Popularly touted as the ‘Giant White Knee’ or the ‘Brazilian White Knee’ tarantula, the Acanthoscurria Geniculata is a breathtakingly beautiful bird spider which is best known for its spectacular coloration and aggressive nature. This creature also grows pretty fast, achieving a leg-span of eight to nine inches in as less than two to three years.

When you spot the White Knee for the first time, you’d be blown away by its elegant chocolate brownish carapace, which is beautifully contradicted with the white stripes along its legs. Unlike many other bird spiders, the White Knee prefers aggressively hunting its prey. In fact, it is this creature’s aggression that makes it so strikingly attractive among experienced tarantula owners.
The Brazilian White Knee can be moody and pretty fast. So, if you’re planning to have them as pets- stay prepared for their quick movements and changing temperaments.
