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.
fish have fins. Fins help fish swim forward, turn, and stop, as well as
keep upright. Fins come in various shapes and
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.
