DEEP LOOK is a ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small.
The summer months bring low morning tides along the California coast, providing an opportunity to see one of the state’s most unusual inhabitants, sea slugs.
Also called nudibranchs, many of these relatives of snails are brightly colored and stand out among the seaweed and anemones living next to them in tidepools.
“Some of them are bright red, blue, yellow -- you name it,” said Terry Gosliner, senior curator of invertebrate zoology and geology at the California Academy of Sciences in San Francisco. “They're kind of designer slugs.”
But without a protective shell, big jaws or sharp claws, how do these squishy little creatures get away with such flamboyant colors in a habitat full of predators?
As it turns out, the nudibranchs’ colors serve as a warning to predators: These sea slugs are packing some very sophisticated defenses. And some aren’t above stealing weapons from their prey.
Gosliner and Brenna Green and Emily Otstott, graduate students at San Francisco State University, were out at dawn earlier this summer searching tidepools and floating docks around the Bay Area. They want to learn more about how these delicate little sea slugs survive and how changing ocean temperatures might threaten their futures.
Nudibranchs come in a staggering variety of shapes and sizes. Many accumulate toxic or bad-tasting chemicals from their prey, causing predators like fish and crabs to learn that the flashy colors mean the nudibranch wouldn’t make a good meal.
--- What are nudibranchs?
Nudibranchs are snails that lost their shell over evolutionary time. Since they don’t have a shell for protection, they have to use other ways to defend themselves like accumulating toxic chemicals in their flesh to make them taste bad to predators. Some species of nudibranchs eat relatives of jellyfish and accumulate the stingers within their bodies for defense.
--- Why do nudibranchs have such bright colors?
The bright colors serve as a signal to the nudibranch’s predators that they are not good to eat. If a fish or crab bites a nudibranch, it learns to associate the bad taste with the bright colors which tends to make them reluctant to bite a nudibranch with those colors in the future.
--- What does nudibranch mean?
The word nudibranch comes from Latin. It means naked gills. They got that name because some species of nudibranchs have an exposed ring of gills on their back that they use to breath.

This channel has rekindled my love for animals I had as a child, and all I gotta say is thank you.
This comment makes our day! You are welcome. We love making these episodes and want to make even more.
100% relatable. My first animal documentary is a show called eyewitness and deep look always able to gave me back my nostalgic childish curiousity. Love you, deep look.
Not saying i lost my love for animals, Deep Look took it to the next level! 11/10!
General Grevious same
My very first Deep Look video was the one about mosquitoes having 6 stingers in their mouth. And it was at that moment, I KNEW this channel will NEVER disappoint their audience as the quality of their content has always been something that Animal Planet, National Geography, Discovery Channel or any other worldwide wildlife documentary channel could not achieve.
From the videography to the animal of subject, Deep Look has never once failed to fascinate me!
❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
Those channel could achieve if they make short vids like Deep Look's.
I didn't know mosquitoes had mouth stingers?
Never disappoint huh?
You obviously haven't heard the commentary from their black widow video.
What's so disappointing about the commentary? Could you be more specific in your disappointment? I'm sure Deep Look would be eager to know.
The commentary for their black widow spider seems alright with me.
Nex Cyanic So you didn't catch the sexist undertones that the narrator was saying about males?
I can't they're too cute and like that purple one with a green like sea anemone on it's back is all out there like my heart has been blessed with these cute diva bbys
"Called sea slugs...they are basically snails without the protective shell."
...So they are slugs?
"Sea" slugs
Yep! there slugs
Slugs is just snails without shells.
so yes Sea Slugs are in fact sea snails without shells.
@@I_Dont_Believe_In_Salad Slugs and snails are completely different. But okay.
@@GrumbleGombol Your mother is Different.
But go off if you think Slugs and Snails are Different.
Never thought id think a slug was cute until today.
Yes that is true
Come to Santa Cruz, there's tons of cute little slugs here!
I always thought they were cute even the land ones, because of how innocent they are. Never judge a book by its cover
Am i the only one who want to touch a slug? Looks so squishy
TRASH look up the black sea slug, that thing could be a makeshift dumbbell
It would leave a burning sensation I think.
Not unless you want to get stung by Tony harpoons.

Yeah, I wouldn't go around doing that

Well these slugs should work for the phantom theafs
If I were to judge between 'Deep look' and 'Animal planet'
Deep look is the winner!!
Wow! We appreciate the kind words.
Honestly, no reason to pay for cable.

