#List of freshwater fish skin

There are different types of fish that develop certain characteristics that allow them to ingest their food completely, many are considered carnivorous fish only for ingesting insects that live in the waters. Yet, the latter is not very common among them and only occurs when they need it. This type of freshwater fish species feeds specifically on smaller fish, but at the same time they can consume any type of species that inhabit the water, such as insects and mollusks. The diet can also vary according to the species that is being treated, since there are diversity of families that feed on various types of food in the water, be they carnivores, herbivores, among other categories. Carnivorous freshwater fish. The freshwater fish’ diet only depends on what is in its habitat and the nutrients that they provide for them and therefore it causes that the feeding habits of the fish are very diverse and can vary according to the case.

Their skin like other vertebrates contains special characteristics, since most freshwater fish are covered by scales which are what allow them to resist the different temperature changes to which they are continuously exposed.Īlthough not all species have scales on their bodies some freshwater fish species contain another type of structure very similar to scales that performs the same function. The tail represents another extra complement to its anatomy, since in the company of the dorsal fins in the trunk area are the ones that provide all the movement to freshwater fish, allowing them to reach the necessary speed to move along and width of the waters where they coexist. It’s worth mentioning that their trunk or abdomen houses most of their organs where a pair of fins can also be seen which give them greatest possible mobility in the water. Their head contains branchial areas which allow them to store the greatest amount of oxygen and to be able to breathe properly in the water. They have the same body aspect as most vertebrates, their characteristics may vary depending on the species to which they belong, their body is made up of a head, trunk or abdominal area and a tail. Since not all waters are the same, some are denser than others with which each type of fish adapts little by little.

In the case of the freshwater fish, their anatomy depends on the water where they are developing. Today there are smaller and more varied species depending on the families to which they belong. Since these beginnings little by little the structure of such fish changed, and different investigations and studies have shown that their anatomy has been altered over the years. Their evolution is a subject that is still under discussion by many experts, since an exact time is not yet known in which it demonstrates the beginnings of the freshwater fish. In their anatomy you can also see some scales throughout their body that allows them to have better mobility. They have special gills that help them regulate their temperature in the water, their body is usually covered by scales that regulate low temperatures. This type of habitat is somewhat small but spacious enough for them to survive comfortably. As we have previously mentioned, freshwater fish are living beings that develop mainly in rivers, lakes, and lagoons.
