spiders are the 8est creatures on any planet!!!!!!!! Just take my spider lusus for example.
She may seem a 8it terrifying and 8lood thirsty, which she is. She still cares, She uses her we8s to not only take care of the trolls i bring her 8ut to 8andage up my wounds. She's the 8est example of the perfect spider i know of. Her we8s are amazing. Her thin silk weaves perfect little we8s, each one with a unique design. She cant leave the hive to catch her own prey so i have to find weak usless low-8looded trolls to feed her.
Spiders are air-8reathing arthropods that have 8 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 orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat with the exceptions of air and sea colonization. At least 45,700 spider species have 8een discovered.
Their abdomens 8ear appendages that have 8een modified into spinnerets that extrude silk from up to six types of glands. Spider webs vary widely in size, shape and the amount of sticky thread used. It now appears that the spiral or8 we8 may 8e one of the earliest forms, and spiders that produce tangled co8webs are more abundant and diverse than or8-we8 spiders. Spider-like arachnids with silk-producing spigots appeared in the Devonian period about 386 million years ago, 8ut these animals apparently lacked spinnerets. True spiders have 8een found in Car8oniferous rocks from 318 to 299 million years ago, and are very similar to the most primitive surviving su8order, the Mesothelae. The main groups of modern spiders, Mygalomorphae and Araneomorphae, first appeared in the Triassic period, 8efore 200 million years ago.
A her8ivorous species, 8agheera kiplingi, was descri8ed in 2008, 8ut all other known species are predators, mostly preying on insects and on other spiders, although a few large species also take 8irds and lizards. Spiders use a wide range of strategies to capture prey: trapping it in sticky we8s, lassoing it with sticky 8olas, mimicking the prey to avoid detection, or running it down. Most detect prey mainly 8y sensing vi8rations, 8ut the active hunters have acute vision, and hunters of the genus Portia show signs of intelligence in their choice of tactics and a8ility to develop new ones. Spiders' guts are too narrow to take solids, and they liquefy their food by flooding it with digestive enzymes and grinding it with the 8ases of their pedipalps, as they do not have true jaws.
Male spiders identify themselves by a variety of complex courtship rituals to avoid 8eing eaten 8y the females. Males of most species survive a few m8ings, limited mainly 8y their short life spans. Females weave silk egg-cases, each of which may contain hundreds of eggs. Females of many species care for their young, for example 8y carrying them around or 8y sharing food with them. A minority of species are social, 8uilding communal we8s that may house anywhere from a few to 50,000 individuals. Social 8ehavior ranges from precarious toleration, as in the widow spiders, to co-operative hunting and food-sharing. Although most spiders live for at most two years, tarantulas and other mygalomorph spiders can live up to 25 years in captivity.
