Spider

Spiders are Air-breathing arthropods with eight wings, chelicerae with fangs usually capable of injecting venom, and spinnerets that extrude silk. They are the largest arachnid order and rank seventh among all orders of organisms in total species diversity. Spiders are present on every continent worldwide, except Antarctica, and, with the exception of air and sea colonization, have become known in almost every habitat. The body of a spider consists of a cephalothorax with eyes, mouthparts, a pair of jaws and a pair of pedipalps, and four pairs of jointed legs; and an abdomen with a short pedicel attached to the cephalothorax. A tough protective exoskeleton encloses the whole body and most of the body has sensory hair emerging from the skin.


General Features

Size Range: 

  • Spiders vary from 0.5 to around 90 mm in body length. The hairy mygalomorphs, also referred to as tarantulas, which are found in warm climates and are most abundant in the Americas, are the largest spiders. 

  • The goliath bird-eating spider (Theraphosa leblondi or T. blondi), found in parts of the Amazon, and the pink foot goliath are some of the main mygalomorphs (T. apophysis).

Distribution: 

  • Spiders are found on all continents (except Antarctica, although fragments of spiders have been recorded there) and in the Himalayas at altitudes as high as 5,000 meters (16,400 feet). 

  • In the tropics, several more species exist than in temperate areas. One Eurasian species, while most spiders are terrestrial, is aquatic and lives in slow-moving freshwater. 

  • There are a few animals that live in fresh or salt water along the coast or on the surface. Long silk threads that catch the wind and can take the spiders long distances are secreted by small spiders and the young of many larger species. In many families, this action, called ballooning, occurs and expedites distribution. In this way, several species are spread across the globe within the boundaries of the northern jet stream

Habitat:

  • Multiple species exist in a large range of different ecosystems in this group. Woodlands, lakes, grasslands, deserts, rainforests, and more are some of the many types of habitats in which you can find these animals.

  • Some live in trees and shrubs, some live on the ground, some even in underground tunnels. Regions where humans live, such as homes, fields, barns, gardens, attics, basements, foundations, and more, are often used by a wide range of animals.


Importance of Spiders

All Spiders are observed to be predators. They are the most significant predators of insects because of their abundance. Spiders have been used in Israel and rice fields in China to monitor insects in apple orchards. In South American rice fields and in the fields of various North American crops, a large number of spiders have also been found feeding on insects.The use of insecticides that do the least harm to natural predators of insect pests is emphasised by modern pest control strategies. Although many spiders create venom for use in prey capture, few species are toxic to humans. The black widow's venom (genus Latrodectus) acts as a painful nerve toxin.


Interesting Information About the Spider

  • A spider consumes around 2,000 insects per year, so it is safe to have spiders around the place.

  • Spiders kill spiders. Females consume their partners occasionally, even when they are mating. Some spiders specialize in tracking down other spider species and have developed ways of catching them, even though their victims are at the middle of their webs, their strongholds.

  • Giant Huntsman: This species is the largest in the world in size. Their leg span, or diameter might measure up to a foot across. This species hits speeds of up to 3 ft. per second to make matters more frightening. Their venom does not pose a threat to humans.

  • Patu Digua- This teeny-tiny species is just 0.37 mm or 0.015 inches long. That means about five of these creatures could fit on a pin's head comfortably.

FAQ (Frequently Asked Questions)

1. How Spiders Feed and Hunt?

Ans. Most animals are carnivorous, either trapping or hunting down flies and other insects in their nets. Though spiders inject their prey with digestive fluids, they can't swallow their food as is, then suck out the liquefied remains. Though not all spiders create webs, silk is created by every species. For several different purposes, they use the sturdy, flexible protein fiber: to climb (think Spider-Man), to tether themselves in the event of a fall for protection, to build egg sacs, to wrap up prey, to make nests, and more. 

There are eight eyes in most spider species, but some have six. However, in spite of all those eyes, many don't see very well. The jumping spider, which can see more colors than humans can, is a notable exception. The day-hunting jumping spider can see in the red spectrum, green spectrum, and in UV light, using filters that sit in front of the cells in their eyes.

2. Do Spiders Bite?

Ans. Yes, spiders do bite. On the head end of the cephalothorax, spiders have two small jaws (chelicerae) which end in fangs below the eyes. In glands behind the jaws, venom (poison) is produced and empties along ducts in the fangs to paralyze or kill prey. Since they are unable to pierce the skin with their fangs, very few spiders bite humans. Spider bites can, or you may not feel them at all, cause redness, pain, and swelling. Black widow spider bites can also cause extreme pain or cramping in the abdomen. Brown recluse spider bites can, like a bee sting, cause a sting or sharp pain. With serious bites, within a few hours, the underlying skin can die. Generally, all kinds of spiders live in undisturbed locations, such as attics or sheds.
