Can fish see in the water?
Humans don’t see very well underwater. But the eyes of the fish have special lenses to see clearly, at least at short distances. In addition, because of the arrangement of their eyes, they have a panoramic view that humans do not have.
Can the fish hear?
They have very dense calcifications in their ears, the so-called auditory stones. Impacting sound waves cause the body of the fish to vibrate, but not the inertial mass of the hearing stone. The fish oscillates with the surrounding water, while the listening stone maintains its position due to its inertia.
How do fish orient themselves in the water?
Fine hair sensory cells in this system perceive the movements of the water. Figuratively speaking, fish lead a bow wave in front of them. If this hits an obstacle, it is thrown back to the sideline organ. This is how fish can determine the size, distance, and shape of an obstacle.
Can a fish cry?

How do fish see the water?

What is the IQ of a fish?
The conclusion of his research is: that fish are significantly smarter than was previously believed, and their intelligence quotient (IQ) corresponds approximately to that of primates, the most highly developed mammals.
Can a fish die of thirst?
The saltwater fish is salty on the inside, but on the outside, it is surrounded by a liquid with an even higher concentration of salt, namely the saltwater sea. Therefore, the fish constantly loses water to the sea. He would die of thirst if he didn’t drink constantly to replenish the lost water.
Is an Aquarium Good for Fish?
