Lampreys live in the water, they will attach to the body of certain fish, and slowly eat the flesh of these fish, this is their unique way of hunting. Generally speaking, the main food of lampreys is fish, and they are not interested in human beings. Therefore, they generally do not take the initiative to bite, but like to find some fish, and take the opportunity to bite them, adsorb on their bodies. However, if they feel threatened by humans, they will bite. Because their teeth are very sharp, people will have more obvious pain after being bitten.

They will seize the opportunity to bite a fish, and then use their sharp teeth to bite through the skin of the fish, and suck out the blood inside. Because they have this characteristic, so some people give them a nickname called "vampire fish", more image. But they don't usually bite. If they are threatened by humans and bite, they may also suck human blood, but this is not common.
