If present in high numbers Amphiura filiformis provides an important link between the benthic and pelagic environments because it seems to be important in the diets of many fish and invertebrate predators including dab Limanda limanda, haddock Melanogrammus aeglefinus and Norwegian lobster Nephrops norvegicus (Baden et al., 1990). These predators do not generally consume the entire brittle star but crop only the arms, which are later regenerated. An energy budget estimated for the Amphiura filiformis population of Galway Bay suggested that arm regeneration contributed significantly to the total annual production of this species (O'Connor et al., 1986).
