Latest Sea star Stories
The appearance and ecology of Atlantic coral reef habitats could be altered by yellow brittle star
How quickly can new species arise? In as little as 6,000 years, according to a study of Australian sea stars.
As planktonic organisms the larvae of the marine annelid Platynereis swim freely in the open water.
A team of scientists has combined embryological observations, genetic sequencing, and supercomputing to determine that a group of small disk-shaped animals that were once thought to represent a new class of animals are actually starfish that have lost the large star-shaped, adult body from their life cycle.
Scientists have discovered that one species of starfish has a remarkable strategy to avoid overheating in the sun.
Large numbers of starfish have been showing up in southern New England this year, blanketing the seafloor and washing up on beaches, observers say.
Canadian zoologists have determined elevated water temperatures and high carbon dioxide concentrations can boost the growth of a species of sea star. The University of British Columbia scientists said their study is one of the first to look at the impact of ocean acidification on marine invertebrates that don't have a large calcified skeleton or external shell.
New research by UBC zoologists indicates that elevated water temperatures and heightened concentrations of carbon dioxide can dramatically increase the growth rate of a keystone species of sea star.
No-take marine reserves where fishing is banned can have benefits that extend beyond the exploited fishes they are specifically designed to protect, according to new evidence from Australia's Great Barrier Reef reported in the July 22nd issue of Current Biology, a Cell Press publication.
While studying eight Macquarie Ridge sea mountains scientists have discovered millions of starfish capturing food.
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,...
