Why Do Salmon Jump?

Answer

Scientists have several theories about why salmon jump. One is that jumping out of the water allows the salmon to catch the scent of his native stream--that is, jumping lets the salmon find his way home by smell. They also may jump simply to get over obstacles in the stream. Another theory is that, at least for females, jumping physically prepares the skein of the salmon for spawning. Lastly, some of the jumping may be for plain enjoyment.
