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.

These are really beautiful, but be careful! They eat the Portuguese man-of-war and keep its stingers in their own tentacles for defense. They can be quite painful!

I can't believe how beautiful all these little sea creatures are! We take for granted how amazing our Planet is! And we don't seem to have a problem destroying all the wonderful and amazing things God has giving us...

If I didn't know the name, and had to describe it, I would say, "Balloon Stinger Slug"

This why we as humans need to step up and start cleaning our mess that we have created in our oceans and continue to fight global warming against those who don’t seam to understand that everything harmful we do to our planet will eventually destroy it and all the beauty it currently has!

Leaf Slug (Elysia Chlorotica)
HalfeyHalphstein 10 years ago
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)
AshleyHauck 10 years ago
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/

You can tap on picture- click save - it will then be in with all photos - you can then edit as you wish, link to a printer via bluetooth and print in whatever size you wish (very easy if you are using iphone)

They’re called “rhinophores”, and they’re sensory organs. All sea slugs have them. Most of them are ribbed.

Hi!! I've been trying to internet-sleuth my way into finding the name for this sea slug and it's literally because of a REDDIT link (posted 6 days ago https://www.reddit.com/r/PicsOfUnusualSlugs/comments/162vygv/unidentified_nudibranch_photo_by_todd_aki/) that led me to a PINTEREST post in the comments, and I had to literally scroll and click on the closest looking slugs until I found this: https://www.pinterest.com/pin/6051780742360563/. PURE. DUMB. LUCK. On god there are actually more photos of this sea slug and THANK GOD. The photo I've attached is from here: https://the-three-p.com/gymnodoris-sp-51/ THE-FUCKIN...6f3665.jpg

Tottaly Tubular!!!! kinda like a jellyfish broski. Looks like a candle, probably smells delicious! 10/10 would eat, recommended. Foods 101, remember to subscribe to pewdiepie, and gamingwithkev. They are the best for breakfast. Omg my cookies are gone. This is a problem because they came in a tubular.

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.

Hi. They're hooded nudibranchs, Melibe leonina, a very unusual nudibranch which filters plankton from the water with venus fly trap like mouths.
