The swimming methods of fish are so diverse that you can talk about them for hours. The main parts of the fish body are muscles and fins, it is with their help that fish move in the water.
The world of oceans, seas, rivers and lakes is filled with many inhabitants. Fish belong to most of the inhabitants of the deep water, but even in their huge family there are countless species. Almost all of them have common structural features, thanks to which they swim, more precisely, they move very quickly in their native element.
Muscles and fins of fish: engine, steering wheel and brakes
Muscles constitute the bulk of the fish's body. They connect to the spine and fins, providing mobility through contractions. Thanks to the developed muscles, fish can masterfully control their own body, causing undulating movements of the entire body or tail.
The fins are also connected to muscle fibers and, if necessary, can fold and unfold, changing the direction and speed of movement in the water. The main engine of fish is the tail fin, a perfect oar created by nature, thanks to which marine animals move forward.
Paired pectoral and pelvic fins allow the fish to move up and down, while the dorsal and caudal fins allow them to stay upright and avoid turning around their own axis.
The tail fins also serve as a brake for fish, and with the help of the pelvic fins, they can also rise to the surface. Fins can have a variety of functional features that vary depending on the situation and the species of fish.
In the family of marine inhabitants, there are many exceptions to the general traffic rules. They are due to the variety of animals and their role in the underwater world. It is for this reason that they are so interesting to watch.
Swimming methods in fish
Swimming is a classic for marine species such as sharks, herring, marlin and mackerel. Their bodies move rapidly, moving evenly from side to side. Trout and salmon make quick maneuvers during hunting, long swims upstream, and also fleeing predators.
The tuna makes long sea passages, thanks to slightly noticeable body movements, uses a sickle-shaped tail as a rudder. And eels use only their muscles and a prehensile tail for movement, their fins have practically died out as unnecessary.
The seahorse moves in an interesting way in the water. Its dorsal fin fluctuates with surprising speed. This fin is the only means for making sea trips and searching for food.
Watching the swimming of fish, you can see how diverse and beautiful the underwater world is, with what imagination and prudence it was created by nature and presented to man. Protecting this oasis and studying its features is a big and difficult task for many years to come.
