  Water spider \Wa"ter spi"der\ (Zool.)
     (a) An aquatic European spider (Argyoneta aquatica) which
         constructs its web beneath the surface of the water on
         water plants. It lives in a bell-shaped structure of
         silk, open beneath like a diving bell, and filled with
         air which the spider carries down in the form of small
         bubbles attached one at a time to the spinnerets and hind
         feet. Called also diving spider.
     (b) A water mite.
     (c) Any spider that habitually lives on or about the water,
         especially the large American species (Dolomedes   lanceolatus
         ) which runs rapidly on the surface of water;
         -- called also raft spider.
