Schlangenstern. Die diatomeen- und algenreiche Schaum- und Staubschicht des Flutwassers wird durch spiegelbildliche, aber synchrone Schlängelung von 2 bis 3 Armen zu den Ambulakralfüßchen getrieben, die die Nahrung einschleimen und als Nahrungswulst gegen den Mund schieben.
The foam and dust film of the flood water is rich of diatoms and algae. The brittle star drives the water through synchronous meandering of 2 to 3 arms to its ambulacrals that cover the food with slime before leading it to the mouth.
