| Anmärkningar | Favours a sediment-free rocky habitat, where it stays in midwater about one meter away from the substrate. Is normally found just below the surface, rarely deeper than 5 m. Mostly seen at places where the rocky coast drops steeply. Feeds on invertebrates taken from the water and on insects that fall into the water. |
