Something Fishy

There are more than 24,000 species of fish living today. All fish have some things in common:

  • They breathe with gills. As water flows past the gills, oxygen in the water passes through the gill membranes and into the fish's blood.
  • All fish have fins.  Fins help fish swim forward, turn, and stop, as well as keep upright. Fins come in various shapes and sizes.
  • Most fish also have scales and most hatch from eggs. Fish can be found in oceans, rivers and wetlands all over the world, including saltwater and freshwater.
  • They come in an incredible variety of shapes, sizes and colors and have adapted for their watery world with amazing features like puffing up to look much bigger, or making themselves flat as a pancake for a life on the ocean floor, and some even glow in the dark.


Stop by the Wayne M. Densch building to see our saltwater aquariums (250 gallon and 310 gallon).
