Snails and Their Habitats
Biodiversity and Survival Strategies
They are slow, really slow … they are soft, they are slimy …and greedy.
Most of us look at them with disgust. But snails and their relatives are fascinating, useful animals and true survivors.
Snails and slugs live on land, in freshwater and in the sea. They have been crawling across our planet for more than 500 million years.
The number of species is a matter of estimation. Biologists assume there are up to 100,000. In Germany, their number is limited with about 180 species. Nevertheless, surprisingly little is known about the mode of life of terrestrial snails although some species are very conspicuous.

Resuscitation
It can happen to anyone – of any age, in any place, at any time. Sudden cardiac arrest may quickly prove fatal. Immediate action is called for! Just remember: Check Call Press Anyone can do it. You can't do anything wrong!
Product Piracy
Counterfeiting takes place in almost all economic sectors – textiles, watches, car parts, machine parts, tools, accessories, software and medicines. Some counterfeits are easy to recognise, others are so well-executed that even experts have difficulty distinguishing between original and imitation. This DVD covers the development of a product from idea to manufacture. Once a product has become a trademark, product pirates appear on the scene.
Rights and Obligations
Three girls of different ages: Anna is 17, Paula 15 and Lena 13. Before the law, their respective ages have consequences – because children and adolescents have different rights and also obligations.
