Spider Solitaire 2 Suits

In addition to arthropods, some mygalomorphs are known to prey on frogs, small mammals, lizards, snakes, snails, and small birds. Araneomorphae account for the great majority of modern spiders, including those that weave the familiar orb-shaped webs. The Jurassic and Cretaceous periods provide a large number of fossil spiders, including representatives of many modern families.

Many experiments have been conducted to study the effect of zero gravity on the design of spider webs. The smallest, Patu digua from Colombia, are less than 0.37 mm (0.015 in) in body length. The largest and heaviest spiders occur among tarantulas, which can have body lengths up to 90 mm (3.5 in) and leg spans up to 250 mm (9.8 in). The tiny male of the golden orb weaver is protected from the female by producing the right vibrations in the web, and may be too small to be worth eating.

While the current version of Spider oringinates from 1949, the first mention of Spider comes Games Digest published in 1937. They describe the game we know today as Spider, slightly differing in having a 50-card initial tableau instead of 54. However, they talk about it as a well-known game, so it's likely Spider has its orgins from the early 1930's at least. The Foundations are the four piles on which a whole suit or sequence must be built up. In most Solitaire games, the four aces are the bottom card or base of the foundations. They are distinguished by having fangs that oppose each other and cross in a pinching action, in contrast to the Mygalomorphae, which have fangs that are nearly parallel in alignment.

Some pump digestive enzymes from the midgut into the prey and then suck the liquified tissues of the prey into the gut, eventually leaving behind the empty husk of the prey. Spiders have developed several different respiratory anatomies, based on book lungs, a tracheal system, or both. Mygalomorph and Mesothelae spiders have two pairs of book lungs filled with haemolymph, where openings on the ventral surface of the abdomen allow air to enter and diffuse oxygen. The tracheal system has most likely evolved in small ancestors to help resist desiccation. Spiders that have tracheae generally have higher metabolic rates and better water conservation.

A minority of species are social, building communal webs that may house anywhere from a few to 50,000 individuals. Social behavior 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. Other ambush predators do without such aids, including many crab spiders, and a few species that prey on bees, which see ultraviolet, can adjust their ultraviolet reflectance to match the flowers in which they are lurking. Wolf spiders, jumping spiders, fishing spiders and some crab spiders capture prey by chasing it, and rely mainly on vision to locate prey. Spiders have primarily four pairs of eyes on the top-front area of the cephalothorax, arranged in patterns that vary from one family to another.

Many spiders inject venom into their prey to kill it quickly, whereas others first use silk wrappings to immobilize their victims. Spiders often attach highly visible silk bands, called decorations or stabilimenta, to their webs. Field research suggests that webs with more decorative bands captured more prey per hour.

In some cultures, spiders have symbolized patience due to their hunting technique of setting webs and waiting for prey, as well as mischief and malice due to their venomous bites. The Italian tarantella is a dance to rid the young woman of the lustful effects of a spider bite. Web-spinning also caused the association of the spider with creation myths, as they seem to have the ability to produce their own worlds. They placed emphasis on animals and often depicted spiders in their art. The only living members of the primitive Mesothelae are the family Liphistiidae, found only in Southeast Asia, China, and Japan.

The heart is a tube in the upper part of the body, with a few ostia that act as non-return valves allowing blood to enter the heart from the hemocoel but prevent it from leaving before it reaches the front end. The blood of many spiders that have book lungs contains the respiratory pigment hemocyanin to make oxygen transport more efficient. Build a sequence of cards in the piles by moving any face up card on top of a card with the next-highest value, such as a 9 of spades moving onto a 10 of spades. For most people, the thought of spiders conjures up images of tarantulas, wolf spiders, and other fearsome creatures. Though all spiders have venom to one degree or another, only a handful are dangerous to humans.
