List of New World Tarantula Species

30 New World Tarantulas

The New World Tarantulas, which are mostly found in the Americas, have bites that are normally not dangerous to humans (other than causing localized pain). Urticating hairs, which can induce itching and other common human symptoms, are the spiders’ principal means of defense. Some tarantulas and lepidopteran caterpillars use urticating hairs as one of their principal defense systems.

Urticating hairs are barbed hairs that cover the Tarantula’s dorsal and posterior abdomen. Many Tarantula species will kick urticating hairs off their abdomens, aiming them towards possible assailants. These hairs can become embedded in the skin or eyes of other animals, causing physical irritation.

Tarantulas do not have urticating hairs at birth. They form with each successive molt, growing around black hair regions on the upper back and part of the abdomen of juveniles, and widening from molt to molt. The urticating hairs of older Tarantulas blend with the main tone of their abdomen coloration.

The New World When threatened, tarantulas will turn towards the threat and briskly rub their hind legs against the opisthosoma (the posterior part of the spider’s body), firing urticating hairs in the direction of the threat.

New World Tarantulas Characteristic

The size of New World Tarantula species ranges from various small species with leg spans of 7.5 centimeters (3 inches) to others with leg spans of 17.5 centimeters (7 inches) or significantly bigger, such as the Goliath Birdeater tarantula (12 inches).

Most are brightly colored or patterned, and many have beautiful metallic colors of bronze, pink, green, blue, purple, or gold on their carapace, trochanters, and femurs. The majority of New World Tarantulas have both short and long setae (stiff hair, bristle, or bristle-like process or part of an organism). Some species have densely packed setae that are short and silky.

The setae that cover the legs of several species give some Tarantulas a sculpted, streamlined appearance in compared to others, which are often more robust and ‘shaggy’ in appearance. Some species’ males are more densely covered with longer setae than females.

Tarantula spiders from the New World can be found in tropical and desert areas all over the world. Unless they live in a tunnel, new world tarantula spiders do not spin webs. To catch wandering prey, these spiders fill their tunnel with web.



Tarantula spiders from the New World primarily consume insects and other arthropods captured by surprise or ambush. Tarantulas can kill animals as large as lizards, mice, and birds. The tarantula’s mouth is positioned on the lower front section of its prosoma, beneath its chelicerae. The mouth is a short straw-shaped hole that can only suck, therefore anything put into it must be liquid.

Prey containing a large amount of solid parts, such as mice, must be crushed and ground up or predigested, which is done by spraying the prey with digestive secretions ejected from chelicerae apertures.
