Acanthoscurria geniculata – Giant White Knee Tarantula

The Acanthoscurria geniculata, commonly known as the Giant White Knee Tarantula, is a striking New World species prized for its bold black body and vivid white leg banding. Native to the rainforests of northern Brazil, this large terrestrial tarantula is a popular choice among enthusiasts seeking an impressive display spider.

Adult Giant White Knee Tarantulas can reach a leg span of up to 8 inches, making them one of the larger species in the hobby. They are known for their hearty appetite, rapid growth, and generally hardy nature in captivity. A secure enclosure with deep substrate, a hide, and moderate humidity helps replicate their natural forest floor habitat.

While often visible and active, Acanthoscurria geniculata can be defensive and may flick urticating hairs when disturbed. This species is typically recommended for keepers with some prior tarantula experience who appreciate a bold, eye-catching spider with strong feeding responses and impressive size.
