Novodinia antillensis perches on the branches of arboreal deep water corals, extending its arms into the
water column to catch small
crustaceans drifting past. The arms form a feeding fan, the pedicellariae grasp and secure the prey, and the arms form loops that surround the food item and take it to the mouth. On the
Cape Fear coral mound off North Carolina at a depth of around , the dominant
macrobenthos included
N. antillensis as well as the
American conger (
Conger oceanicus), the
alfonsino (
Beryx decadactylus),
sea urchins and squat lobsters (
Eumunida picta). Each species, especially the fish, had its own favoured niche habitat, often on the southern and southwestern slopes of the mound. More transient visitors to the
seamount included the shortbeard codling (
Laemonema barbatulum) and the
blackbelly rosefish (
Helicolenus dactylopterus) which were mostly found on the lower slopes and base of the mound. ==Research==
