Which Spiders Don’t Spin Webs?
WouterA spider uses silk to weave a web. The web is a strong, sticky structure that can catch prey. It also enables the spider to hide from predators.
A variety of spiders spin webs. Some of the most common types are black house spiders and redback spiders. These spiders create dense webs under eaves and in the voids of roofs. Some webs are simple and easily identified, while others can be confusing and are built to ensnare flying insects.
Crab spiders use silk to wrap egg cases and other items. They also hunt for food. However, some species do not depend on their webs to survive. They wait for prey to come to them.
Peacock spiders are jumping spiders that are found in Southeast Australia. They are very active hunters and take down prey three to four times their size. These spiders do not pose any health risks.
Orb-weavers are another group of spiders that create complex webs. Their webs consist of dragline threads that radiate out from the center. Their claws provide traction as they move. Often, their eyesight is poor, so they use their sense of touch to weave.
In addition to webs, spiders use silk to climb plants. They also produce silk by extruding proteins through the spinnerets. The silk is flexible and five times stronger than steel. Most spiders recycle their silk material into new webs.
Most spiders have eight eyes, but some only have one. Most have a brain that is smaller than a poppy seed. All spiders have two claws on their feet.
