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 ...

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 ...

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 ...

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 ...

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 ...

COCKBAIN 1 has suggested an extension of the suture-line theory 2 of the origin and significance of pentamerism in the phylum Echinodermata, which depends primarily on the fact that all modern ...

WITH the completion of Prof. Koehler's account of the echinoderms from European seas, and with Dr. Mortensen's English work on those from British seas, the European, and particularly the British, ...

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 ...

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.
