A strange-looking marine worm has recently gained attention online, and once you see it, you’ll understand why.
This unusual creature, called Eulagisca gigantea, looks more like something from a sci-fi movie than a real animal found in Antarctica’s waters.

With its golden bristles and a mouth lined with sharp teeth, it has a unique appearance that makes it stand out. Even though this worm has been in the Southern Ocean for years, it is only now becoming widely recognized due to social media.
What Makes It Unique?
Eulagisca gigantea is about 8 inches long, similar to the size of a banana. One of its strangest features is its retractable throat, which extends outward when it eats. This exposes its sharp teeth, showing that it is not just an odd-looking creature but also a predator. It hunts or scavenges for smaller marine animals using this feature.

Its golden bristles might help it move, defend itself, or even serve another unknown purpose. Scientists still don’t fully understand this species because it has only been studied briefly since its discovery in 1939.
A Deep-Sea Mystery
Eulagisca gigantea belongs to the polychaete worm family, which includes thousands of different species. These worms are found in various ocean environments, from shallow waters to deep-sea hydrothermal vents.

There are over 8,000 known species of polychaete worms, but researchers believe many more are yet to be discovered. A 2016 study suggested that only half of all marine worm species have been identified so far, meaning there could be even stranger creatures hiding in the deep ocean.
A Viral Sensation
Recently, a Facebook post featuring a close-up of Eulagisca gigantea went viral. The image showed its metallic bristles and extended jaws, sparking both fascination and surprise among viewers.

Even though its appearance might seem unusual, creatures like Eulagisca gigantea play important roles in the ocean’s ecosystem. Studying them helps scientists learn more about life in the deep sea and the many mysteries that still remain unexplored.
