Sampling stations in the Sylt Outer Reef area (green outline) in the southeastern North Sea and target species below. Red circles highlight the sampling stations where the fishes were caught. Drawings of the species studied here can be seen below the map. The map was created using the free and open source QGIS (v 3.38.3-Grenoble, https://qgis.org). Fish illustrations were based on self-made photographs of the studied specimens and were drawn and provided by Jessica Van der Maesen.
