Abstract
Schlangensterne in einem Tümpel der Gezeitenzone des Roten Meeres. Bewegungsweisen der Ambulakralfüße und Transport von Sandkörnchen, Verteidigung des eigenen Territoriums mit Wohnhöhle gegen Artgenossen auf Berührungsreize durch Stoßen und Schieben mit den Armen.
The film shows the animals in ebb tide pools of the tidal zone at Al-Ghardaqa on the Red Sea. The animals live stationary. Each has its own cave and any sediment washed in during high tide is removed by using the ambulacral feet as a type of conveyor belt, which creates a semi-circular heap before the caves. Cave and area in front are defended when touched by neighbouring or vagrant by pushes and pressure using the thorned aboral arms side.
