Scientists Have Finally Found 'Waldo'
2013-07-16 09:36:46

Pensoft Publishers After nearly 25 years of searching, three scientists have finally found Waldo. No, not the loveable bespectacled character in children's picture books, but rather an unusual clam discovered off the coast of California and British Columbia. Paul Valentich-Scott from the Santa Barbara Museum of Natural History, and Diarmaid O Foighil from the University of Michigan, Museum of Zoology first began discussing this unusual clam back in 1989. Valentich-Scott discovered his...

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...

purple sea urchin Strongylocentrotus purpuratus
2013-04-11 05:15:28

Alan McStravick for redOrbit.com - Your Universe Online The purple sea urchin (Strongylocentrotus purpuratus) has been receiving a bit of attention lately on the pages of redOrbit and in academic journals. As it turns out, this sea creature is particularly efficient at adaptive success. redOrbit´s own Lee Rannals wrote yesterday about how this spiny creature seems suited to a future where climate change plays a significant role. And today, we learn that even in their youngest state,...

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 Origins Of Modern-day Deep-sea Animals Suggested By New Fossils
2012-10-11 08:18:53

A collection of fossil animals discovered off the coast of Florida suggests that present day deep-sea fauna like sea urchins, starfish and sea cucumbers may have evolved earlier than previously believed and survived periods of mass extinctions similar to those that wiped out the dinosaurs. The full results are published Oct. 10 in the open access journal PLOS ONE by Ben Thuy and colleagues from the University of Göttingen, Germany. Previously, researchers believed that these...

Sea Urchin Spine Structure Makes It Strong And Fragile
2012-10-03 16:46:09

Lee Rannals for redOrbit.com - Your Universe Online Sea urchins are those round little spiky creatures in the ocean, and a study published in the journal PLOS ONE has unveiled what it is that gives those viscous looking spines their unique characteristics. For years, scientists have been interested in the chemical composition of the sea urchin spine, but there has been no investigation of how they respond to mechanical stress. The purple-spined sea urchin is found in tidal waters...

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...

April Flowers for redOrbit.com - Your Universe Online How can sea otters change the world? A new study, led by the University of California, Santa Cruz, suggests that a thriving population of sea otters will keep the sea urchins in check, which will in turn allow kelp forests to prosper.  Spreading kelp forests can absorb as much as 12 times the amount of CO2 from the atmosphere than if it were subject to sea urchin ravaging. "It is significant because it shows that animals can...

Purple Sea Urchin Metamorphosis Controlled By Histamine
2012-04-27 07:06:53

Now that hay fever season has started, sufferers are well aware of the effect of histamines. However it is easy to forget that histamine is also a neurotransmitter involved in controlling memories, regulating sleep, and controlling secretion of gastric acid. New research published in BioMed Central's open access journal BMC Developmental Biology shows that for the purple sea urchin (Strongylocentrotus purpuratus) histamine is also responsible for controlling metamorphosis from a free swimming...

Structure Of Tough Sea Urchin Spines May Inspire Engineers
2012-02-16 14:10:27

A team of German scientists recently decoded the molecular structure of the unusually sturdy spines of sea urchins, a discovery that they believe could eventually prove useful in helping engineers construct stronger, more stable buildings. Biologists have long known that the spines of the globular little marine animals are made of the compound calcium carbonate, a chemical commonly found in the shells of various invertebrates, not to mention egg shells, calcium supplements and the antacids...

Diadema setosum
2013-11-21 12:27:30

Diadema setosum is a species of long-spined sea urchin in the family Diadematidae. It’s a typical sea urchin, which exceptionally long and hollow spines that are mildly venomous. D. setosum is different from other Diadema with five distinctive white colored dots that can be found on its body. The species is located throughout the Indo-Pacific region, from Australia and Africa to Japan and the Red Sea. Although it is capable of painful stings when stepped upon, the urchin is only somewhat...

Eccentric Sand Dollar, Dendraster excentricus
2013-11-21 12:20:48

The Eccentric Sand Dollar (Dendraster excentricus) known also as the Sea-Cake, Biscuit-Urchin, Western Sand Dollar, or the Pacific Sand Dollar, is a member of the order Clypeasteroida, better known as sand dollars, a species of flattened, burrowing sea urchins located along the Pacific Ocean from Alaska to Baja California. This species is an irregular echinoid that is flattened and burrows into the sand, unlike the regular echinoids, or sea urchins. It can be found living within the...

Red Sea Fire Urchin, Asthenosoma marisrubri
2013-11-21 12:03:03

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...

Echinus tylodes
2013-11-15 10:51:41

Echinus tylodes is a species of sea urchin belonging to the Echinidae family. It’s white with rather sparse pink colored spines and is native to the eastern coast of North America including the Gulf of Mexico. This species has a sub-globular test that is about two-thirds as high as it is wide and grows to a diameter of 4 inches. The joints that are between the ambulacral plates and the pores through which the tube feet project are both sunken below the general surface of the test. The...

Ophiocoma scolopendrina is a species of brittle star in the family Ophiocomidae. Ophiocoma scolopendrina, similar to other brittle star, have long and thin arms stemming from a small dish-shaped body and are around the size of an outstretched human hand. They belong to the phylum of echinoderms, which incorporates sea urchins, sea stars, and sea cucumbers. Dorsal disc and dorsal arm plates vary from black, multicolored black to a pale brown. The arms are abnormally banded. They can...
