Each solitaire variation has different rules and different ways to win. In Spider Solitaire, not all hands are winnable, no matter what you do. There are strategies that can increase the probability of winning, depending on the game. The 1-suit level may be referred to as the easy level, the 2-suit level as the intermediate level and the 4-suit level as the hard level, also called the advanced level. More suits mean more careful thinking when planning out your next move, because a small accident can trap in a card that you needed desperately!

Malphigian tubules ("little tubes") extract these wastes from the blood in the hemocoel and dump them into the cloacal chamber, from which they are expelled through the anus. However, a few primitive Spiders, the suborder Mesothelae and infraorder Mygalomorphae, retain the ancestral arthropod nephridia ("little kidneys"), which use large amounts of water to excrete nitrogenous waste products as ammonia. In spiders, the cephalothorax and abdomen are joined by a small, cylindrical pedicel, which enables the abdomen to move independently when producing silk. The upper surface of the cephalothorax is covered by a single, convex carapace, while the underside is covered by two rather flat plates.

Cooked tarantulas are considered a delicacy in Cambodia, and by the Piaroa Indians of southern Venezuela– provided the highly irritant bristles, the spiders' main defense system, are removed first. Arachnophobia is a specific phobia—it is the abnormal fear of spiders or anything reminiscent of spiders, such as webs or spiderlike shapes. It is one of the most common specific phobias, and some statistics show that 50% of women and 10% of men show symptoms. It may be an exaggerated form of an instinctive response that helped early humans to survive, or a cultural phenomenon that is most common in predominantly European societies.

There’s a spider with a cartoonish butt, spiders that can jump on demand, and cannibal spiders that look like pelicans. The Chaco golden knee tarantula is one of the larger species of tarantula. Spiders have been the focus of stories and mythologies of various cultures for centuries. Uttu, the ancient Sumerian goddess of weaving, was envisioned as a spider spinning her web.

Many of the family Theraphosidae, which includes tarantulas and baboon spiders, have urticating hairs on their abdomens and use their legs to flick them at attackers. These bristles are fine setae with fragile bases and a row of barbs on the tip. The barbs cause intense irritation but there is no evidence that they carry any kind of venom. A few defend themselves against wasps by including networks of very robust threads in their webs, giving the spider time to flee while the wasps are struggling with the obstacles. The golden wheeling spider, Carparachne aureoflava, of the Namibian desert escapes parasitic wasps by flipping onto its side and cartwheeling down sand dunes.
