"The World's Biggest Spider: The Goliath Bird-Eating Tarantula" explores the intriguing characteristics and behaviors of the largest living spider found in the rainforests of South America. The Goliath bird-eating tarantula resides in underground burrows and boasts an impressive leg span of up to a foot, weighing just under half a pound. Despite its formidable size and deadly inch-long fangs, its venom is not dangerous to humans. The spider's body is covered in long, dark hairs, which it can project as a defense mechanism. It uses its poor eyesight and sensitive body hairs to detect prey, which includes lizards, frogs, mice, and occasionally small birds. The Goliath tarantula's life cycle comprises regular molting, the ability to regenerate lost legs, and distinct longevity differences between genders. While sometimes kept as exotic pets, their defensive behaviors can make them unsuitable for most people.
