I just felt an intense flashback to high school presentations : "These are sea slugs. They live in the sea, because they are sea dwelling slugs. But these sea dwelling sea slugs don't only live in the sea, but they also live in oceans."
Yep. That pretty much sums up this channel.
Drink a shot every time you hear the word "sea" or "slug" and you're dead after ten seconds.
Reminded my of my english essays
The missile knows where it is.
I almost wish zefrank said something like this in his video on nudibranchs
0:45 when you’re trying to fill in the word count for your essay
Lmao, so true
Take a drink every time he said sea.
underated lmao
Perfect!! 😂🤣
That whole section honestly sounds like a shitpost
"...so if you see one, please leave it alone."
NOT GONNA BE A PROBLEM BUDDY
LOL
An ocean is a bigger version of a sea.
That's deep.
😂
🙂😎 “YEAAAAAAHHH”
Searched this
I laughed out loud 😞
Lol
Drink (responsibly) each time the word "sea" is mentioned. Perhaps we will save Tuvalu!
Challenge acce........THUD(passes out).
What about species?
Have a slug every time he...
Just drink
Umm maybe every other time he says "sea" for Americans playing the game. Getting an ambulance is expensive here
Had a beer when I started this video and read this comment, it didn't last long
ben: "they also live in oceans"
me: "in what now?"
ben: "the bigger versions of seas"
me: "ah cool, the more you know I guess"
The discussion of where they live seems to have been a contest about how many times they could say "sea slug"
How many seas would a sea slug slug, if a sea slug could slug seas?
I 'sea' what they did there..
Guys, quit joking around...time to get searious....
I requested you seas desist
Sea is for sea slug, that's good enough for me...
Are there any nudibranchs that aren't some sort of weirdly cute, alien looking, blobs of jelly?
It is indeed against the laws of a universe to have a nudibranch that isn't utterly fascinating in its alien beauty. It runs in their very being.
Perfect boneless lumps of squish, all of them.
Do they lay their eggs in a rose ribbon pattern like other nudies ?
@@Glory2Snowstar perfect blobs of thee most exquisite colors and patterns on such a teeny tiny canvas. Bucket wish...that I could have one of each, kept in a tank for a lifetime of joy.
Of course I would live in the ocean if I could.
How many times does he say sea
That’s what nudibranchs do. 😄
"Oceans, the bigger form of seas"
Yes, there are 4 oceans but dozens of seas.
Great animal of the week! 🤩
Melibe viridis are pretty cool! For me, their most unique attribute is their method of feeding. They have lost their radular teeth and have developed the oral veil into a large veil or "fish net" which they use to constantly scan the substrate as they crawl along. When touching a small crab or crustacean the edge of the veil is rapidly contracted, trapping the prey, which is then ingested.
love your content!
@@Dionaea_floridensis Thanks a lot! 🤗
What's your fav video so far?
If something on the sea floor looks like an alien, a demon and/or a dog's chew toy, it's probably a nudibranch.
The Sea Slug sleeps on the sea shore?
On the sea floor by the sea shore
Sadly, Sally is selling them at the southern sea shore.
This looks like a Precambrian creature
"Sea dwelling slugs known as sea slugs" made me laugh out loud
0:50 “Where in the sea is this sea slug seen?”
Another new animal I’ve never heard of!! Thanks Ben!
same
when I was a kid, there was a "toy", a chemical product really, called 'Slime'. If that product were to get flushed out to sea & suddenly become animate, This is probably the form it would take.
Ah, another episode of "Animals I'm glad don't live anywhere near me". Always enlightening, I love it.
Or: "Why I'm glad not to live in Australia"
0:48 oh? Does the seas slug sell seashells by the sea shore, because the sea slug slithers over the slimy sea floor?
I was looking for someone to do this comment for me!!🤣
The overall geometry of this sea slug reminds me the geometry of the fossil hallucigenia.
Great video, as always.
Nice. Agreed! I never woulda thought someone else was thinking the same thing as me. It’s kinda great being in a community of nerds 🤓
So the Cuttlefish of Cthulu from Gwar does exist.
Seeing this right after watching chapter 137 was wild
Was looking for this comment
It's kinda cute to be honest.
Yeah especially when you suck on its head
It’s head looks like something
@@ducklingwarrior No... You don't understand it.
@@ducklingwarrior I was thinking more the other direction
czcams.com/video/ARXqNc5DGXU/video.html
The ear of a mantis?
2 balls
Ben always make the weridest animals feel normal and i love it
This takes the term:”Butt head” to a much greater level.
0:58 😂 listening to you read that script saying “sea” and “slug” THAT many times I could hear you almost break and start laughing, how many takes did that involve?
I've seen images of this on Pinterest. However I never knew the species.
I don’t know why I assumed it was a type of siphonofore or jelly fish. I’m probably spelling that wrong.
This is my favorite biology based CZcams channel. I Look forward to a new video every week!
Something I found super fascinating about this animal is the glide symmetry of its "leg" lobes. I've never seen anything like this in modern Bilaterians (although I'm sure there are loads of more subtle examples, like patterning). The first and last pair have lobes that are directly opposite each other, but all of the rest are offset/alternating.
Really incredible, and it demonstrates some of the math involved in the ways that living things develop their bodies; maybe these "early legs" could eventually evolve to be more symmetrical? Charnia, a very early lifeform, also has this glide symmetry coupled with fractal growth, as did many of the Ediacaran biota.
