Astropecten Cingulatus
''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 pr ...

Astropecten Aranciacus
''Astropecten aranciacus'', the red comb star, is a sea star of the family Astropectinidae. It is native to the east Atlantic Ocean (Portugal to Angola) and Mediterranean Sea. Habitat and behaviour ''Astropecten aranciacus'' lives very near the coast, and at low tide it buries itself in the sand, showing only the centre of its upper side which is swollen in the form of a cone. This cone acts like a sense organ. When it is touched, the cone contracts and the starfish buries itself on the sand again. Then at high tide, the starfish reappears on the surface of the substrate. It buries itself in the sand to shield parts of its body from the rays of the sun, especially the bottom surface which has no coloured pigment and is therefore particularly sensitive. ''Astropecten aranciacus'' lives on sandy, muddy or gravel bottoms at depths of . This species is active and easy to find in the late afternoon and during the night. Description This starfish has superomarginal plates equipped with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
