Finwal Description

The body length of an adult finwal is from 18 to 24 m in the northern regions, and from 20 to 27 m in the south of the animal distribution range. Females of this species are larger in size than males, but their weight is approximately the same and amounts to 40-70 tons. In general, finials are more slender and lighter than blue whales, but they are not inferior to the latter in terms of body length. And their average weight is even less than that of the bowhead whale and sperm whale.

The finwel's back is painted in dark gray or dark brown color, belly and fins on the underside of white. Finwala is fairly easy to distinguish by the asymmetric color distribution on the front of the body: the lower jaw is white on the right side, and dark on the left side. A similar coloration is characteristic of the whalebone of this animal. But the color of the mouth and tongue is the opposite. From the lower jaw to the navel, folds of skin are located.

Features of finwal nutrition

The basis of the finwal diet is crustaceans, the so-called krill, as well as small fish - herring, sardines, capelin, anchovies, pollock. An adult finwall eats about 2 tons of food per day. The average speed of the finwalk during the hunt is 11 km / h. When an animal finds a school of fish, it circles around it at high speeds, as a result of which the flock forms a dense pile of large sizes. Then the finwal is laid on its side so that it is convenient to swallow the prey, opens its mouth and eats.

Food falls into the mouth of a whale with water. At one time, he swallows about 10 kg of krill or fish in this way. After the animal closes its mouth and with the help of its tongue pushes water out. It seeps through the whalebone, while fish and krill remain on it. Finwal licks them with his tongue and swallows.

The whalebone finwale contains approximately 450 plates on each side of its mouth. One such plate is 76 cm long and 30 cm wide. A fringe is located along the edge.

Finwal food takes about 3 hours of time per day. In cases where there is little food, the whale searches for it all day. It submerges under water for a maximum of 10-15 minutes, and before the next dive, it necessarily floats. In general, hunting for finwala is a difficult and troublesome business.

Finwal Spread

Finwal is common everywhere in the waters of the oceans, except for coastal areas. In winter, animals move to the subtropical region, in warm latitudes, where mating and birth of offspring takes place. In the summer, migration to cool arctic and antarctic latitudes takes place with the aim of obtaining food. Since the seasons do not coincide in different hemispheres, the finwala populations that live in the north and south usually do not overlap.

Common Finwal Subspecies

Scientists distinguish two subspecies of finials, which differ slightly in appearance and in the nature of the issued signals: these are the North Atlantic finials (Balaenoptera physalus physalus) and the Antarctic finials (Balaenoptera physalus quoyi - pictured). Previously, the third North Pacific subspecies was also identified. The southern finwale is usually 10% larger in size than the north.

Finwal behavior

Finals can lead both a solitary lifestyle and live in small groups, up to 6 goals. Large groups are rare, and usually form only when a lot of food appears in the habitat. Finwales move faster and dive deeper than other large whale species. The maximum speed of this species reaches 50 km / h, immersion depths exceed 230 meters. A whale can dive under water for 15 minutes. Finwail dives into a deep arc in depth, bends at the same time and raises its tail high above the water. The fin located on the back is shown after immersion of the head. After each immersion in water, the animal emerges to the surface and finds itself dense, conical, up to 6 m high fountain.

Finals communicate with each other using low-frequency sounds. Whales talk, even when they are hundreds of kilometers away. When mating takes place, sounds are made exclusively by males, which serves to attract females. Recently, there has been an increase in the level of oceanic noise due to increased shipping, and the birth rate has been declining at the finals, as it becomes difficult for a male to attract a female.

Finwal Reproduction

The mating and childbearing processes at the finals occur throughout the year, most intensively in the winter, when whales migrate to warm waters. Usually, females give birth to one baby in 2-3 years. Pregnancy lasts 12 months, after which the young are born, in the fall, after arriving at the winter. The dimensions of the newborn in length reach 6-7 meters, the weight is about 1800 kg. During the first six months of life, the female feeds the cub with milk. During this time, it grows and manages to reach 10-12 meters in length. Finwal puberty occurs in 6-10 years, but after that the whale continues to grow. This species lives in nature for over 100 years.

Finwal's Natural Enemies

Finwala is distinguished by a rather high speed of movement in the water and the habit of living far from the coast, so people could not hunt for this species for a long time. But at the end of the 19th century, man acquired the technical capabilities for this industry. Prior to this, the blue whale was considered the most valuable prey in the whaling business, but after its population was almost completely destroyed, people began to hunt finials on a large scale. In 1938 alone, about 28,000 individuals were killed in southern waters. The situation developed in the same spirit until the end of the 1960s, and the finwala population was also on the verge of extinction. After that, the extraction of the species was prohibited until the restoration of the species abundance. The Icelandic government once again allowed the finwal hunting ten years ago.

The finwale population before its extermination was about 400,000 southern and 70,000 northern animals. The decline in the population as a result of fishing has left about 5,000 individuals alive. For this reason, the species remains rare today, although the number of finals in the south has grown to 15,000, and in the north of the region is estimated at 40,000 goals.

Interesting facts about the finwale:

  • Finals are also known as herring whales, common minke whales, herring minke whales, true whales. This species is a close relative of blue whales and the second largest animal on our planet. Finwales and blue whales are so similar and related that hybrid individuals of these two species of mammals are even found in the ocean.
  • For the first time, the scientific description of the finwal was given by the scientist Frederick Martens in the middle of the 17th century, and a little later it was repeated by Paul Dudley in the beginning of the 18th century. It was these data that Karl Linney took as a basis.
