Whaling mammals types and representatives of the detachment, a list with photos and names

Whaling are the largest in size of all animals living on the globe. They belong to the “mammals” detachment and are adapted to life in water. Water mammals are whales, sea pigs and dolphins.

The streamlined dropshaped shape of the body of whaling allows them to move easily and reduces the resistance of water. Characteristic of a detachment of whaling is heatblood. For breathing, they are adapted lungs, cubs, the female feeds milk. Instead of the front limbs, they have flippers, and in the tail a fin. There is a small hairline on the body of whales.

Features of whaling

In whaling, the sense of smell and taste receptors are completely atrophied. They are able to recognize only salty food. Vision in animals is also bad. Thanks to the many nerve endings, in kitoid, touch is well developed.

The inner ear is arranged so that it allows you to take highfrequency sounds and ultrasounds. Animals communicate due to sounds perceived by an echolocation body located in the area of ​​the skull. Keatoma does not have vocal cords.

Whaleshaped can be under water for a long time without breathing. The offspring are reproduced once every two years.

The evolution of whaling

It is assumed that the ancestors of whaling are articulated animals that gradually migrated to the aquatic environment.

More than 56-60 million years have passed when mesonichia existed on Earth. They had hooves, but outwardly they looked like wolves. Mesonichia lived near the Mediterranean Sea and ate animals living in water and fish. Most of the time animals were in the aquatic environment, and their body took the streamlined shape. They have tails, and the front paws were transformed into fins. The woolen cover disappeared and subcutaneous fat began to increase. For breathing to be carried out above the water surface, the nostrils moved to the top of the head.

Genetic and molecular studies conducted by scientists have shown the presence of kightshaped ties with extinct artricious indochius. They lived on the lands of today’s Pakistan. For 22 million years, the ancestors of whaling gradually moved to sea waters. Thus, an ecological niche was filled, released by extinct mosaurs and pleusiases.

Over time, whaling acquired new signs and lost contact with the way of life associated with land. Carefully studied fossil finds in India, Pakistan and the Middle East, allowed to describe the evolutionary processes that led to the formation of whales. They confirm the origin of the kitiform from mesokhinia.

Whaling are water mammals that deviated greatly, both in the structure and in the way of life from their ground ancestors. They have reached huge sizes. In water, the body floats and does not need support.

Sea deposits containing the remnants of jugular (primitive whales) were found. Among them were giants with a body length of more than 20 meters.

The shape of the body is whaling

The streamlined, rounded body of the kitshaped narrows to the tail. It resembles a water drop. This allows you to much reduce the resistance from the water during movement.

The head is large, it is rounded, pointed or elongated in the form of a beak. The head department is practically connected to the body. The neck is generally very shortened, and its interception is practically absent.

In the process of evolution, the front limbs were transformed into vastshaped fins. They are used by whaling to regulate the depth of immersion, rotation and inhibition.

The body in the tail is more flat and has flexibility. The tail ends with two tail blades located horizontally.

Most types of whales have a spinal fin, acting as a stabilizer while moving. The fins on the back and tail consist of cartilaginous fabric that gives them elasticity. Swimming speed is regulated by the elasticity of the fins. Fins perform a thermoregulatory role.

There are no wool and ear shells on the body of whales. Keatoma has elastic and elastic skin. This helps to reduce friction during speed swimming.


Kitomshaped live in the waters of all oceans of the planet, and some species are in freshwater lakes and river mouths.

Also, whaling live in the seas. There are whales that prefer coastal territories, and some have chosen the waters of the open ocean. Karboxes can be found in any ocean of the globe. There are whaling, living in a certain hemisphere, for example, southern small stripes. There are animals living only in the Pacific Ocean. You can find whales in river mouths and in swamps.

Life conditions depend on the latitude of the ocean and on the change of seasons of the year. Many species migrate.


Whaling play an important role in the environmental system of the Earth. The population of a detachment of kitshaped annually is reduced at a long time.

This was influenced by the following factors:

  • violation of the environmental environment of oceans, seas, lakes;
  • City-shaped fishing in the 18-20 centuries;
  • On February 19, 1986, a ban on the fishing of whales was introduced by the International Commission for Regulation. This date is indicated in the calendar as World Whale Day.

    On the verge of disappearance were many whaling, for example, a blue whale. Most types of whaling are included in the lists of the International Red Book.
