Rivers and Streams

Of course fish inhabit rivers and streams, but there are many different species of fish. Such as trout, salmon, many species of sculpins, minnows, bass, catfish, etc. Some of the world's largest rivers are home to some large, ancient fishes, including the paddlefish, gar, sturgeon, and the Yangtze River's gladiator fish. Eels and lamprey are found in many rivers. Some African rivers have fish that can communicate with electrical signals. Even a number of shark and ray species live out their whole lives in freshwater, and others who usually live in the sea will sometimes swim up river mouths. Bull sharks are famous for this and can sometimes be found at some distance up the San Juan, Amazon, and Mississippi Rivers.

Rivers and streams are bodies of flowing water moving in one direction. Streams and rivers can be found everywhere they get their starts at headwaters, which may be springs, snowmelt or even lakes, and then travel all the way to their mouths, usually another water channel or the ocean.
