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 ...

Rachael has a degree in Zoology from the University of Southampton, and specializes in animal behavior, evolution, palaeontology, and the environment. Rachael has a degree in Zoology from 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 ...

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 ...

This exercise illustrates the two major features that all members of the Phylum Echinodermata have in common - the water vascular system and pentaradial symmetry. The take home message is that all ...

Fossil echinoderms, including the common Cambrian and Ordovician echinoderms figured here (Fig. 1 from Deline, et al., 2021; request permission to use here) have a rich and diverse fossil record.

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 ...

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 ...

This collaborative studentship is potentially funded by the University of Reading as part of a strategic partnership to support innovative collaborative research between the University and the Natural ...
