Slender Starfish, Astropecten bispinosus
2012-04-19 11:01:50

The Slender Starfish (Astropecten bispinosus), is a species of sea star in the Astropectinidae family. This species lives only in the Mediterranean Sea and prefers sandy seabed near meadows of Cymodocea nodosa. It is found at depths between 8 and 400 feet. While sandy seabeds are preferred, it can also be seen on muddy and gravely mobile seabed as well. It remains buried during the day. This sea star has very narrow and high superomarginal plates with a bare area on the vertical face...

The Spiny Comb-star (Astropecten irregilaris), is a species of starfish in the Astropectinidae family. It is found in the Atlantic Ocean and the Mediterranean Sea. It lives on mobile seabed (sandy, muddy or gravely) and remains buried under sediment during the daytime. It is a very common species in all kinds of mobile seabed from 4 to 4,000 feet deep. It is active in the late afternoon and at night. Specimens from the Atlantic and Mediterranean show differences in the superomarginal...

The Common Starfish (Asterias rubens), also known as the Common Sea Star, is the most common species of starfish found in the northeast Atlantic Ocean. It is usually found on rocky and gravelly substrate. This starfish has five arms and usually grows to between 4 and 12 inches in diameter, although some specimens have been recorded up to 21 inches across. It is typically orange or brown in color, but sometimes can be yellow, white, blue, purple or green; deep-water specimens are paler....

Gorgonocephalus eucnemis is a species of starfish found in circumpolar marine environments in the Northern Hemisphere, particularly the Arctic Ocean and northern parts of the Atlantic Ocean as far south as the Faeroe Islands and Massachusetts Bay. It also occurs in the Pacific Ocean from the Bering Sea south to Japan and Laguna Beach, California. It is found in rocky areas with strong currents at depths down to 6,600 feet, but more commonly at 50 to 500 feet. It is also found on mud and sandy...

Astropecten platyacanthus is a species of sea star of the family Astropectinidae. It is found only in the Mediterranean Sea living on mobile seabed (sand, mud or gravel) remaining largely buried under the sediment during the daytime. It comes out in late afternoon and is active throughout the night. It can be found at depths between 3 and 200 feet, but is more frequently found in mixed coarse sand and mud at depths of 3 to 12 feet. This starfish has narrow and high superomarginal plates,...
