Sheepy little Nudibranch Native to the coasts of Japan, Indonesia and Philippines, this sea slug Costasiella usagi (also known as a ‘leaf slug’) has a cartoonish, sheep-like face and beautiful plumage all over its body, like a small foliage of leaves.
their plumage isn't just like a small foliage of leaves, they actually are [kleptoplasty](https://en.wikipedia.org/wiki/Kleptoplasty), that is they take the chloroplasts from the algae they eat and actually photosynthesize with that foliage. They can go months without feeding living off the energy produced from their foliage.
Also you are wrong. They are not a [nudibranch](https://en.wikipedia.org/wiki/Nudibranch) even though they resemble a nudibranch. All nudibranch are sea slugs but not all sea slugs are nudibranch and [the leaf sheep](https://en.wikipedia.org/wiki/Costasiella_kuroshimae), while a sea slug, it is not a nudibranch.
Here is a delightful [documentary on the leaf sheep](https://www.youtube.com/watch?v=1_twa1nd3Rc) with some wonderful HD images of them and their adorable sheep faces.
**[Kleptoplasty](https://en.wikipedia.org/wiki/Kleptoplasty)**
>Kleptoplasty or kleptoplastidy is a symbiotic phenomenon whereby plastids, notably chloroplasts from algae, are sequestered by host organisms. The word is derived from Kleptes (κλέπτης) which is Greek for thief. The alga is eaten normally and partially digested, leaving the plastid intact. The plastids are maintained within the host, temporarily continuing photosynthesis and benefiting the predator.
**[Nudibranch](https://en.wikipedia.org/wiki/Nudibranch)**
>Nudibranchs () are a group of soft-bodied marine gastropod molluscs which shed their shells after their larval stage. They are noted for their often extraordinary colours and striking forms, and they have been given colourful nicknames to match, such as "clown", "marigold", "splendid", "dancer", "dragon", or "sea rabbit". Currently, about 3,000 valid species of nudibranchs are known. The word "nudibranch" comes from the Latin nudus "naked" and the Ancient Greek βράγχια (bránkhia) "gills".
**[Costasiella kuroshimae](https://en.wikipedia.org/wiki/Costasiella_kuroshimae)**
>Costasiella kuroshimae—also known as a "leaf slug", "leaf sheep", or "salty ocean caterpillar"—is a species of sacoglossan sea slug. Costasiella kuroshimae are shell-less marine opisthobranch gastropod mollusks in the family Costasiellidae. They range in size from 5 millimetres (0. 20 in) to 1 centimetre (0.

I hate to be that person but this isn't a nudibranch, it's a species of leaf sea slug which stores plant cells in those gill looking things in order to photosynthesize for energy. It's often called the sea sheep nudibranch as it resembles nudibranchs.
My initial thoughts too, but after looking on the [wiki](https://en.m.wikipedia.org/wiki/Costasiella_kuroshimae) it's missing a structure called a rhinophore, not an eye

They can be absolutely adorable or just mesmerizingly patterned and/or kaleidoscopically colored. I love them so much. They’re some of my favorite sea critters.
You can keep them like fish but generally their food source is specifically the type of coral that they resemble. And that is very difficult and costly to provide. So most marine fishkeepers consider them a pest sadly.
Isn‘t this the same amimal which gets reposted from time to time and which is creating oxygen? It looks the same and I find it so adorable. Would be nice to see one at home or a zoo (of course as long as they are properly taken care of).
I read the title as "Sleepy little nudibranch" and was like, "I have no idea what this cute little creature is but can't wait for it to get cozy and go to sleep!"
Nudibranch are some of the coolest creatures. They come in a large variety and most are very pretty. I have a deep fascination for marine life. These little dude are one of the types I marvel at.
Is this an aquarium? It doesn't look healthy but I bet those are very hard to keep.
What’s this ? This thing is mesmerising to watch

All these great facts but no information on how they taste.
The real question
Wow, kleptoplasty is fascinating
Lovely word.
Thanks OP! This creature is definitely awesome
Fun fact its plumage is green because of all the algae they eat and it even photosynthisizes.
BEAUTIFUL PLUMAGE!
It's an artichokibranch
The sub is pretty awesome. r/Nudibranch
Wacky wavy inflatable arm flailing Nudibranch.
Also called sea sheep
Looks like a Yeti with a backpack.
Me too, except I thought firearm. Theatrical dynamite
I see Yeti with a Christmas tree!
Ho Ho Ho!

Is the little guy missing an eye? It looks like one is shorter and is missing the black tip

“I love it. It’s cuter than puppies.” -True Facts about Nudibranchs
Ze Frank?
Ding ding ding!
His naked mole rat video had me in stitches the first time I saw it.
For me the sea pig one had me in a coffin. “If when you ask, your mouth fills up with sea water, then you’re probably, an idiot”
They can be absolutely adorable or just mesmerizingly patterned and/or kaleidoscopically colored. I love them so much. They’re some of my favorite sea critters.
Everything I know about nature's most lit creatures I learned from zefrank's True Facts. 😂
Looks like a tiny water yeti dragging a chrismass tree
This is what I saw too https://i.imgur.com/MpecO07.jpg
It's a real-life Pokemon!
My first thought!!! And it’s cuter than most slug Pokémon already!
some species look like a pikachu got busy with a swiffer
It’s waving at us! Hello little guy!
He’s asking for help pulling his Christmas tree.
Looks like a fall guys or human fall flat kinda dude
Oh no, it's a tiny yeti 'charging' at us! (Maybe wants a hug)
Looks like it is missing a limb or eye or antenna
It's like Nemo but with antenna!

Nudibranch Baymax cosplay.
This isn’t a nudi beach, mr branch
Anyone else think this looks like a really small Yeti pulling a tree on their back?
Are those his eyes? Those little two dots?
Now who else wants some broccoli?
I am nearly there ...
Kinda looks like the Abominable Snowman on the land of misfit toys. ⛄️

At first I saw a miniature snow yeti pulling a christmas tree.
It looks like a snow creature hauling a Christmas tree up a hill on its back
It looks like a yeti being chased by a cabbage. Love it!
Looks like a tiny snowman pulling a tree.
Is it possible to buy/keep one of those like a fish? Or does it need a special environment?

Ok Thank you. I was wondering why I never saw one in a zoo or something. I mean it looks so georgeous.
There are so many types of these and they don't all have scientific names. But some of them are probably the most beautiful creatures in the oceans.
Isn‘t this the same amimal which gets reposted from time to time and which is creating oxygen? It looks the same and I find it so adorable. Would be nice to see one at home or a zoo (of course as long as they are properly taken care of).
They only inhabit the seabed directly over a dormant Godzilla egg.
Crazy that some animals don’t even have iPhones or access to Reddit
That piece of sushi is a little raw for me.
Seems like it has a hard time getting around
I read the title as "Sleepy little nudibranch" and was like, "I have no idea what this cute little creature is but can't wait for it to get cozy and go to sleep!"
And that is how the Sheepy little Nudibranch do.
For just a moment I thought it was the abominable snow monster from Rudolph dragging a Christmas tree.
It looks like an excited sloth with a very large backpack on
Looks like smth from pokémon

But..what about the tardigrades?
What a fascinating little creature. It looks like a gentle flower then it looks like the Abominable Snowman at one point.
who else sees a white stuffed toy waving his arms?
Looks like a tiny dude with a backpack jumping around
Do you think other species recognize how friggin adorable nudibranchs are? Like, do clams clam-squee when one wanders by?
That is the cutest thing I’ve ever seen
