On the ocean floor, many animals rely not on speed, but on defense. Echinoderms include sea stars, sea urchins, and sea cucumbers, all sharing unusual body structures and survival strategies. Some are ...

The discoveries made in the Nankai Trough and the Shichiyo Seamount Chain remind us how little of our ocean has truly been explored.” ...

Echinoderms are a phylum of exclusively marine deuterostome invertebrates characterized by pentaradial symmetry in adults, a calcareous endoskeleton composed of ossicles, and a unique water vascular ...

It used to be thought that sea urchins only had a primitive nervous system, but new research has found that they are far more complex than that. The entire body of a sea urchin is what researchers are ...

Sea urchins, the spiny marine animals, may appear simple, but new research shows their bodies are almost entirely made of "head" and contain a highly complex nervous system that works like an ...

Sea urchins have a body that is entirely made up of "head"—with a surprisingly complex central nervous system that functions, in essence, like an "all-body brain." This is the conclusion of an ...

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 ...

Starfish are some of the most recognisable animals in the world. But their simple appearance belies an evolutionary mystery - how did these animals evolve such an unusual shape? A new fossil discovery ...

The film explores the fascinating world of echinoderms, focusing on sea stars and their relatives, such as sea urchins and sand dollars. It describes their unique body structures, including radial ...

How does rapid burial work? New insights from experiments with echinoderms. Burial is a critical factor in the preservation of most fossils, keeping scavengers away and preventing the disarticulation ...

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 ...
