They estimate that the global production from all echinoderms is over a tenth (0.1) of a gigatonne of carbon per year -- that is, more than a hundred thousand million kilograms. This is less than ...

Major findings on the inner workings of a brittle star's ability to reversibly control the pliability of its tissues will ...

While studying zoology at his native New Zealand’s Victoria University in Wellington, Pawson chose to focus his research on echinoderms, a group of marine invertebrates that includes sea stars ...

Echinoderms such as starfish are unusual for their five-fold body symmetry. Maps of gene-expression patterns show how this body plan was acquired, and that the genes specifying head structures do ...

Most eulimids are highly specialized and exclusively ectoparasitic (external parasites) on echinoderms. Most are permanently attached to a single host, although some species may transfer between hosts ...

Now researchers have gotten their first-ever look at similar tentacle-like structures in an extinct group of these echinoderms. It was suspected that the ancient marine invertebrates, called ...

Souza compared it to a wok cover. Since then, he's had to become a fashion designer of sorts for the echinoderms (a phylum including sea urchins, starfish and sea cucumbers), tailoring cowboy ...
