From the previous study, in all of the 124 sea stars combined, there were a total of 91 species of organisms found in their stomachs. Size-selective feeding may be attributable to the ease of manipulation and ingestion of smaller prey, which mazimizes food intake per unit time.

The A. articulatus chose to consume the smaller sized prey more often, and this is because smaller prey decreases handling time. The eastern coast of the United States is where the Royal Starfish calls home. Marine Biology Biol. The species of starfish Astropecten articulatus, commonly known as the Royal Starfish is characterized by its bold colors.

An optimization study on the feeding behavior of Luidia clathrata (Say) (Echinodermata: Asteriodea). Behavioral response of a crayfish to a fish predator. Facebook. [6] This means that when prey is present, A. articulatus alter their movement patterns so that they forage in areas with “higher prey density”, which is more evidence of the sea star foraging optimally. Some aspects of feeding ecology of the sea stars, genus Astropecten. Astropecten articulatus is indeed a voracious predator on the inhabitants of the sand bottom community. B., Lawrence, J. M.

The tube feet are cylindrical with conical ends, and the epithelium of the tube foot is covered by a thin layer of cuticle. Astropecten aranciacus (Linnaeus 1758) inhabits the Mediterranean Sea and the eastern Atlantic from Portugal to Angola, including the Canary, Madeira and Cape Verde Islands.

(1977). Also, one study investigating A. irregularis shows the same outcome, that there are more organisms in the stomachs of A. articulatus than A. irregularis, but in another study, the stomachs of both sea star species are relatively the same. That’s right, this thing has In the past, it was thought that a difference between the two species was that A. aranciaca has needle-like granules in its disk, the A. articulatus has spherical ones. 31: 312–317, Mori, S., Matutani, K.
