Brazilian Black

Grammostola pulchra

Also known as Brazilian Black Tarantula, Uruguayan Black Tarantula

Brazilian black tarantulas are renowned for their velvety, pitch-black coloration and famously calm temperament, making them long-lived favorites among arachnid enthusiasts. Native to the grassland and forest regions of southern Brazil and Uruguay, these terrestrial spiders spend their days burrowed beneath leaf litter or occupying abandoned rodent burrows. Slow to mature, females can survive for over twenty years while serving as important generalist predators of insects and small invertebrates.
