Theraphosa stirmi (Burgundy Goliath)

The Burgundy Goliath Bird Eater is a true titan of the arachnid world. Hailing from the humid rainforests of Guyana and Brazil, it is one of the three “true goliaths.” While it lacks the leg-fringe of the T. blondi, it makes up for it with a massive, heavy-set frame and a beautiful deep wine-red or “burgundy” coloration after a fresh molt.

Key Highlights

• Massive Scale: This is one of the largest spiders on the planet by mass. Adults can reach a staggering leg span of 25–28 cm (10–11 inches) and can weigh as much as a young kitten.

• The “Burgundy” Aesthetic: Juveniles and freshly molted adults display a rich, dark reddish-brown hue. As they age through the molt cycle, they fade into a more matte cocoa brown.

• Audible Presence: Like other Theraphosa species, they can produce a distinct “hissing” sound (stridulation) when threatened by rubbing their legs together. At their size, this sound is clearly audible to humans.

• Terrestrial Heavyweight: They are ground-dwellers that prefer to stay low. Due to their immense weight, a fall from even a few inches can be fatal, so their enclosures prioritize floor space over height.
