Commander Remesub (Stayneger Remesub) (lat. Mesoplodon Stejnegeri) a type of whaling family of beaks (ziphiidae). In 1885, the American scientist Frederick Troy first described the marine animal of the Kluvorov family called the Commander Remesub. He is also called the stainer’s stainer, because it was Leonard Steineger, along with Zoologist Nikolai Grebnitsky, they found a mammal skull on the island of Bering. On this part of the skeleton, a description was made. Other scientists rejected the existence of the species until in 1904 the corpse of this whale in the Gulf of Yakin in the United States was discovered.
Description
This species is the most poorly understood representative. It is extremely rare. Almost all studies of their anatomy were made on the bodies of dead individuals. Most of the whales were found on the banks of the islands of Poilov, as well as the Aleutian and Commander Islands.
The Commander Remesub is a representative. After dolphins, this family is considered the largest. In the waters of Eurasia, only this species is presented.
Appearance
An adult whale has a spindle-to-use body 5-6 m long and weighing 1 to 1.5 tons. Moreover, females in size are somewhat inferior to males. They have a mediumsized pointed head, flat forehead and medium size the cordial department of the skull. The whale’s forehead smoothly passes into an elongated narrow beak. The line of the mouth is curved. The eyes are planted low.
In males, the lower jaw is very curved upward. In its front part there are a pair of flat fangs-bivnes, which are given forward a few centimeters. The females have a straight line of the mouth, so its fangs do not protrude outside.
The color of the body of the Commander’s beln and the darkness is dark, mainly gray or brown. The abdominal part, chest and lower jaw are light. Kita’s beak is also whitish. Breast fins are small and elongated. The low dorsal fin is located closer to the back of the body and slightly rejected back. The tail fin has the bent edges of the triangular shape and the excavation in the middle. The entire body of the abstract is dotted with scratches and scars of different sizes. Most likely they are traces of fights between males for the right to possess a female.
Labor
Conclusions about the habitats of the Commander Hall of the Remunitor were based on the facts of detecting fallen individuals. According to such finds, scientists have established that the armor of the abstract covers the northern part of the Pacific Ocean. It is also found in the Atlantic Ocean. In the Russian water area lives in the area of the island of Bering, the Kamchatka Peninsula, the Kuril Islands and in the Sea of Japan.

Nutrition, behavior, reproduction
By the contents of the digestive tract of the dead stains of Steiner, scientists have established their approximate diet. The whale menu includes cephalopods (deepsea squids) and salmon fish (for example, pink salmon). Just in the places of accumulation of salmon and a few meetings with this rare whale were recorded.
The Commander Remesub belongs to poorly studied species. Features of its propagation today are unknown. But it is known that they can be one alone or small groups (up to three individuals) in coastal zones, where they sail to enjoy salmon. They can also be connected to flocks from 5 to 15 whales. During movement, they follow each other a column. They go to the depths synchronously and stay under water for up to 10-15 minutes. Remeses produce a low water fountain, which can not be noticed among small waves. What these whales are sick and whether from any parasites to science is also unknown.
Red Book
The number of the population of the species was and remains a mystery to zoologists and ecologists. The commander’s abdominal has never had a commercial value. The threat to them, as well as for all marine inhabitants, is pollution of the environment. This is evidenced by those found in their muscles, liver and other internal organs accumulated in a large amount of organochlorin.
This type of beltzuba is listed in the Red Book of MSOP as a species, about which is not enough data ”. Also entered in the Red Book of Eurasia and Kamchatka as littlestudied and rare.
Interesting Facts
In the language of the Indian Maki tribe (USA), the name of the Commander Remesub sounds like “KVV-KVV-E-Acht-LE”. And the local population of the Aleutian islands gave him the name “Kigan-Agalyuzokh”.
The most famous meeting with the flock of whales of Steiner occurred in the summer of 1979 near the Aleutian archipelago. Then the whales were observed from the ship for a month. During this time, the straps appeared there seven times.
The Commander Remesub is considered a rare animal. And maybe representatives of this species lead an extremely inconspicuous lifestyle. Diving very quietly and do not emit loud bursts and other noise. If it were not for a couple of rare meetings and the whales found by people on shallows, nothing would have known about this form at all.
