what does a spider weave and has no eyes and yet can see????

Answer 1

A web

Answer 2

This question is in the wrong category. It should have been under Zoology.One of my favorite subjects.

A spider weave web, cobweb, from proteinaceous spider silk extruded from its spinnerets. Not all spiders build webs to catch prey. Some do not build webs at all.just like the jumping spiders(Family Salicidae). Many spiders are classified by their web they build and the placement of their eyes.

Spiders have very interesting eyes. Most spiders have 8 eyes which vary in size and placement depending on species. So, knowing something about spider eyes can actually help when you’re learning to ID spiders.


Jumping Spider (Family Salticidae).this spider has a very large pair of eyes at the center front. Eyes located at the center front are called “anterior median eyes”. When you see a big set of eyes like that, it usually means that you’re looking at a spider that is a hunter — like the jumping spiders — that must have very good eyesight so that they can locate and capture prey. By the way, this spider does have eight eyes — but four of them aren’t too visible. If you look hard, you’ll see the rear-most pair of eyes back on the side of the head region. Those are called “posterior lateral” eyes. There is actually another pair of eyes in between . They are called the posterior median eyes.



The next spider has a completely different eye arrangement. This spider is a Misumena vatia - often called a Flower Crab Spider. It belongs to the Crab Spider Family (Thomisidae). These spiders don’t move around a lot. Instead, they find a suitable location and then let their prey come to them. They often sit in the center of an attractive flower, looking upwards, legs raised skyward, waiting for an unwary bee, hover fly, or other victim to come looking for pollen or nectar. These spiders sit motionless for hours as they wait for their prey. This spider’s eyes are all contained within a very small area facing front and center. No doubt, they suit this spider’s hunting style, which is to concentrate full attention on an object which comes directly into the spider’s grasp. I might add that, despite this fairly sedentary hunting technique, these spiders seem to be incredibly successful — which probably says something for patience and perseverance.



The next spider is some species of Orbweaver (Family Araneidae). I think it’s probably a Marbled Orbweaver (Araneus marmoreus), but I always find the various species of Araneus a bit difficult to sort out. In any case, this spider spins a large, circular web which can be 20 inches or more in diameter. It then sits in a safe spot, either on the web or nearby. Usually fifound sheltered under the bent tip of a Timothy grass seedhead, just to top and side of their orb. They are said to have poor eyesight — which isn’t too surprising considering the minute size of their eyes. These spiders depend on feeling vibrations from struggling insects in their webs rather than on seeing their prey. When they feel vibrations and tugging on strands of their webs, they crawl to that spot to kill and wrap their prey.



I’ve included these last two spiders as examples of hunting spiders with interesting eye arrangements. I’m quite sure that the above spider is a Dark Fishing Spider (Dolomedes tenebrosus), and is a member of the Nursery Web Spiders (Family Pisauridae). As North American spiders go, this is one of the larger species. As can be seen, the 4 anterior eyes are fairly small and lined up in a row at the front. The center rear pair (posterior median) of eyes are quite large, with a small pair of rear side (posterior lateral) eyes a little off to the sides. This spider hunts in or near water and has good vision which makes it able to capture prey such as large insects, and aquatic creatures such as tadpoles and small minnows.



The last spider of the group is the handsome unidentified Wolf Spider . Although it’s difficult to see all of the eyes, this Wolf Spiders ((Family Lycosidae) have a pair of fairly good-sized posterior median eyes (center rear eyes), and also a somewhat conspicuous pair of lateral posterior eyes (the rear set on the sides of the cephalothorax). Both Pisauridae and Lycosidae spiders have a reflective layer of cells at the back of the eye; giving them good night vision.

The reason why crab spiders are so good at catching bees - they can tell which flowers bees prefer from their smell so lie in wait.

Answer 3

It weaves like a net to catch food and live on.they have tiny eyes on the front of their body.

Answer 4

Answer to this is the only thing if one reads & understands the question right, it NEVER drinks, meaning never intakes water or liquid of any sort, so answer being FIRE, watch movie Nemesis Game, it's all about riddles

Answer 5

Answer 6

because it feels around, like blind people.
