What's the difference between fluid and spiracle?

Fluid


Definition:

  • (a.) Having particles which easily move and change their relative position without a separation of the mass, and which easily yield to pressure; capable of flowing; liquid or gaseous.
  • (n.) A fluid substance; a body whose particles move easily among themselves.

Spiracle


Definition:

  • (n.) The nostril, or one of the nostrils, of whales, porpoises, and allied animals.
  • (n.) One of the external openings communicating with the air tubes or tracheae of insects, myriapods, and arachnids. They are variable in number, and are usually situated on the sides of the thorax and abdomen, a pair to a segment. These openings are usually elliptical, and capable of being closed. See Illust. under Coleoptera.
  • (n.) A tubular orifice communicating with the gill cavity of certain ganoid and all elasmobranch fishes. It is the modified first gill cleft.
