Texas Brown Tarantula

Fascinating facts about the Texas Brown Tarantula

• Adult Texas brown tarantulas can reach a leg span beyond 10 cm and weigh more than 85 g. Their bodies are dark brown, though individual shades can vary, and the colours become especially vivid after a molt, with males recognisable by black legs and a copper-coloured carapace.
• When disturbed, A. hentzi adopts a defensive stance by lifting onto its hind legs and raising its front legs in a classic warning pose. Though generally docile, it can also flick small, coarse urticating hairs from its abdomen toward the perceived threat. This combination of visual threat and irritating hairs deters predators without the need for aggression.
• Females of this species have been recorded living up to 40 years, although no study has followed an individual that long, so they may survive even longer. In contrast, males rarely survive more than a year after reaching maturity. This disparity means that females spend most of their lives in burrows, while males have a brief adult phase focused on finding mates.
• Male Texas brown tarantulas leave their burrows in the autumn to seek out females. They wander across the ground rather than staying hidden, exposing themselves to a range of habitats. Researchers have recorded individuals travelling as far as 1.7 km, demonstrating a remarkable willingness to move far from home. Such long journeys boost the odds of finding a receptive female that remains in a burrow.
• The Texas brown tarantula often co-habits its underground shelter with narrow-mouthed toads (Gastrophryne spp). The toads gain safety from predators such as snakes while the spider benefits because the amphibians eat small invertebrates that might otherwise prey on newly hatched spiderlings. The toads ignore the fresh spiderlings, so the young are protected from those tiny predators. This arrangement appears to be a mutualism, giving both species a clear advantage.
