Theraphosidae is a family of large, often hairy spiders commonly known as tarantulas. The family comprises approximately 900 described species distributed across tropical, subtropical, and arid regions worldwide. Tarantulas are characterized by their substantial size, with some species reaching leg spans up to 30 cm, and their longevity—females of certain species can live 20 to 30 years. They are primarily nocturnal predators that employ diverse hunting strategies including ambush from burrows, active pursuit, and arboreal hunting. The family exhibits considerable ecological diversity, with species occupying terrestrial burrowing, arboreal, and even cave-dwelling niches.