That moment when you're trying to reach word count so you stress every opportunity to bring out "They are Sea Slugs where they live in the Seas."
It has an uncanny resemblance to a cambrian lobopod.
Convergent evolution is dope
Why do I love these things so much? They're adorable to me for some reason!
That is fascinating sea slug to learn about, great video Ben.
When this thing attaches to your spine and you become the founder
i like how these animals of the week are actually special.
Having this beaut be the star of some seed planet specevo project would be sick
This reminds me of the creature in Attack on Titan the one that attached itself on to ymir
I saw the thumbnail and title and seriously thought you were having me on. 😆😆😆
Loving these posts! Thank you👍
Corona drinking game in front of your screen: Take a shot every time he says "sea".
Slug buggy.
If i did that I would die
I have loved watching nature programs since childhood so I am very rarely surprised by a (to me) new animal. This one I had never heard about. Interesting.
It looks like a version of my dog's favorite kind of toy, but big enough to last longer than a week
3:00 that little shrimp is gorgeous
You pick the most amazing animals. Great work.
Wait wait WAIT... where do they live?
As an American i appreciate the conversion of measurement. Thanks brah
The living spine
That was interesting ill subscribe good video mate
Thus is so fascinating. Nature is an Artist.
What an alien-looking animal, like something from the Cambrian. I wondered if the “viridis” might refer to photosynthetic algae in its tissues giving it coloration, but my brief search indicated that though some other species in the genus do have them, this one does not. As you said, although it is a mollusk, it has lost its radula somewhere along the evolutionary line and converted to a “tentacled slimy hood of death” approach instead of boring scraping. More metal to be sure. Without that diagnostic radula and with its odd shape and without a larval stage to examine, If it had appeared in one of the Cambrian or Ordovician fossil sites preserving traces of soft-bodied tissues, I think it would have been unclassifiable.
New drinking game: Take a drink every time he says "sea"
Slug your buddy every time he says "slug".
0:50 - 1:15 pure gold
Thank you for teaching me about an animal I didn't know about.
Terrible challenge idea: Every time Ben says "Sea," take a shot.
What about 'see'?
@@GlitchedRed homophone. That counts too
That’s not Ben. It’s Thomas.
What cool creatures! Nature is truly fascinating.
This looks like the brain and spine with some ribs
Cool video, thanks. It should be pointed out that because they're hermaphrodites, that means sexual reproduction by definition (they form gametes with half the number of chromosomes). Asexual reproduction would be from fragmentation.
Take a drink every time he says "sea"
Asexual speciation in such a short time is interesting. They could have one common ancestor with a genetic mutation making it much more likely to survive and all the others of that brood dying off, as opposed to sexual evolution where the new genes are combined with older types. Either that or a simultaneous convergent evolution of all the members that swam through the canal.
3:15 Hermaphrodite reproduction is not asexual. It can happen between two individuals with a double or single sexual exchange and, if that option is not available, it can happen with only one individual self-fertilizing, which is generally less desirable.
Super interesting channel indeed!
👍☺
I dunno about them only being in tropical waters because they are quite common here along the coast of British Columbia. Here we call them nudibranches. And they are also in waters deeper than 10 m.
Thank you I had seen one in a documentary but for the life of me I couldn't find the criter!
The Burgess Shale called. It wants its organism back.
Thank you for the note of explaining why we should leave this alone when/if we see one ♥
New chalenge: take a shoot every time he says sea
Really weird and interesting creature. The head reminds me very much of a more solid creature I found on the beach once. It was greyish-purple and firm (completely opaque, as well), already deceased, looking in shape just like this creature's head (at least on the green-bodied form).
Anyway, enjoyed your presentation very much - thank you!
@Hua Cheng No, it was actually quite firm in shape, and had a rough surface. But the look was remarkably similar to this creature's head.
Cant eat my my nutrients? Good lets keep it that way nature.
the more I learn about sea slugs, the more I like them
this was a interesting video. I didn't know this sea creature existed.
I think you have gave-me a good idea for a D&D monster.
Ayy! My favorite Nudibranch
Damn, they got a mighty THICC head there
I see
This gave me zefrank vibes
The "sea shore sea dwellers known as sea slugs" part (or whatever you said) cracked me up lol.
very nice
They're adorable.
One shot for every "sea" and "slug"
She slugs
Sea slugs
Beneath the Javan Sea
Doug, you sound positively chipper today!
I haven't heard of this animal before!
They remind me of those gooey things that you can throw at the wall and it rols down.
The sea slug knows where it is because it knows it isn't on land
I had no idea these things existed. They look cute until you mentioned how they eat. Bad way to go!
“Ah, yes, time for a meal.”

^ >--~~~ “Schluuuuuurp”
Nudibranchs get my vote for one of the top five weirdest creatures right along with siphonophores and certain types of insects/arachnids.
0:45 Never thought I'd hear the word "sea" that many times in a single video
Would have liked to see video of this unusual movement
such a charming gelatinous blob!
Green Jelly Boi Has A Massive Glans.
octopus - highly developed 8 sided slug
Very cool video!.. Wished you could have included a video with these guys in action! :)
It's a slug in the shape of the Elder Sign, freaky.
always deserve attention!
Never heard of this strange animal befor. It's like a sea slug. Weird.
Omg I love himb 😍
Sea slug sells seashells by the seashore
"but I assure you it's from earth" good, I was convinced a soldier brought one back from space, but you've assured me otherwise.
