Do jumping spiders jump?
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.
