Abstract
Die Brustflossen des abgeplatteten Nagelrochens sind spitz auslaufende Flossensäume, die in wellenförmiger Auf- und Abbewegung Vor- und Auftrieb bewirken. Teilweise Zeitdehnung.
The pectoral fins of the flatted thornback ray show spiky fin edges whose undulating up and down movement cause propulsion.
