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

What do barnacles, Dungeness crabs, and giant sea spiders have in common? How about snails with iron shells, vampire squid, and “pill bugs” the size of cats?

Echinoderms are an important intermediate group in animal evolution that combines the geometric beauty of five-fold radial symmetry with a high degree of mobility in the ocean. Five-fold radial ...

Sea urchins are globe-shaped creatures that live on the ocean floor. Many beachgoers have had the misfortune to feel a sting from their spines, but how much do you know about the lives of these ...

One of the wildest wonders of nature is the ability of some animals to reproduce by splitting in half. There is still so much we don’t know about this process. So the discovery of a ...

Marine biologist Dr. Dave Pawson has embarked on over 100 dives to the ocean floor to unravel the mysteries of elusive invertebrates like sea cucumbers and brittle stars Emma Saaty There are few ...

Carnegie Mellon researchers, collaborating with Spanish and Polish paleontologists, have created a soft robotic model of the pleurocystitid, an ancient echinoderm, to explore evolutionary biomechanics ...

For the first time, a trilobite fossil has been found with preserved gut contents, and an analysis of the specimen suggests the iconic ancient animal had a voracious and unfussy appetite. “Most fossil ...

Despite their name, sea cucumbers aren’t fruits or vegetables. They’re marine animals. These ancient creatures have been moving slowly across the sea floor for millions of years, recycling ocean waste ...

This important study combines single cell and single nucleus transcriptomics to two echinoderm embryos to identify embryonic cell types and assess cell type evolutionary novelties. The paper provides ...
