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

Here, we tested these classical hypotheses by examining gene expression in the asteroid (sea star) Patiria miniata (Extended Data Fig. 1a, b), using a statistical approach based on spatial ...

The Dmrt (Doublesex-mab3-related transcription factor) gene family is a class of crucial transcription factors characterized by one or several conserved DM (Doublesex/Mab-3) domains. Dmrt family genes ...

(Phys.org)—A team of researchers from the U.K. and the U.S. has identified the remains of a 430-million-year-old extinct echinoderm found in a fossil bed in Herefordshire, England. In their paper ...
