These colossal arachnids can be found in the South American rainforests, specifically in Brazil, Venezuela, and Suriname. They prefer to reside in deep burrows that they excavate in the soil, where they can avoid predators and hunt small creatures such as insects, lizards, and occasionally birds. The rainforest ecosystem provides them with ample sources of nourishment, allowing them to flourish.


Despite their imposing presence, Goliath bird-eating spiders are generally meek and timid creatures that prefer to evade confrontation. They are known to be solitary beings that only congregate during breeding season. If provoked, they will stand on their hind legs and expose their fangs, but they will only bite as a last resort. While their venom is not fatal to humans, it can cause inflammation and pain that can last for hours.

They are not commonly traded as pets due to their size and aggressive behavior, which aids in safeguarding their natural populations. However, their habitat is endangered by deforestation and other human activities, which could jeopardize their long-term survival.

Its size, appearance, and behavior make it an enthralling subject for investigation and observation.
