Hunters and Healers. The Secret Life of Sea Snails / Wunderschön aber giftig. Das geheimnisvolle Leben der Meeresschnecken

Beschreibung

The world's first ever comprehensive depiction of the mysterious life of sea snails. See how these unique animals live, hunt and reproduce, and learn about their great importance in the field of medicine. Hunting Techniques: For such a primitive life form, the sea snail displays an astonishing array of hunting strategies, along with an extraordinary olfactory organ with which they can detect sleeping prey over vast distances across the sand and gravel of the sea floor. Viewers will witness dramatic scenes of cone snails (Conidae) pursuing their quarry using these techniques. Reproduction and Parental Care: Observe never before seen images of the parental behaviour of the cowry (Cypraeidae), who protect their eggs until they hatch, then care for them until they are ready to fend for themselves in the open sea. Equally rare is the footage of various cone snails laying eggs. Medical Significance: Follow us into the world of venomous sea snails, whose impact on the future of medicine is becoming ever greater. Exhibiting analgesic and anaesthetic properties, the venom of some sea snails can also be used to combat Alzheimer's disease, senile dementia and other chronic diseases.
