5 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Spider \Spi"der\, n.[OE. spi[thorn]re, fr AS spinnan to spin; -- so named from spinning its web; cf D. spin a spider, G. spinne, Sw spindel. Seee {Spin}.] 1. (Zo["o]l.) Any one of numerous species of arachnids comprising the order Araneina. Spiders have the mandibles converted into poison fangs, or falcers. The abdomen is large and not segmented, with two or three pairs of spinnerets near the end by means of which they spin threads of silk to form cocoons, or nests, to protect their eggs and young. Many species spin also complex webs to entrap the insects upon which they prey. The eyes are usually eight in number (rarely six), and are situated on the back of the cephalothorax. See Illust. under {Araneina}. Note: Spiders are divided into two principal groups: the Dipneumona, having two lungs: and the Tetrapneumona, having four lungs. See {Mygale}. The former group includes several tribes; as the jumping spiders (see {Saltigrad[ae]}), the wolf spiders, or {Citigrad[ae]} (see under {Wolf}), the crab spiders, or {Laterigrad[ae]} (see under {Crab}), the garden, or geometric, spiders, or {Orbitell[ae]} (see under {Geometrical}, and {Garden}), and others See {Bird spider}, under {Bird}, {Grass spider}, under {Grass}, {House spider}, under {House}, {Silk spider}, under {Silk}. 2. (Zo["o]l.) Any one of various other arachnids resembling the true spiders, especially certain mites, as the red spider (see under {Red}). 3. An iron pan with a long handle, used as a kitchen utensil in frying food. Originally, it had long legs, and was used over coals on the hearth. 4. A trevet to support pans or pots over a fire. From WordNet r 1.6 [wn]: spider n 1: predatory arachnid that usually has silk-spinning organs at the back end of the body; they spin silk to make cocoons for eggs or traps for prey 2: a skillet made of cast iron From Jargon File (4.2.3, 23 NOV 2000) [jargon]: spider The Web-walking part of a search engine that collects pages for indexing in the search engine's database. Also called a {bot}. The best-known spider is Scooter, the web-walker for the Alta Vista search engine. From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: spider(Or "robot", "crawler") A program that automatically explores the {World-Wide Web} by retrieving a document and recursively retrieving some or all the documents that are referenced in it This is in contrast with a normal {web browser} operated by a human that doesn't automatically follow links other than {inline images} and {URL redirection}. The algorithm used to pick which references to follow strongly depends on the program's purpose. {Index}-building spiders usually retrieve a significant proportion of the references. The other extreme is spiders that try to validate the references in a set of documents; these usually do not retrieve any of the links apart from redirections. The {standard for robot exclusion} is designed to avoid some problems with spiders. Early examples are {Lycos}, {WebCrawler}, and {Yahoo!}. {Home (http://info.webcrawler.com/mak/projects/robots/robots.html)}. (1999-08-26) From Easton's 1897 Bible Dictionary [easton]: Spider The trust of the hypocrite is compared to the spider's web or house (Job 8:14). It is said of the wicked by Isaiah that they "weave the spider's web" (59:5), i.e., their works and designs are like the spider's web, vain and useless. The Hebrew word here used is _'akkabish_, "a swift weaver." In Prov. 30:28 a different Hebrew word semamith is used It is rendered in the Vulgate by stellio, and in the Revised Version by "lizard." It may however, represent the spider, of which there are it is said about seven hundred species in Palestine.
