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 ...

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 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 ...

Researchers in Japan have finally observed living larvae of a sea lily, a marine invertebrate with a 500-million-year fossil record. The finding supports a century-old hypothesis about how the ...

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 ...

After more than a century of intensive study, scientists have assumed that larvae of non-parasitic invertebrates reproduce only very rarely, but new research by University of Alberta scientists ...

A hallmark feature of echinoderm larvae is the development of the left anterior coelom. This coelom, called the axohydrocoel, consists of the morphologically distinct, but undivided, left axocoel and ...

Like many other echinoderms (Echinodermata), brittle stars can regrow body parts. Some species also have the ability to reproduce asexually (fissiparity). This means that the animal divides and two ...

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 ...

This is a preview. Log in through your library . Abstract Commensal shrimps associated with echinoderms, molluscs, and coelenterates were collected in Tayrona National Park northeast of Santa Marta ...
