#27 Goliath Birdeater
The largest spider in the world is the Goliath Birdeater, a tarantula species found in the forests of South America. Contrary to its name, these arachnids don’t regularly include birds in their diet even if they are capable of doing so.
Its bite can scar and feels similar to a wasp sting but, first, it defends itself. It rubs its body and creates a cloud of urticating hairs that irritate the skin, eyes, and respiratory tract, which can trigger an allergic reaction.
