The effect of flow speed and food size on the capture efficiency and feeding behaviour of the cold-water coral Lophelia pertusa
The capture efficiency and feeding behaviour of the cold-water coral (CWC) Lophelia pertusa (Linnaeus, 1758) were investigated considering: (1) different food types, (2) different food sizes and (3) different current speeds and temperatures. This study used two different multifactorial experimental...
