Abstract: | In a feeding experiment, 16 individuals of Astropecten aranciacus were kept in two enclosures on the sea floor, and were provided with a surplus of food. Feeding at a daily rate of 1.3% of their dry tissue weight, their food intake was four times higher than that of free-living sea stars. The periods of daily activity were shorter than in control individuals kept in enclosures without additional food. |
