co exception of the back-whale is put all other types of the furrow-whales into a common type Balaenoptera or Finnwale, since its body-forms - apart from the size - resemble the shape of the Finnwals strongly.
Shape The Finnwal can reach short-term with its long-stretched, streamlined body top-speeds of up to 48 km per hour. The flippers are quite small and pointed in the relationship to the usually 18-20,5 m long body, while that is trained well triangular back-Finn. The torso is compressed in its rear part at the side, and the mighty tail-flukes position directly at this powerful muscleman without thinner transition.
The body-upper side is colored dark-gray, the stomach-side of it whitish, however the border near the Finnwal proceeds asymmetrically in the contrast to its near relatives. The left lower jaw-part also is dark, from-colored the right side "as planned" white, however. In the mouth-interior, inverted behaves exactly; also the approximately 370 Barten (until 90 cm long) show differences: they are left-side all gray until black, knows right on the other hand in the front and colored again behind right gray-black.
Old Finnwale (valued maximum-age 30 years) can become up to 24 m long in exceptions.
Reproduction In the birth (June / July), these whales already are 6,5 m long after all. The Tragzeit amounts to 111/4 months, the young are cured after 6 months, they already then are 12 m long. Finnwale with 5-6 years (with 19-20 m of length) become sexually mature, while it only in the age of 15 years and to grow over it stops. The combination-time is with the Finnwalen of the southern hemisphere in the time of April until August, with the North-Pacific animals against it from November until January. For usually lie between two consecutive births somewhat more than 2 years of pause; one estimates that a dam - if not it already before the sexually mature (length approximately 20 m)!) by whalers, it is shot - 12 calves in the course of its life can raise. Most of the carried off Finnwale are however only approximately 18 m long - therefore not yet sexually mature! - and weighs 50 t.
Way of life Finnwale live together sociably in troops of no usually more than 5 animals and immigrate from its winter-quarters in warm restrained widths in the spring the food-hands polar-waters, where they live on the Krill in the most important thing. The Finnwale of the North-Atlantic catch however also preferred fish, usually herrings (Clupea harengus) and Lodden (Mallotus villosus), why one calls also "herring-whale" it.
The Finnwal dives until in depths of 300 m and can remain under water approximately 10-15 minutes.
Whale-catch Finnwale were the most important raw material-reserves after the almost total annihilation of the blue whale for the whale-catch-industry. The history of its Massenabschlachtung resembles the fate of the blue whales. Also here there was not any understanding of the consequences of unlimited Bejagung so that Finnwale are threatened in several areas today. The Finnwale amounted still to 1956 80 percent of the altogether landed "Walrohmasse." Annual became in that time between 20 000 and 30 000 (!) these second-biggest whales killed. Also like the other types of the furrow-whales, Finnwale Blubber (bacon), muscle-meat and bones deliver approximately in the same composition as blue whales so that the industry didn't have any changeover-problems. With a length more inferior by only approximately 15 percent, 1 Finnwal deliver Rohmasse like 1 blue whales however only half so much. A "blue whale-unit", the old measurement-number for the comparable oil-profit of different types, amounted to 1 blue whales or 2 Finnwale, as well as. 2,5 back-whales or 6 Seiwale.
Continuance in 1986, the international whale-catch-commission enacted a total prohibition of commercial catches. The continuance on the southern hemisphere only includes one quarter of the original continuance approximately today and is estimated at 85 000-100 000 animals. On the northern hemisphere, one only assumes a continuance of approximately 20 000 animals in the comparison to originally approximately 60 000 copies today.
