Steller's sea cow, Steller's sea cow or Riesenseekuh (Hydrodamalis gigas), formerly known as scabs animal, an extinct sea cow of the Northern Pacific. It was in 1741 by German physician and scientist Georg Wilhelm Steller first described scientifically, after the expedition ship for Vitus Bering who was today named after him stranded Bering Island off Kamchatka. At the time there were probably only about 2,000 copies in the Bering Island and the neighboring island of copper. The last animal of the species was probably killed in 1768 by fur hunters in the Bering Island.
features
Today's knowledge based on the meticulous descriptions of posts and a number of skeletons in various museums.
The animal was up to 8 feet long and about 4 tons. The teeth had receded completely, the animal rubbed its seaweed food between two horny Kauplatten. The front arms ended in stunted metacarpal bones, finger bones, the animal had not. Of the two hind limbs vestigial pelvic bones remained. The animal had asked a cross, forked tail fin of almost 2 meters wide. The skin was several inches thick and had a bark-like consistency, hence the name Borken animal. The color was dark brown.
the only manatee living in historic times was a resident of this kind of cold water. In the Bering Sea algae were the food of Steller's sea cow. The teeth had receded completely in adapting to these soft food, and the crushing of the food was taken solely by the horny plates lined with taste buds. The front rudder fins were reduced compared with those of other manatees strong.
Evolution
was probably as a result of Erdabkühlung about 20 million years ago a side branch of dugongs out, the hydro Dama Lina. In the Miocene the genus Dusisiren that represented this subfamily, was widespread in the Pacific. From the Pliocene and Pleistocene Hydrodamalis three species of the genus are known, the Steller's sea cow in the development ended.
dissemination
The Steller's sea cow once inhabited the shores of the northern Pacific Ocean from Mexico to the Aleutian Islands to northern Japan. Maybe they drove the hunting by people hostile to the edge of their habitat, where it was eradicated after the discovery by Bering's crew in just 27 years due to excessive hunting.
Exhibits
While the world still about 20 skeletons there are only two pieces of skin of Steller's sea cow known. One of them is in the Zoological Museum in St. Petersburg, the other is shown on the Bremen Overseas Museum. Skeletons can be seen in the German speaking in the Japanese Palace in Dresden Museum of Ethnology (also a model), the Natural History Museum in Braunschweig and at the Natural History Museum in Vienna. In the Museum at Stuttgart Rosenstein, there is a skull cast and a small model.
