Spiders are, for the most part, such generalist feeders that they kill many useful insects as well as many pest species, however because pest species are by their nature more numerous than beneficial species they are still effective. They are of great value to the environment.
Spiders (Araneae) are one type of arthropod. They use the Malpighian Tubule System and excrete their wastes through an anus. Some older species of spiders even use small kidneys, but this requires much water.orseshoe crabs (Limulidae) are another example of arthropods. They use a mix of methods to excrete wastes from both terrestrial and aquatic arthropods. They secrete wastes through the gills while at the same time are able to excrete feces through and anus and excrete urine as well by using kidneys.
