Is a spider web a network?
Thus, a mobile social network application called Spiderweb is implemented and used as a test case. Spiderweb provides to the users an opportunity to make acquaintances, search for people on the basis of certain criteria, chat, view profiles of other users, and with numerous other possibilities.
How does a spider use its Web?
So why do spiders spin webs? The main reason spiders spin webs is to catch their dinner. When an insect, such as a fly, flies into a spider’s web, it gets stuck on the sticky threads. When a spider catches prey in the sticky strands of its web, it approaches the trapped insect and uses its fangs to inject venom.

What spiders use the tube web?
Three are known popularly as funnel-web spiders: Agelenidae, Dipluridae and Hexathelidae.
What is the spider web analogy?
The spider’s web metaphor can represent the web as a result of a constructivist learning process. The knowledge structures from the different radius threads, framed by previous experiences, come together and intersect as the spider spins the spiral threads. This enables sharing of knowledge to a wider audience.
How strong is a spiders web?
Tensile strength is measured in force per unit area, or GPa. The tensile strength of steel ranges from 0.2 GPa to 2 GPa, while the tensile strength of some spider silks is about 1 GPa. Because spider silk is so much smaller than steel, it’s hard to fully understand the comparison in terms of strength.
How effective are spider webs?
New research suggests that the webs may be effective at their primary jobs — catching prey for the creatures that wove them — not only because of their stickiness, and not only because of their strength, and not only because of their unique shape but also because of their responsiveness to electricity itself.

How does a spider make its web?
Spiders are able to spin webs because they can produce silk from structures called spinnerets, which are glands at the base of their abdomens. A spider constructs its web as its spinnerets produce silk, and the kind of web it builds depends on its species.
How do spiders make webs?
Courtship. A male spider displays several behaviors during courtship,hoping the female will accept his sperm.
What are types of spider webs?
Different types of spider webs include: Spiral Orb Webs – Spiral orb webs are the most common spider web. This web design is associated with the family Araneidae and species include orange garden orb weaving spiders, banded orb weaving spiders, bolas spiders and silk spiders, just to name a few.
Where do spiders shoot webs from?
The spiders spin initial connecting threads that are up to 82 feet (25 m) long to suspend these webs from vegetation on either side of a river or other body of water. The arachnids do this even though females are a mere inch (20 millimeters) long and males only a quarter-inch (6 mm) in length.
