Salmon I have no memory of what a salmon looks like, and I probably wouldn't recognize one even if I were asked to. It is this kind of fish that I have only seen on TV and have never seen before in my life, but it is a fish that I have memorized and will never forget. It is like the call of the hometown, always in the deepest part of the heart called people haunting dreams. I feel most y is the salmon's habits. Salmon originally inhabited the northern Pacific Ocean, living in the ocean for three to five years. In order to reproduce their offspring, they must go through a lot of trouble to enter the river and go up to the spawning ground to reproduce. They travel up the river, day and night. Whether they encounter shallow canyons or fast-flowing waterfalls, it never retreats, rushing through numerous obstacles and crossing layers of barriers until it swims to its destination and finds a suitable spawning ground. In order to cross waterfalls or obstacles, salmon use their tails to strike the water with all their might, swimming at high speeds and leaping diagonally out of the water upwards, jumping up to two or three meters into the air. Some salmon can't withstand the impact of the waterfall rapids,
