There is a lot of data that we do not know about marine life. Surely you have also asked yourself certain things about fish, and this article will give you the answers you need!
It is important to note that although this article is focused on saltwater fish, many things that we will explain also apply to freshwater fish.
Also, if you have an aquarium at home, some of this knowledge will help you to better understand your fish.
Do the fish sleep?
This is one of the questions that we have all asked ourselves on occasion and the answer is YES.Although the fish seem to be awake and in continuous movement all day, there are times throughout the day when they “sleep”. Do not go into deep sleep as we enter humans. Moreover, they can not even close their eyes since they do not have eyelids.
However, your metabolism slows down and your movements become slow. Some fish need to keep moving to keep breathing, while others just stand on rocks or corals and stay still until they “wake up”.
What are the largest and smallest fish in the world?
The marine animals listed as the largest fish in the animal kingdom are whale sharks . These can reach up to 12 meters long and, unlike the concept we have of “carnivorous shark”, they feed on phytoplankton, krill, small fish, crustaceans and algae.
On the other hand, the smallest fish in the world is the Philippine goby , which measures only 7.6 millimeters. This fish lives on the coral reefs of the warm waters of the Pacific Ocean and the Red Sea.
Can fish feel pain?
This is a controversial issue, as many experts were not entirely sure until recently. However, recent studies have shown that fish have the same senses as human beings, plus an additional one that provides them with a “radar” with which to detect what is happening around them.
Having the same senses as human beings, it is clear that they CAN feel pain. This means that you can not neglect your fish tank, because if you do not take care of your fish they will not only die, but also they will do it with as much pain as a human being.
Can fish make sounds?
It is often thought that fish are extremely silent animals. However, they can make noises by grinding their teeth or cracking their swim bladders. We simply do not listen to them because these noises are made under water or at frequencies that we do not detect.
In what unusual places can we find fish?
At this point I am not talking about live fish, but about processed parts of them. Many products that we use in our daily life have been manufactured with certain parts of fish and then we use them or consume them without knowing it.
Some examples of these products are lipsticks, which contain fish scales and some lines of clothing, which are made with the shell of the crabs (although they are not considered fish as such).
However, there is a product that you are sure to use very regularly and do not suspect that it contains fish. Toothpaste! – Fish Care Tips
