Human beings are not a prey species for sharks and have never been "eaten" by them. Fatal injuries caused by shark bites (fewer than 10 worldwide per year) are solely caused by cases of mistaken identity, accidents or behaviour which antagonizes the animals.

These cartilaginous fish are predators which have adapted perfectly to their environment. Their principal diet is fish, although great white sharks also hunt seals and other aquatic mammals with high-fat flesh.
While sharks hunt solely to eat, they are not constantly in pursuit of prey. Sharks are thus by no means the voracious monsters of popular belief. They can survive for long periods without eating - further proof of their superb survival skills.
Sharks do not excrete urine, so that uric acid accumulates in their flesh. To render their meat edible, it must be subjected to fermentation. In addition, shark meat always has high levels of methylmercury contamination - a neurotoxin which attacks the human central nervous system.
Unfortunately, shark meat is also available in Germany - but under a different name. "Seeaal" (sea eel) and "Schillerlocken" are common trade names for the meat of the spiny dogfish (squalus acanthias).
