A tarantula is a type of spider belonging to the family Theraphosidae. These large, hairy spiders are known for their distinctive appearance, with some species having a leg span of up to 30 centimeters (about 12 inches). Tarantulas are primarily found in warm regions, such as rainforests and deserts, and are mostly nocturnal hunters. They typically feed on insects, small vertebrates, and other invertebrates. Despite their intimidating size and appearance, tarantulas are generally not aggressive towards humans and can be kept as pets by enthusiasts. Their fascinating behaviors and adaptations make them a subject of interest in both nature and pet care.
