Paleontologists have discovered a new species of radiodont, a three-eyed predator nicknamed the "sea moth," from 506 million years ago. Named *Mosura fentoni*, this creature, about the size of a finger, possessed unique features including a segmented abdomen with gills and unusual claws. Its discovery, based on over 60 fossils from British Columbia's Burgess Shale, sheds light on the evolution of arthropods and the diversity of early marine ecosystems. The well-preserved fossils even reveal traces of the creature's nervous, digestive, and circulatory systems, offering unprecedented insight into Cambrian life.
