Echinoderms, such as starfish, sea urchins and sea lilies, use small, flexible, tubular projections called "tube feet" for ...

Rapid morphological evolution in early echinoderms was later outpaced by increases in ecological diversification, indicating the phylum exhibited morphological volatility and ecological constraints at ...

The conservation of genome regulatory elements over long periods of evolution is not limited to vertebrates, as previously thought, but also in echinoderms (invertebrates). This is one of the most ...

The recent Invertebrate Wars reminded me of spectacular, but often ignored, group of gastropods. The parasites! This is a group that I have totally geeked out on in the past. In my previous work I ...

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 the ...

The impact on levels of carbon dioxide in the Earth's atmosphere by the decaying remains of a group of marine creatures that includes starfish and sea urchin has been significantly underestimated.

Echinoderms are one of the most highly derived groups of animals with many species as significant components of several marine communities. They’re classified by three fundamental shared ...

The evolution of the sea star, sea urchin, and other echinoderms’ body shape during the Cambrian and Ordovician periods was faster and more dramatic than their ecological innovation, according to a ...

The impact on levels of carbon dioxide in the Earth's atmosphere by the decaying remains of a group of marine creatures that includes starfish and sea urchin has been significantly underestimated. The ...

define the term adaptation. describe adaptations of sea stars. explain how adaptations of animals enable them to survive in different environments. Sea stars, sea urchins, sand dollars and sea ...

Sea stars and their relatives eat, breathe and scuttle around the seafloor with tiny tube feet. Now researchers have gotten their first-ever look at similar tentacle-like structures in an extinct ...
