Mysterious Wasting Virus Killing Starfish Along West Coast
2013-11-04 15:04:27

Brett Smith for redOrbit.com - Your Universe Online California marine biologists are reporting the spread of a mysterious bacteria that is killing starfish up and down the West Coast – transforming the echinoderms into piles of goo in the process. “They essentially melt in front of you,” Pete Raimondi, a biologist at the University of California, Santa Cruz, told The Santa Rosa Press Democrat. The affected animals form white lesions on their exterior that grow and occasionally...

Mass Star Fish Die Off
2013-09-11 10:09:02

redOrbit Staff & Wire Reports - Your Universe Online Massive numbers of dead starfish have been observed in the waters around Vancouver, British Columbia over the past two months, and scientists are currently at a loss as to the possible cause of the fatal phenomenon. Jonathan Martin, a research associate at Simon Fraser University, has observed the mass die-off of both Sunflower seastars (Pycnopodia helianthoides) and morning sun stars (Solaster dawsoni) and has published photos...

Can You Stomach This? Starfish Feeding Secrets Revealed
2013-08-02 14:13:12

[ Watch the Video: Starfish Feeding Mechanism Better Understood ] Brett Smith for redOrbit.com - Your Universe Online Starfish have a feeding method that is unlike any other. To eat, the echinoderm ejects its stomach from its own body -- placing it over the digestible parts of its prey, typically a mussel or clam. The stomach then partially digests what it can, producing a chowder-like slurry that is then drawn back into the starfishes' ten digestive glands. According to a new report...

Starfish Have Primitive Eyes Used To Navigate Their Environment
2013-07-05 09:01:37

Society for Experimental Biology A study has shown for the first time that starfish use primitive eyes at the tip of their arms to visually navigate their environment. Research headed by Dr. Anders Garm at the Marine Biological Section of the University of Copenhagen in Denmark, showed that starfish eyes are image-forming and could be an essential stage in eye evolution. The researchers removed starfish with and without eyes from their food rich habitat, the coral reef, and placed them...

Purple Urchins Quickly Adapt To Acidic Oceans
2013-06-13 11:41:25

Brett Smith for redOrbit.com - Your Universe Online As the levels of atmospheric carbon dioxide increase, the oceans are projected to absorb more of the greenhouse gas, leading to acidification of the water. This shift in oceanic chemistry is expected to negatively impact countless species. However, a new study from the University of California, Santa Barbara has found that purple sea urchins Strongylocentrotus purpuratus are capable of evolving in a way that copes with potential...

Sea Urchins Prepared For Future Climate Change
2013-04-10 05:47:43

[ Watch the Video: Ocean Babies on Acid - The Time Machine ] Lee Rannals for redOrbit.com - Your Universe Online Scientists have uncovered some surprising abilities in sea urchins living along the coast of California and Oregon. A group from Stanford discovered that some purple sea urchins have the ability to rapidly evolve in acidic ocean water, which is a skill that could come in handy as climate change increases. This ability allows urchins to have healthy growth in water with...

Ancient Fossilized Sea Creatures Contain Oldest Biomolecules Taken Directly From A Fossil
2013-02-19 13:45:53

The Ohio State University Though scientists have long believed that complex organic molecules couldn´t survive fossilization, some 350-million-year-old remains of aquatic sea creatures uncovered in Ohio, Indiana, and Iowa have challenged that assumption. The spindly animals with feathery arms–called crinoids, but better known today by the plant-like name “sea lily”–appear to have been buried alive in storms during the Carboniferous Period, when North America...

Secrets Of Looking Young Could Come From Sea Creatures
2012-10-02 11:16:07

April Flowers for redOrbit.com - Your Universe Online A research team at Queen Mary, University of London reports that sea cucumbers and sea urchins could hold the secret to looking young. Published online in both PLoS One and General and Comparative Endocrinology, the study looked at the genes of echinoderms, such as sea cucumbers and sea urchins, because they are able to change the elasticity of collagen within their bodies. The scientists found the genes for peptides, known as...

2012-08-20 12:37:24

redOrbit Staff & Wire Reports - Your Universe Online The appearance and ecology of Atlantic coral reef habitats could be altered by yellow brittle star A study co-written by Dr. Gordon Hendler of the Natural History Museum of Los Angeles County (NHM) about an invasive species of brittle star, Ophiothela mirabilis, has been published online in Coral Reefs, the Journal of the International Society for Reef Studies. Growing populations have established themselves at distant points in...

The Red Sea Fire Urchin or Toxic Leather Sea Urchin (Asthenosoma marisrubri) is a relatively common sea urchin with a widespread distribution within the Indo-Pacific, and was, until 1998, considered a color variant of Asthenosoma Varium. Sea urchins are close relatives are crinoids, brittle stars, sea cucumbers, and starfish, all being echinoderms. This species grows to 25 centimeters in diameter, with articulated plates making the test quite flexible. It prefers water temperatures between...
