A dace has whiskers. They have two pairs of whiskers, the snout whisker and the jaw whisker. Compared with the two, the snout whiskers are longer and thicker, while the jaw whiskers are shorter. The whiskers of dace are very important to them. Although mackerels also have vision, their vision is not as good as that of humans and other advanced mammals, and they need the assistance of other sensory organs, one of which is the beard. Their whiskers can play a key role when they hunt.
1. Do mackerels have whiskers?
Fish are one of the common animals, and the appearance of different fish may be quite different. From the appearance point of view, the presence or absence of whiskers is one of the important differences between fish. Some fish have whiskers and some fish don't. In this respect, the dace is a bearded fish. Specifically, the dace has two pairs of whiskers. These two pairs of whiskers are different and are divided into snout whiskers and jaw whiskers. Relatively speaking, snout whiskers are longer and thicker, while jaw whiskers are shorter. The whiskers of
fish play an important role for them, and so do the whiskers of dace. Although mackerels have vision, their vision is not as good as that of humans and other advanced mammals, so they need other organs to help them live normally. Beard is one of their important sensory organs, which has the function of sensing the surrounding environment. Especially when hunting, their whiskers can play a key role.
Fish scales are also one of the unique structures of fish, but like beards, not all fish have scales, some fish have scales, some fish do not have scales, and the specific number and size of scales are also different. Mackerel is a kind of fish with scales. Scales cover the surface of their bodies and are of medium size. The scales of dace are of great significance to them. There will inevitably be some bacteria and harmful substances in the water, and fish scales can prevent these substances from entering the body of the fish, thus preventing them from getting sick. In addition, fish scales can also reduce the resistance of mackerel in the water to a certain extent.
