These Horrifying Sea Slugs Smell Like Watermelon Candies

The lion's mane nudibranch, also known as the hooded sea slug, is a unique marine creature with a distinctive oral hood used for hunting. Despite its small size, it captures prey like jellyfish and small fish by wrapping them in its hood. The nudibranch's most unusual feature is its watermelon scent, produced by terpenoids, which deters predators. Unlike other nudibranchs, it synthesizes this scent itself, as its prey does not produce it. This adaptation allows it to safely hunt and thrive in its environment.
