They're big and hairy, but are tarantulas scary? Not when you get to know them! Tarantulas live in warm areas around the world. Some live in underground burows in well-drained soil. If the soil is just right, the spider digs a deep burrow and lines it with silk webbing. Other tarantulas live on the ground under rocks or logs or the shed bark of trees, and still others live in webbed burrows in trees.
