Creepy Sea Slug Discovered In Ocean

Meet Melibe viridis, one of the ocean’s strangest predators — a translucent, carnivorous sea slug with what looks like a gelatinous vacuum cleaner for a head. In this mesmerizing video, you’ll watch it unfurl its massive, hood-like mouth and suddenly snap it shut around unsuspecting prey, trapping tiny crustaceans in a split second. With its ghostly, see-through body and alien-like feeding style, this bizarre creature looks more sci-fi than sea life — proof that some of the wildest hunters on Earth glide silently beneath the waves.
