Types of Spiders

The spiders are arthropods having eight legs and come under the class Arachnida. They are classified into many different types and there are around 40,000 species categorized in 109 families. Unlike other insect species, spiders do not possess antennae. Their limbs do not have extensor muscles. The extension of limbs takes place by means of hydraulic pressure. Spinnerets are the glands present at the abdominal tips of spiders. These glands help spiders in spinning silk. Read more on:

Types of House Spiders
Out of the 2,500 spider species found in North America, only few of them are house dwellers. The information about common types of spiders found in house is presented below.

• Common House Spider: The spider is generally found on ceilings in the house. The common house spider bites on rare occasions however, it is not poisonous. Even if these creatures bite, complications like blisters, lesions, etc. do not occur.
• Brown Recluse: The brown recluse spider is a nocturnal creature and hides into bags, boxes, folds of blankets, clothing, etc. The bites of these spiders inject toxic venom in the body. One should therefore, consult a doctor immediately.
• Jumping Spider: These spiders usually enter the house in the cold season. Instead of waiting for its prey to get trapped in the web, these spiders pounce/jump on it. The specialty of these spiders is that among all spiders, their eyesight is the best.
• Long-legged Cellar Spider: The long-legged cellar spider is generally found hanging from webs in corners. The spider's way of defending itself is to vibrate the body rapidly. These spiders are not poisonous and their frequency of biting is very low.
• Sac Spider: The sac spiders do not weave webs and search for spaces to hide. Their bite is painful however, it is not as harmful as that of the brown recluse. Antibiotics need to be used to cure the infection resulting from their bites.

The list of types of spiders presented above includes various spider species from the Mygalomorph and Araneomorph sub orders. The characteristics/features of common types of house spiders too are explained in short. Thus, one gets a rough idea of the classification of spiders.
