50-80% of all life on Earth is found in the ocean. That makes sense considering the ocean covers 99% of Earth’s surface. The crazy thing is, scientists have only explored less than 10% of the entire ocean.
Despite how little of the ocean’s mass we’ve discovered thus far, what we have found is pretty incredible. Take these oddly adorable sea slugs for example.
Many of the slugs featured in this post are really snails that have lost their shells and gained new characteristics over the years through the process known as evolution. No matter how they originated, all of the sea slugs on this list are either Aliens from another Planet or some of nature’s most uniqely beautiful creations.

12. Lettuce Sea Slug (Elysia Crispata)
“Lettuce Sea Slug With a name like E. crispata and an appearance like curly salad greens, the Lettuce Sea Slug could almost find itself at home in your crisper drawer. It’s not even closely related to nudibranchs. It belongs to a different category of slug entirely, known as ‘sap-sucking slugs,’ named for its propensity for slurping the juicy bits out of the algae it eats. It even retains chloroplasts in its tissues that provide it with sugars.”
