Jumping Spiders jump. They use their 'silk' not in a web, but they harness it around a twig or something similar. When they spot their prey, they lunge forward and wrap the food up to eat. If the spider misses, then the string acts as a little safety cord so the spider doesn't fall down to its death. The jumping spider just pulls itself back up and tries again.
most of them due especially when you scare them half to death
I don't think so. Only jumping spiders. Others probably just lounge or pounce on their prey.
i think that they cant because they are to heavy, but they might be able to because there a spider you know?
no they don't they don't have teeth
Jumping spiders are a family of spiders that jump (the salticidae family of spiders). 13% of spider species are jumping spiders. For more information get a book on them, visit http://salticidae.org, or check out the informative wikipedia article on jumping spiders.
they jump so hog high because they need to be able to catch their prey
That is sort of a trick question. Spiders do not engage in athletic contests, so they have no idea of trying to jump just to see how far they can go. Jumping spiders jump as far as they need to in order to reach their prey. They have rarely been observed to fail to catch prey because they jump but fail to reach that far. So they clearly have a good sense of their own limitations. They are likely to creep as near to their prey as they can get without being noticed. So there is probably a reserve margin of jumping capability that jumping spiders rarely use. Just as sumo wrestlers are rarely broad jump champions, heavy-bodied jumping spiders do not jump for as many times their own body length as do light-bodied jumping spiders. A recent study of one small spider showed that it could jump 15 times its body length. The Zebra spider is about the same size, so it probably could jump around 3 inches too.
Jumping spiders can jump horizontally about 25 times their body length. The average jumping spider is about 10mm or less, so that's really not that far (about one foot). That distance is only achieved when they are fleeing something, though. Most regular, non-pressured jumps are just a few centimeters in distance. (source: Biology of Spiders by Rainer Foelix)I'm not sure how high they can jump, though. Can't be that high...
The scientific name for the black jumping spider is Phidippus audax.
I really dont think that jumping spiders can kill any one
Although black widow spiders are not considered "jumping spiders" as popular myths might have you believe, and cannot jump at you, they still should be encountered with great caution as they do have very venemous bites.
Spiders are carnivorous, they eat insects
