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. See {Spin}.]
   1. (Zool.) 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}.
      [1913 Webster]

   Note: Spiders are divided into two principal groups: the
         Dipneumona, having two lungs: and the Tetrapneumona,
         having four lungs. See {Mygale}. The former group

         {Saltigradae}), the wolf spiders, or {Citigradae} (see
         under {Wolf}), the crab spiders, or {Laterigradae} (see
