Do fish have painful nerves, and why don t they scream when they are killed?

Fish have painful nerves and scream when they are killed, but the frequency of their voices is not the same frequency as ours, and we can't hear them, so it seems that they don't scream when they are killed.

Fish cannot make sounds without vocal cords, and the nervous system in fish is not very developed, and they cannot transmit pain information to the brain.

Yes, the fish also scream, but we can't hear it, because when we kill the fish, the fish are also jumping around.

Animals of the same species, as long as they have a common language with each other. When fish are killed, humans can't hear their screams, but when they are hurt, they jump and jump. Based on this, it can be judged that fish, like humans, have pain nerves.

The swim bladder is the auxiliary respiratory organ of the fish, when the water surface is separated, when there is no oxygen, only the oxygen in the swim bladder can survive for a period of time, which is the fish after being caught alive, under the palm of the human hand, can also jump around. In addition, it is also the organ of speech, and the fish stop communicating by pressing the air of the swim bladder and making sounds. The amount of air discharged will affect the change of sound transmitted through the medium of water.

The fish will directly inform each other of its mood with its eyes. When absorbed by an object, it will focus first, and then the eyes will roll. About hostile powers, the eyes will widen.

Fish also stretch their fins, abdomen and back, make sounds through hard spines rubbing, rub teeth against each other, and let fish spit out their mouths to inform each other. So much so that they will blow bubbles on the water, jump, and chase. Fish are similar to other animals in the animal kingdom, and there are several species of animals that are mute and can't bark.

Ants, ladybugs, vegetable insects, cockroaches, geckos, etc., do not bark, but there are pain nerves. The pain nerve surface is now sceiving, ** is hurt, you will feel pain, and after the pain, you can't make a sound, you can only struggle. Often these lower animals are considered mute, as long as they are perceived, and no vocal cords are expressed.

Medium animals, on the other hand, have full vocal cords, but humans can't tell what they're called.

Fish are dumb, to put it mildly. But without pain, it's impossible. If there is a heart-rending cry when you are killed, it will scare a lot of people.

If you are hurt, you can only blame the fish for not having the vocal cords that are thriving like humans to express the words you want to express. Generally speaking, animals are hurt, if they can be sentient, they will break free from the intruder or object that hurts them, and animals with normal sentience cannot scream when they are hurt, they cannot say that they have no nerves, and if they do not hurt, how can they struggle.

Fish don't have pain nerves, they don't feel pain, and they don't have enough oxygen to make sounds when they're killed.

The fish will also scream when he is killed, but we can't hear the frequency of the sound he makes, and it also has painful nerves.

There is no corresponding part of the brain where pain is felt, and there is no organ for vocalization.
