First and foremost, as with many rules in science there are exceptions. Today, however, we will stick to the traits common to most jumping spiders.
Jumping spiders are unique in several ways, but our focus will be on the three biggest differences that set them apart from other spiders. These differences are:
- No webs
- Excellent vision
- Very smart
Unlike most other spiders, jumping spiders do not spin webs for prey capture, but rather hunt them like miniature, eight-legged cats. They do still produce silk, and it is used in hunting, but not for prey capture. Rather, they use the silk as a safety line, similar to a rock climber's rope.
