Paleontological research has revealed a remarkably small, three-eyed predator – dubbed the “sea moth” – that lived 506 million years ago. Unearthed through the analysis of over fifty fossils, the creature measured just 0.6 to 2.4 inches long and was named *Mosura fentoni* in honor of the Japanese “kaiju” Mothra, reflecting its moth-like appearance. The discovery, highlighted by CNN and shared by a Slashdot reader, offers a fascinating glimpse into ancient marine life.