Sadly, most of these guys just decimate a reef tank, so they aren't good additions to the tank.. but there are herbivorous ones, like 'lettuce slugs', who are gorgeous, and help clean the tank!
New Message yea recently found out about vayssierea felis they kind of look like a nudi and flatworm mix but all they do is eat sporiond worms
I was thinking about that, I would love having that pink one or the one that looked like it was glowing blue.
Ima like bc of your name and your profile picture 😂😂😂😂

Dude I see u like everywhere

Nudibranch: yall hear smn
Nature is such an amazing joy to watch and learn about. Thank you!
Thanks María !
3:38 Lauren is a slug now..
These guys are the perfect analogy for bullies, no healthy defense against being hurt so they take things meant to hurt them and amplify it and project it onto others.. DEEP indeed
Yeah except these slugs are immune to the things that are supposed to hurt them, unlike real bullies who just pretend to be immune to it.
Y'all are too deep, i might find an oil rig and become rich
@@linnen_elm 👌😂 I gotchu with a alternative altering method of that oil to make it more environment friendly 💰 💰 💰
horrible analogy
Kinda, except they don't hurt the slug

Nudibranch not pronounced as branch but spelled exactly the same...
*_thanks english_*
deep love for deep look. (can i get a deep heart?)
D no love deep heart
Awww you got one!
Need money for deep throat..
Send nudibranchs... wait no
They Are Coming For You.........
Amazing sea slug clips. This is what you are looking for when you go diving, this slug is so small that you need experience, patient and a pair of sharp eyes to find it in the ocean and when you found it, its like finding a treasure.
I’m so happy you’re back! Also these sea slugs are absolutely adorable and that has to be a scientific fact!
I really wonder what type of animals are used to exist millions of years ago that we may never know
pipboy 4000 some seriously weird and wonderful things, considering how amazing some existing animals like these guys are!

amazing the variety of colors in sea slugs. even the sizes like the Black Sea slug. these things must’ve been around forever
Yep beautiful but dangerous
Imma just need to borrow this for the rest of my life thanks *never comes Back*

Btw, I saw a bunch of snails the other day, and learned 2 things: 1, a single snail can carry another snails of the same size, 2, they don't give a crap about falling or going underwater.
I missed you too Lauren! Love this show!
WHY ARE THEY SO ADORABLE
Your voice and narration is so mesmerising. Kinda cute and cuddly.
I like it too
i really like lauren's voice its satisfing and makes the video more complete
I've adored nudibranchs ever since first I saw one, at the Oregon Coast when I was about fourteen. I learned the basics of how they defend themselves, but this video made it graphically clear how they do it.
Good ol' KQED. Thanks for the great work from sunny Vienna, Scott
THESE SNAILS ARE SO PRETTY!!!!!!! 😍😍😍
0:26 it's like someone constantly blowing its hair out of its face.
The presentation of these videos are most underrated. She is excellent.
I just love how Lauren explain all these things
I love your videos. Incredible quality
My first Deep look video was that for the Daddy Longlegs and from this moment I LOOOOVE Deep Look! Seriosly, guys, you are 1000000 times better than national geographic and animal planet. I want more videos, PLEASE!!!
And can I get a heart, please?
they’re just so beautiful...
It just stole my heart
When you said "sea slug" I paused and remembered that that's my favorite type of creature.
THEY’RE SO ADORABLE I JUST WANNA SQUISH EM AAAAAAH
hand: "im dead"
Thank you for this information. To me, they are the most beautiful of sea creatures.
I fell in love with these creatures on Spring Break during a class field trip. I remember my chest hurting as a result of laying face down on a dock looking into the water at the encrusting creatures and these marvelous molluscs. Great presentation and graphics!
Thanks for interesting facts about this amazing creatures 👍😍❤
Their mouth is so cute 😂😂
I love their forms/colors
I freaking love the closeups!!!
wow DE really out did them selves with this Hydroid Prime trailer 01:00
Lol
“They’re basically snails but without the protective shells” so you mean... slugs?
Gorgeous lil critters and crafty too!
Loved this post. How amazing to even know all this about a tiny slug.
Someone remind me why we're looking for aliens when we have these cute alien looking thing under the sea o.o

Omg so pretty i wanna pet it
"Because their colors are actally a warning"
Um ok
I find it amazing that biologists / scientists are able to discover and find all this information out!!
These sea slugs are like snails without a shell.
If only we had a word for that...
I had no volume on so basically I watched cute slugs for four minutes.
Nice video keep up the good work also #notifocationsquad
#NotificationSquad
Gorgeous, interesting work, Lauren!
Thanks for this video. Recently I've been thinking of how animals collect poison from their food, for example puffer fish and poison dart frog. How does their digesting system work, how do they recognize and store the poison? But this sea slug is on another level - storing and releasing living nematocyst, that's amazing!
Imagine these being in Spongebob Squarepants.
They did, in an abysmal episode.
Ok so I've been pronouncing "nudabranch" wrong the WHOLE time. I used to say "noo-dah-BRANCH" BUT today i realize it's "noo-dah-BRANK"
Probably the most beautiful creatures on the planet.
Its such a beautiful creature. Their colours are beautiful.
