The concentration camps, 1933-1945. The Nazis set up their first concentration camp, Dachau, in the wake of Hitlerâs takeover of power in 1933. By the end of the war, 22 main concentration camps were established, together with around 1,200 affiliate camps, Aussenkommandos, and thousands of smaller camps. In 1945, when Allied forces liberated the concentration camps at Dachau, Bergen-Belsen, Buchenwald, Sachsenhausen, Auschwitz and elsewhere, the world was shocked at the sight of images of dead bodies alongside half-dead people in these camps.
Mammals. Mammals (Class: Mammalia) are one of the warm-blooded vertebrates other than the birds. They are the most developed and evolved animals and the Class: Mammalia includes more than 4250 described extant species.
Whales, dolphins, porpoises, seals, walruses, and many other marine animals are mammals, not fish. The marine mammals exist because about 50 to 60 millions of years ago, some mammals wandered off of the land and into the ocean, and there they evolved into different types of marine mammals.hales are mammals because they share the characteristics of other mammals (like us!). These characteristics include being able to regulate their own body temperature (unlike cold-blooded animals, like lizards), growing hair and producing milk to feed their young (who are born live, not in eggs).
