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 ...

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 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 ...

A 500-million-year-old fossil from Morocco, discovered by Natural History Museum scientists, is offering extraordinary new insights into one of evolution's most puzzling transformations: how ...

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 ...

It has long been assumed that photosensitivity in echinoderms is mainly related to diffuse photoreception mediated by photosensitive regions embedded within the dermis. Recent studies, however, have ...

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 ...

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 ...
