A Tarantulas hairy covering actually has two separate functions. The first function of the hairs is to sense air movement around the spider, this allows the tarantula to both detect prey as well as warn the spider of potential enemies! The hairs are called urticating hairs, sounds a lot like irritating, and for good reason. Researchers have determined that there are actually four different types of urticating hairs on the body of some tarantuals.
The hairs will break off the abdomen and irritate the skin of other animals, including humans. Tarantulas can actually use their back legs to flick the hairs off their bodies and onto potential enemies!Each Tarantula leg is made up of seven parts with two claws at the end and a tuft of hair for extra gripping power!
A spider has eight eyes, they are very small and generally not very strong, the spider rarely depends on it’s eyesight. Huge fangs actually help hold the prey item after the Tarantula has grabbed the food item. Each tarantula leg is actually powered by over 30 muscle groups. Much like other small creatures the spider is capable of easily lifting several times its own body weight. Most Tarantulas do not hunt by building webs, they are generally more like a leopard or a cheetah, stalking slowly on the ground the spider will quickly pounce on and hold their food item while their powerful venom goes to work! In fact the tarantula actually uses it eye sight very little to hunt, being almost exclusively nocturnal the tarantula will actually use the darkest of night as the perfect time to go out and find a meal.
