Hairy Tarantula
Tarantula species are distinguishable from other spiders by the dense body hair. In addition, tarantulas native to North and South America, also known as New World tarantulas, possess urticating hairs, which they use to defend themselves from predators.
The New World tarantula's urticating hairs bear microscopic barbs at the tips. Tarantulas with urticating hair can be identified by a bald spot on the lower abdomen. If a New World tarantula perceives danger, it will flick these needle-like hairs at its attacker. Hundreds of urticating hairs can become airborne at once.
Although they are not venomous, urticating hairs prove to be an effective defense against attackers. When they come into contact with skin or the eyes of an advancing foe, they cause discomfort. Skin rashes, itchiness or allergic reactions may occur in humans. Sensitive persons can experience serious effects that require the assistance of a medical professional.
