Mexican Redknee Tarantula can face certain health challenges in captivity. Here are some common issues to look out for:
Molt Problems: Tarantulas periodically shed their exoskeleton, a process known as molting. If a tarantula has difficulty molting, it may need assistance to avoid injury or death.
Dehydration: Lack of water or overly dry conditions can lead to dehydration. Ensure that the tarantula has constant access to fresh water and that the humidity levels are appropriate.
Pests: Sometimes, mites or other pests can infest a tarantula’s enclosure, leading to skin irritation. Regular cleaning of the tank and monitoring for pests can prevent this issue.
Conservation Status
The Mexican Redknee Tarantula is listed as “Near Threatened” on the International Union for Conservation of Nature (IUCN) Red List. The primary threat to its survival comes from habitat loss due to urbanization and illegal collection for the pet trade. However, there are ongoing conservation efforts to protect their natural habitats and prevent over-exploitation.
Conclusion
In summary, the Mexican Redknee Tarantula is indeed a New World species, with key features that define its classification, such as its native habitat in Mexico, its possession of urticating hairs, and its docile temperament. These fascinating creatures make excellent pets for tarantula enthusiasts, especially those new to keeping tarantulas. With proper care, they can live long, healthy lives and continue to captivate their owners with their beauty and unique behaviors.
