Wind Spiders
Wind spiders are known for their fantastic speed, which is where they got their name. They can run at speeds of up to 10 miles an hour. There are many myths spread about them by troops that have gone there, or exaggerations of people hearing tales from soldiers. The true cause of these myths is hard to locate. They do not have any venom, nor do they like to chase humans and eat them.
They are actually one of the least aggressive creatures in nature. But because they are so huge, they get a reputation for being extremely vicious and dangerous. If you bother one, they will leave a nasty cut in your arm that will likely get infected. Some people have taken to keeping them as pets, but they are not popular enough to be found at your local pet store. If you want to get some wind spiders for pets, you will have to find an online dealer.
Wind spiders do not like the sun, even though they live in the desert. They prefer to hunt at night and when out in the daylight, they will stand in the shade of anything they can find. Sometimes this includes a persons' shadow and can scare the person because they think the wind spider is chasing them. This is probably the cause of many of the myths that circulate about them.
