Why can fish swim?

The physique of the fish is crucial

It is well known that fish have neither arms nor feet and yet they can swim. This is due, among other things, to their physique:

• If you take a closer look at the fish, you will find that all fish have an elongated, narrow body. There are only a few subspecies whose girth is wider than their length.
• Also, notice that the fish have fins and a tail. And depending on the type of fish, they have several fins that are also suitable for different swimming maneuvers.
• You are sure to find interesting the fact that not every fish can do the same thing. There are fish that can rest on the ocean floor, then there are species that can maneuver on the spot (like a parking car) and then there are those who can do a quick sprint, but after a few meters physically am Are over.

That is why these animals can swim

• If you observe fish, you will find that their entire bodies move as they swim. This is called the undulating motion that starts at the head and ends at the tail. This causes the fish to move forward.


Goldfish are losing color - that could be the reason

Don't worry if the goldfish loses color. Mostly it is a harmless ...

• If you also include the fins in your observation, you can see that they are also heavily involved in the swimming movements. But here, too, there are differences: there are rowing and wing-like fins.
• The rowing fins are responsible for steering while swimming. This allows the fish to swim around between the corals; the wing-like fins, on the other hand, provide buoyancy, which is why the animals can also move up and down.
