Spiders, facts and information

David Cronenberg received the screenplay from Patrick McGrath out of the blue, with a note attached saying that Ralph Fiennes was interested in playing the part of Spider. After about four pages, Cronenberg had decided that he wanted to do the film. The show’s star is a dead spider brought back to life using puffs of air to control its legs. Even if a card is blocked, you can still continue to sequence below the blocked card.

There is strong evidence that spiders' coloration is camouflage that helps them to evade their major predators, birds and parasitic wasps, both of which have good color vision. Many spider species are colored so as to merge with their most common backgrounds, and some have disruptive coloration, stripes and blotches that break up their outlines. In a few species, such as the Hawaiian happy-face spider, Theridion grallator, several coloration schemes are present in a ratio that appears to remain constant, and this may make it more difficult for predators to recognize the species. Most spiders are insufficiently dangerous or unpleasant-tasting for warning coloration to offer much benefit.

Spiders range in size from the tiny Samoan moss spider, which is .011 inch long, to the massive Goliath birdeater, a tarantula with a leg span of almost a foot. In a story told by the Roman poet Ovid in his Metamorphoses, Arachne (Ancient Greek for "spider") was a Lydian girl who challenged the goddess Athena to a weaving contest. Arachne won, but Athena destroyed her tapestry out of jealousy, causing Arachne to hang herself.

As with other arthropods, spiders' cuticles would block out information about the outside world, except that they are penetrated by many sensors or connections from sensors to the nervous system. In fact, spiders and other arthropods have modified their cuticles into elaborate arrays of sensors. Various touch sensors, mostly bristles called setae, respond to different levels of force, from strong contact to very weak air currents. Chemical sensors provide equivalents of taste and smell, often by means of setae.

Those include the black widow and the brown recluse, both found in the United States. There are spiders with a reduced number of eyes, the most common having six eyes with a pair of eyes absent on the anterior median line. Other species have four eyes and members of the Caponiidae family can have as few as two. Cave dwelling species have no eyes, or possess vestigial eyes incapable of sight.

In web-building spiders, all these mechanical and chemical sensors are more important than the eyes, while the eyes are most important to spiders that hunt actively. To avoid being eaten by the females, which are typically much larger, male spiders identify themselves to potential mates by a variety of complex courtship rituals. Males of most species survive a few matings, limited mainly by 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 by carrying them around or by sharing food with them.

You will really need to use your concentration to beat this puzzle game. As a variation to the original Solitaire, Spider Solitaire is a single player card game, with multiple variations, having grown very popular after its inclusion in Microsoft Windows. Throughout the game, if a column or pile is empty, you can move new cards to that pile, which can then be sequenced. You can move a bunch of cards in a row as a single unit to another pile if they are all in descending order of the same suit.

In an act of mercy, Athena brought Arachne back to life as the first spider. Stories about the trickster-spider Anansi are prominent in the folktales of West Africa and the Caribbean. Portia uses both webs and cunning, versatile tactics to overcome prey.

In genera such as Tetragnatha, Leucauge, Argyrodes or Theridiosoma, guanine creates their silvery appearance. While guanine is originally an end-product of protein metabolism, its excretion can be blocked in spiders, leading to an increase in its storage. Structural colors occur in some species, which are the result of the diffraction, scattering or interference of light, for example by modified setae or scales. The white prosoma of Argiope results from bristles reflecting the light, Lycosa and Josa both have areas of modified cuticle that act as light reflectors. The peacock spiders of Australia are notable for their bright structural colours in the males. Spiders reproduce sexually and fertilization is internal but indirect, in other words the sperm is not inserted into the female's body by the male's genitals but by an intermediate stage.
