Faszinierende Nacktkiemer
Vorkommen, Lebensweise, Bedrohung
Nacktkiemer überleben ohne schützendes Gehäuse im Meer. Durch beeindruckende Unterwasseraufnahmen und Animationen lernen die Schüler die besonderen Anpassungen dieser Tiere kennen, etwa ihre giftigen Hautstoffe zur Abwehr von Fressfeinden. Der Film fördert das Verständnis für marine Biodiversität und regt zur Diskussion über den Schutz empfindlicher Lebensräume an.

Marine Mammals
The oceans are the home of whales, which look like fish but, in fact, are mammals like we humans and breathe with their lungs. The film shows the peculiarities of whales, which are divided into two main groups: baleen whales and toothed whales. Baleen whales, among which there is also the blue whale, the biggest of all whales, feed on tiny crustaceans called krill. Toothed whales feed on fish, crabs and other marine animals. One of the best known representatives is the killer whale, which is the fastest marine mammal with a speed of up to 55 km/h. With their leaps they delight the audiences in sea life aquariums. Whether they should be kept like that is a highly controversial issue, however. Whales are also much coveted because of their fat, meat and oil. Having been ruthlessly killed, whales have amost been wiped out and today are subject to international protection. Whale watching boosts people’s interest in these formidable animals. Another threatened animal species lives in the warm and shallow waters of Central America: the sea cows, which feed exclusively on plants and surface for breathing every 2 to 5 minutes. With the extensive accompanying material this DVD is perfectly suited for use in the classroom.
