A strange and mesmerizing marine worm has recently gone viral online, and once you see it, you’ll understand why
This bizarre creature, Eulagisca gigantea, looks like something out of a sci-fi horror movie rather than a real animal from the icy waters of Antarctica. With its shimmering golden bristles and gaping, tooth-lined mouth, it appears more like a terrifying holiday ornament than a marine worm. Yet this strange species has lived quietly in the Southern Ocean for decades, only recently gaining viral fame thanks to social media.
Growing up to eight inches long, this worm has a retractable throat that extends outward to reveal sharp teeth—perfect for catching smaller marine creatures. Its golden bristles likely help it swim, crawl, or defend itself. Scientists believe Eulagisca gigantea is a type of polychaete worm, a diverse group with over 8,000 known species.
A viral Facebook post showing its metallic glow and fearsome jaws left viewers both fascinated and horrified. Despite its monstrous appearance, this deep-sea predator plays an important role in marine ecosystems and reminds us just how strange—and spectacular—life beneath the ocean’s surface can be.
