FISHES

A fish is any aquatic vertebrate animal that is covered with scales, and equipped with two sets of paired fins and several unpaired fins. Most fish are "cold-blooded," or ectothermic, allowing their body temperatures to vary as ambient temperatures change. Fish are abundant in most bodies of water.

Ten Facts about Fishes

  1. Fish is a poikilothermic cold-blooded water-dwelling vertebrate with gills.
  2. There are over 28,000 fish species in the world.
  3. Fishes can be found in almost all large bodies of water in either salt, brackish and fresh water, at depths ranging from just below the surface to several thousand meters.
  4. Certain species of fishes maintain elevated body temperatures and may be considered endothermic to varying degrees.
  5. Fish range in size from the huge 16-metre (52 ft) whale shark to the tiny 8-millimetre (0.3 in) stout infantfish.
  6. Fish have a closed-loop circulatory system. The heart pumps the blood in a single loop throughout the body.
  7. Fish can be found in nearly all aquatic environments, from high mountain streams to the abyssal and even hadal depths of the deepest oceans.
  8. Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills.
  9. As with many aquatic animals, most fish release their nitrogenous wastes as ammonia. Some of the wastes diffuse through the gills.
  10. Fishes are perhaps one of the hardest subjects to photograph.
