The ocean is a wild habitat where any keen beachgoer could spy a myriad of marine life that comes covered in shells or swims ...

Researchers Trace Evolutionary Trajectory of Starfish's Unique Symmetry Through a 500 Million-Year-Old Fossil The star shape of the starfish (five arms) is intriguing to many marine aficionados. But ...

Learn how starfish got their shape after a complicated evolutionary process, starting with an ancestor that lived 500 million years ago.

What we then see through the fossil record is a transition from bilateral symmetry, to asymmetry, then threefold symmetry, before we arrive at the pentaradial symmetry that defines all living ...

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 ...

Discovery of 500-million-year-old fossil Atlascystis acantha shows how modern-day five-armed starfish and relatives evolved from an ancestor with two ‘arms’ A 500-million-year-old fossil from Morocco, ...

In contrast, radial symmetry — seen in organisms like sea urchins — distributes body structures equally all around. Interestingly, many internal organs of a rat tail still retain radial symmetry.

Starfish are star-shaped marine invertebrates that are found in oceans all around the world, from shallow coastal waters to some of the deepest depths possible.
