The radiating, gill-shaped plates forming the under surface of a mushroom. 3. (Zo["o]l.) The fleshy flap that hangs below the beak of a fowl; a wattle. 4. The flesh under or about the chin. --Swift. 5. (Spinning) One of the combs of closely ranged steel pins which divide the ribbons of flax fiber or wool into fewer parallel filaments.

Gill net, a flat net so suspended in the water that its meshes allow the heads of fish to pass, but catch in the gills when they seek to extricate themselves. Gill opening, or Gill slit (Anat.), an opening behind and below the head of most fishes, and some amphibians, by which the water from the gills is discharged. In most fishes there is a single opening on each side, but in the sharks and rays there are five, or more, on each side.
