Description
Listed here is a Grammostola grossa juvenile female tarantula. Commonly known as the Guarani giant tarantula, G. grossa, like many of its close cousins, is found in the subtropical savanna grasslands of Brazil, Paraguay, Uruguay and northern Argentina. Grossa (Lat. grossus) refers to large size or bulk. Guarani in the common name refers to the indigenous people of the region.
Along with G. pulchra, G. pulchripes, A. chalcodes and T. albopilosus, the Guarani giant tarantula is worthy of consideration as a first tarantula. Medium large in size, females may attain 7 inches. Color pattern is metallic copper, bronze and dark brown, with a conspicuous iridescent mirror patch on the dorsal abdomen. Although imposing in size, disposition is gentle. Larger specimens in particular show economy of movement. Steps are slow and deliberate, except of course when it’s time to ambush prey.
It took 3 years for this female to reach this size. It will take a few more years for her to reach adulthood. On the other hand she will live upwards of 25 years with good care. G. grossa is low maintenance and exceptionally hardy. An added plus is they are drought tolerant.
For juveniles and older specimens, such as that listed here, we use slightly dry substrate and keep humidity only a bit higher than that of typical room air. Room temperature (68-72F) is fine with growth faster towards 80-85F. A water dish can be useful to ensure against dehydration, especially if ventilation is liberal.

Care highlights:
- slightly dry to dry substrate for juveniles and older
- water and ventilate to achieve a dry to slightly humid environment
- room temperature (68-72F) up to 80-85F
- consider a hide, forest litter and plantings for enrichment
