Since late April, the world has watched a devastating oil spill from a BP drilling rig spread throughout the Gulf of Mexico and become one of the worst environmental disasters in the history of the...
Simon Coppard, a post-doctoral research fellow at the Smithsonian Tropical Research Institute in Panama and an Encyclopedia of Life Rubenstein Fellow specializing in echinoids often uncovers new...
It’s an honor to have something or someone named after you. Dr. David Pawson , Senior Research Scientist and Curator of Echinoderms at NMNH, has several genera and species, living and fossil, named...

Ochre seastars ( Pisaster ochraceus ) feed on invertebrates, such as coral and shellfish, like the mussels pictured here. The starfish forces open the shell with suction disks on the underside of its...
This bright purple sea star is a new species found by the Census of Coral Reef Ecosystems , a project of the Census of Marine Life. This particular specimen was seen on the reefs of the French...
Crinoids (echinoderms related to sea stars and sea urchins) dominate the Paleozoic shallow water habitat in this illustration. They evolved a variety of stalk heights, which enabled them to capture...
Fitting nine of anything on two fingers is impressive. These mollusks and echinoderms are a teeny-tiny sample of the ocean's biodiversity. The Census of Marine Life estimates that there are at least...
What is this bizarre, spiky-looking organism? Hint: it can be found in tropical areas of the Pacific and Indian ocean basins crawling slowly over coral reefs and devouring any living coral polyps...
This sea potato ( Echinocardium cordatum ) looks similar to its root vegetable namesake, but it's a sea urchin! The spines on this urchin are more hair-like than the spikes seen on some more commonly...
In the aftermath of the Gulf oil spill, what is the effect of oil on invertebrates like jellyfish, clams, crabs, sea stars, and plankton? The scope of the damage is more easily observed among birds...
It is a well-known fact that for animals living in the deep sea, food can be scarce. The food that is around usually rains down from above as dead animals and organic particles from plankton living...
