Sea fish: list, names, varieties

According to Darwin’s theory, life on Earth originated in the depths of the water, and then appeared on land. That fish is considered to be the ancestors of all the inhabitants of our planet. Now people have learned to use the water wealth, studied the features of the appearance, structure and lifestyle of marine fish.

The diversity of the inhabitants of the water depths is amazing: some are difficult to see with the naked eye, and the biggest fish, the whale shark, reaches 20 m in length.

Studies have allowed to record more than 32,000 species of marine fish.

It is impossible to name a specific number of species of aquatic vertebrates. Studies have recorded more than 32,000 species.

Every year, this list becomes larger, replenished with hundreds of new species of marine fish.

The classification used by modern scientists is as follows:

Many of them are edible and have great commercial value. A large number of aquatic inhabitants prefer to stay away from the coast, and the farther they go into the sea, the more species can be found.

In shallow water, as a rule, small fry are found, and among the stones, larger fishes also find shelter.

Sea inhabitants can be divided into cold-loving and heat-loving, each group is attracted by the appropriate type of flow. So, once in cold streams, a thermophilic fish most often dies.

The habitat of sturgeon fish is often salty sea water, but they spawn in freshwaters. Representatives of this group of fish are very diverse, differ in size from each other.

Thus, the weight can vary from 0.5 to 5 kg, the largest in the list of sturgeon is considered to be a beluga, which can be up to 10 meters in length, and several tons in weight.

Sturgeon is a fairly large resident of the sea waters. Its length reaches 6 meters.

It is found, as a rule, in the Arctic and Atlantic oceans, as well as in the White and Baltic seas. Sometimes this fish is called Atlantic, or lake salmon.

Young individuals use plankton and insect larvae as food; adults who migrate to the sea are predators, preying on capelin, smelt and herring.

Pink salmon has a length of 60 cm and weighs at least 2 kg. The originality of the fish – the presence of a peculiar hump in the males, which gave the name. In females, the spinal growth is not observed.

It is found in reservoirs with cold water. Warm currents and heat adversely affect it, making it passive and lethargic.

Flatfish representatives prefer a bottom lifestyle, characterized by an oblate oval or diamond-shaped body. In the salty waters of the sea, there are dozens of such fish, some prefer depth, and others are found in shallow water.

Representatives of flatfish prefer a bottom lifestyle, are distinguished by a flattened oval or diamond-shaped body.

White-bellied flounder reaches a length of 0.5 m, has a pronounced lateral line of the body, is divided into the northern and southern species. Far Eastern flounder has a commercial value, the lion’s share of world catch falls on this species.

The original fish, the representative of the kalkanovs, is a large rhombus, so named because of its specific body shape. In addition, you can find the name “sea pheasant”. This flounder has no scales, but its entire body is tightly studded with spikes.
