Astropecten Nitidus
''Astropecten'' is a genus of sea stars of the family Astropectinidae. Identification These sea stars are similar one to each other and it can be difficult to determine with certainty the species only from a photograph. To have a certain determination, in some cases, animals should be analyzed in the laboratory or using genetic testing, but often it isn’t possible. In order to determine the species, with a reasonable margin of error, it’s necessary to observe the appearance of the animal, in particular, based on some typical features described by principal authors that have analyzed over the years a large number of specimens in the laboratory. The main elements, to determine the various species from photo, are: the appearance of the dorsal marginal plates and spines, the size, the shape of disc and arms. For a good identification by sea photo it is important to take a complete picture of all the subject, a picture of the detail of the marginal plates and to measure as pre ...

Astropecten Bispinosus
''Astropecten bispinosus'' is a sea star of the family Astropectinidae from the Mediterranean Sea. Habitat and behaviour Starfishes of genus Astropecten live on mobile seabed (sandy, muddy or gravel seabed) and they remain largely buried under sediment during the day. During the late afternoon and during the night starfishes go out to hunt mainly Bivalvia, bivalve molluscs, which are their favourite preys. This species lives only in the Mediterranean Sea and it prefers sandy seabed near meadows of ''Cymodocea nodosa'' and it lives at depths between 2 and 100 m. This species is active and easy to find especially in the late afternoon, but sometimes it is possible to find it during the day or during the night. Description This sea star has very narrow and high Astropecten, superomarginal plates with a bare area on vertical face of them (visible in the lateral side of Astropecten, arms between Astropecten, inferomarginal spines and Astropecten, superomarginal spines). Every superoma ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Astropecten Articulatus
The ''Astropecten articulatus'', more commonly known as the Royal Starfish, is a West Atlantic sea star of the family Astropectinidae. Description The Royal Starfish is characterized by its bold colors. It has a purple granulated disk, which is the central region of the sea star, and the purple color continues to extend to its five arms. The margin of the sea star, which is its outline, is an orange color. Entomologist Thomas Say describes the sea star's margin as “articulated throughout”, meaning that the orange margin that surrounds the sea star is continuous, even at the joints of its rays. It also has white spines that are attached to the orange margin and tube feet at the ends of its rays. The tube feet are cylindrical with conical ends, and the epithelium of the tube foot is covered by a thin layer of cuticle. Underneath the epithelium is the nervous tissue, and underneath that are fibrous tissues in the form of both left and right helices which protect the sea sta ...
