Tarantulas are large hairy spiders that live in warm areas around the world, including South America, southern North America, southern Europe, Africa, southern Asia, and Australia. The greatest concentration of tarantulas is in South America. There are about 300 species of tarantulas. The biggest tarantula is Pseudotherathosa apophysis, which has a leg span of about 13 inches (33 cm). These arachnids have a very long life span; some species can live over 30 years.
Habitat: Some tarantulas live in underground burrows; some live on the ground, and others live in trees. They live in rain forests, deserts, and other habitats. Diet: Tarantulas are carnivores (meat-eaters). They eat insects (like grasshoppers and beetles), other arachnids, small reptiles (like lizards and snakes), amphibians (like frogs), and some even eat small birds. Tarantulas kill their prey using venomous fangs; they also inject a chemical into the prey that dissolves the flesh. Tarantulas can crush their prey using powerful mouthparts. No person has ever died of a tarantula bite.
Anatomy: Tarantulas have a hairy two-part body and very strong jaws (with venomous fangs). They have eight hairy legs; each leg has 2 tiny claws at the end and a cushioning pad behind the claws. The hairs on the body and legs are sensitive to touch, temperature, and smell. Tarantulas have a hard exoskeleton and not an internal skeleton.
