Spiders (order Araneae) are air-breathing arthropods that have eight legs‚ and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other groups of organisms.[1] Spiders are found worldwide on every continent except for Antarctica‚ and have become established in nearly every habitat with the exception of air and sea colonization. As of 2008‚ approximately 40‚000 spider species‚ and 109 families have been recorded by

Bromeliad-Living Spiders Improve Host Plant Nutrition and Growth Mutualism has become an important area of research in ecology. Plant performance can be improved if organisms‚ such as ants or spiders‚ reduce the damage to floral tissues caused by phytophages. Most mutualistic relationships that have been studied focus on the influence certain organisms have on improving plant performance and the shelter/ food the plant provides in return. For example‚ the Cecropia tree is defended by colonies

The spider I’m doing my report on is called the Golden Orb spider‚ better known as the banana spider. 0The golden orb spiders are found in dry open places in forests‚ woodlands‚ coastal sand dunes‚ shrubland‚ and mangrove habitats. Some of the golden orb spiders live nearby bushes and flowers. All orb weaving spiders make suspended‚ sticky‚ wheel-shaped orb webs. The webs are placed in the openings between trees and shrubs where insects mostly fly. There are species of banana spider in Africa (including

Project Web Project web is a plan to end all vehicle transportation. This will bring the world to a new age. Spider silk is the key to this project. Its strength is very important. Its stickiness helps catch prey. The production of silk is very important. First‚ strength of silk. Second‚ the stickiness of silk. Last‚ the production of silk. The strength of silk can keep bugs from breaking through. It also prevents them from falling down. The strength of it also prevents snapping randomly. Dragline

The Spider and the Wasp Alexander Petrunkevitch shows great details about nature and its creatures. Like one of his story “The Sider and the Wasp.” Two different creatures trying to live another day‚ jet for some reason they look for conflict with one another. Those two creatures that are the same but different in their own way “is a classic example of what looks like intelligences pitted against instinct” (Petrunkevitch 59). The tarantula and the digger (pepsis) are both

Paragraph 3: 5/5 What are some possible human uses for spider silk? 5/5 How are humans influenced by spider silk when developing products or new inventions? 5/5 Are there other organisms that produce silk besides spiders? If so‚ describe the organisms. A spider’s silk is made up of a chain of amino acids. This means that it is a protein. There are two primary amino acids called glycine and alanine. Spider silk is very strong and is about five times strong than steel and twice as strong as

My favorite page of the Tony DiTerlizzi version of "The Spider and the Fly" was the illustration of the spider and fly at the entrance to the parlor. I liked this picture in particular because I thought that the warning signs for the fly to not go into the parlor were less obvious than other parts of the book‚ even though it was at the climax point of the fly making her decision to accepts the spider’s original offer or not. The subtle images in the picture are the butterfly wing curtains and the

Spider silk What is Spider silk? Spider silk is incredibly tough and it is stronger by weight than steel. Quantitatively‚ spider silk is five times stronger than steel of the same diameter. It has been suggested that a Boeing 747 could be stopped in flight by a single pencil-width strand and spider silk is almost as strong as Kevlar‚ the toughest man-made polymer. It is finer than the human hair and is able to keep its strength below -40°C. Spider silk is also very elastic and capture

do Wolf Spiders Prefer to Live in and What is Their Response to a Change in Environment? Abstract What environment do wolf spiders prefer to live in and what is their response to a change in environment? After performing experiments on wolf spiders it was determined that they prefer to reside in an area covered with leaves over an area devoid of any material. It was also determined that temperature plays a role in how much weight a spider can gain. As temperatures lower spiders on average

The Portia spider trespasses other spiders’ webs‚ disguising itself by plucking at the threads to imitate the vibrations of a mosquito to sneak up on other spiders. Most spiders behave in two certain ways‚ building webs to capture prey or hunting away from their webs. The Portia spider does both. Instead of scurrying and jumping like most‚ these spiders are slow and choppy. Very odd in appearance‚ the difference can be easily seen aside from other species. Portia contain 15 species of African‚ Asian
