Physical Features

Goliath bird-eaters (Theraphosa blondi) possess several remarkable physical features that contribute to their survival and success as apex arachnids:

  1. Size: Goliath bird-eaters are renowned for their colossal dimensions. Adult females can reach a leg span of up to 30 centimeters (12 inches), making them the largest spiders in the world by mass. They can weigh over 170 grams (6 ounces), dwarfing most other spiders.

  2. Hairs: These spiders are covered in dense, bristly hairs, known as setae, which serve multifunctional purposes. These hairs act as a defense mechanism, deterring potential predators. When threatened, Goliath bird-eaters can use their back legs to kick off these irritating hairs, causing discomfort to the predator’s skin and mucous membranes.

  3. Fangs: Goliath bird-eaters possess large, powerful fangs that can extend up to 2.5 centimeters (1 inch) in length. These impressive appendages are essential for capturing and subduing prey. When hunting, the spiders inject venom into their victims, which immobilizes and begins the process of digestion. While their venom is not considered dangerous to humans, their fangs can cause painful bites.


Goliath bird-eaters exhibit fascinating behaviors that enhance their survival and enable them to thrive within their rainforest habitats:

  1. Nocturnal Lifestyle: These spiders are primarily nocturnal, meaning they are most active during the night. By adopting a nocturnal lifestyle, Goliath bird-eaters can avoid the scorching heat of the day and minimize encounters with potential predators. They emerge from their burrows under the cover of darkness to search for food and mates.

  2. Burrowing Expertise: Goliath bird-eaters are skilled burrowers and construct elaborate underground dens as their homes. These burrows serve as their refuge, providing protection from predators and harsh environmental conditions. The spiders’ burrows can extend as deep as 30 centimeters (12 inches) into the ground, with intricate tunnels and chambers.

  3. Ambush Predation: When hunting, Goliath bird-eaters employ an ambush strategy. They lie in wait near the entrance of their burrows, concealed by a camouflaged covering and relying on their sensitive leg hairs to detect vibrations from passing prey. Once an unsuspecting victim approaches, the spider lunges forward with lightning speed, using its fangs to deliver a venomous bite that incapacitates the prey.

By capitalizing on their physical features and exhibiting adaptive behaviors, Goliath bird-eaters have evolved into formidable predators within their rainforest ecosystems. These adaptations allow them to secure sustenance and protect themselves from potential threats.
