Mexican Redknee Tarantula

The Mexican redknee tarantula is a large, striking ground-dwelling tarantula native to the Pacific coastal regions of Mexico, particularly the states of Jalisco, Colima, Michoacán, and Guerrero. It is instantly recognizable by its jet-black body and legs contrasted with bold orange-red bands at each leg joint, a coloration that made it one of the most popular tarantulas in the pet trade and a frequent subject of nature documentaries.

Like other New World tarantulas, this species digs or adopts a burrow in the ground, often at the base of vegetation or in rocky, well-drained soil of tropical dry forest and thorn scrub habitat. It is a relatively slow-moving, docile spider by tarantula standards, relying primarily on camouflage and a defensive display, including flicking urticating (barbed, irritating) hairs from its abdomen with its hind legs, rather than aggression, to deter potential predators.

Once heavily collected from the wild for the pet trade, wild populations of the Mexican redknee tarantula are now protected, and most individuals in captivity today are captive-bred. In the wild, it remains an important predator of insects and other small animals within its dry forest habitat.

• Jet-black body and legs with vivid orange to reddish bands at each leg joint
• Large, robust, hairy body typical of tarantulas, with a dense covering of setae (hairs) on the abdomen
• Relatively slow, deliberate movements compared to many other spiders
• Defensive posture includes rearing up and rapidly brushing hind legs across the abdomen to flick loose urticating hairs
• Lookalikes: other Brachypelma species (similar banding pattern, subtle differences in leg coloration and hair density)

Native to a narrow band of Pacific coastal Mexico, including tropical dry forest and thorn scrub in Jalisco, Colima, Michoacán, and Guerrero. It lives in burrows in the ground, often reusing rodent burrows or excavating its own beneath rocks, roots, or dense vegetation, in areas with a pronounced dry season followed by seasonal rains.

This tarantula is a nocturnal, sit-and-wait predator that spends most of the day within its burrow, emerging at night to hunt near the entrance or wait for prey to pass. Diet consists of insects, other arthropods, and occasionally small vertebrates such as lizards. When threatened, it typically prefers to retreat into its burrow, but if cornered it may rear up in a defensive posture and flick barbed urticating hairs from its abdomen toward the source of the disturbance rather than fleeing or biting.

After mating, females produce a large silken egg sac containing several hundred eggs, which they guard closely within the burrow. Spiderlings emerge after several weeks and disperse to dig their own small burrows nearby. Like most tarantulas, this species grows slowly, molting periodically over several years before reaching maturity, with females taking considerably longer to mature than males and living significantly longer, with some females documented living two to three decades in captivity.
