51 Sea Slugs That Prove Aliens Already Live On Planet Earth
Seeing how much you liked our "Sea Bunny" and "Sea Sheep" post, we decided to dive deeper to see what else is hidden beneath the sea. We were pleasantly surprised to find that the ocean is full cute slugs!
Most of these “slugs” are actually snails that have lost their shells and gained new characteristics through evolution. For example, sacoglossans are sometimes called “solar-powered sea slugs” because they use chloroplasts from the algae they eat in their own tissue.
Vote for your favorite, or if you happen to be a deep-sea diver, post your own pictures below!

Leaf Slug (Elysia Chlorotica)
This sea slug is capable of producing its own food from photosynthesis. The green pigment inside its body is really chlorophyll, the same pigment found in green plants used to absorb the light energy for photosynthesis. However this sea slug did not make the chlorophyll itself, instead it was obtained from the algae they consumed at earlier stage of their life.
Lettuce Sea Slug (Elysia Crispata)
Thanks for picking up my photo of E. crispata! Here's an excerpt from my blog about it: 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 looks like a nudibranch, and those who know me know I love nudibranchs, but it isn't. 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. AND it's frilly. Sweet. - See more at: http://www.ashleyhauck.com/blog/curacao-slugs-snails-spirobranchs/

I love these things. They have terrifying giant mouth-hoods, and yet they still have those little bunny-ear-like rhinophores on their heads. They’re like nightmare bunnies. Also, they release watermelon-scented defensive toxins.
