Upside-Down Catfish Doesn’t Care What You Think
There is nothing wrong with your television
set. Do not rotate your phone. You’re looking at the upside-down catfish. Seven different species live in the Nile and
Congo Basins of Central Africa. You might expect it to be anatomically different
from a regular catfish. But it’s exactly the same. So why does this catfish swim all topsy turvy? Maybe a better question is: How do fish stay
right-side up in the first place? Well, they have an internal air sac that they
inflate or empty to go up or down. It also keeps them upright. When they want to rise, they draw air from
their blood into this swim bladder, and release it to sink. This discus fish has swim-bladder disease. That’s why he’s having a hard time with
which way’s up. Our flipped catfish has a swim bladder too. And it CAN swim like your standard fish — if
it wants to. It turns its belly to the nearest surface
to probe with its sensory barbels — those catfish whiskers. So what’s the point of being upside-down
all the time? Well, near the surface of the water, fish
normally run into a problem called wave drag. Check out these regular catfish. It happens when their own movement disturbs
the water — making it harder to swim. But if a fish swims with like this, it doesn’t
shake up the water as much. That lets this upside-down-er graze without
getting so tired…and save its energy for evading predators. There’s also more oxygen in the water near
the surface, so it’s easier to breathe. And check out how this fish has a dark patch
on its stomach. Its name, “nigri – ventris,” means black
belly. That’s the reverse of most sea creatures. From above, that dark coloring camouflages
the fish, helping them blend in with the depths. It’s called countershading. So for these fish, life inverted… just feels
right. And we know they’re not the only ones who
work an unusual angle… Whether that’s tilted, sideways, or diagonal
Sometimes to get by, it doesn’t hurt to be a little different. Take another look at this anglerfish. Scientists at the Monterey Bay Aquarium Research
Institute filmed it way off the California coast, at 4000 feet. …Upside down. Surprising, these beauties aren’t usually
found alive. If you’re looking for even more perspectives,
try Above the Noise, from KQED and PBS Digital Studios, the series that cuts through the
hype of today‘s headlines with science. Thanks for watching – and subscribing – to

Hi, I'm Elliott, the producer of this episode. This time we're flipping the script a bit…And we do care what you think! 🙂 Please leave your comments and questions.
something smells fishy here
Well, you gotta do what you gotta do.
Thumbnail looks like a cow
I have this fish(Synodontis) with 12 cm length
The catfish is upsidedown swim dead
aka australian catfish
I thought the thumbnail was a giraffe for a second
At 1st when watching this in full screen i thought my phone orientation isnt correct. I rotate my phone twice
i do the same. if i swim too far in lakes. i swim upside town. i costs less stam
Looks like a cori
Like a blue sea slug, for it also swims upside down lol.

Feels just like my cat sometimes, it love to walk on its back.
Keep 'em in an aquarium furnished with spindly driftwood & you'll see how such atypical swimming behavior is a boon! I tell you, these catfish will hover around & beneath overhangs, perfectly hidden from danger.
I’m a perfectionist so this is annoying XD
I want one. Really.
Looks like a corydora.
Catfish simultaneously look like they possess infinite knowledge and like they just have the Mii theme playing in their heads non-stop
How is this video not a meme
They look broken….
I have a couple of plecostomi that swim upside down on the water's surface and at the bottom of the tank on the substrate. They even will roll a marimo moss ball on their bellies as they swim with their backs on the sand.
I have one of these in my tank
I have catfish and I turned them over and they won’t move instructions not clear
I have no idea why but I can't stop watching this video
I used to one of these babies as a pet! His name was Hay Hay. He was hilarious to watch swim around. Sadly he died from a horrible ICH outbreak from a new and infected fish.
I really liked the final message
I see so many different creatures ive never seen before on here. Absolutely love Deep Look.
Deep Look:Do Not Turn Your Phone Upside Down.
Me:-Turns Phone Upside down-
I just turn my phone upside down and voila! Normal catfish!
Why the black belly fish name had to be that. Or was it just me?
now i just need a fish that swims backwards
Plot twist: Fish swim bladder are carrot anatomys/anatomies
I want one as a pet now
ohh my it tricked me in the beginning
*i rotate my phone^^
I can respect that
"not tears left to cry"
Ok the video title is sad
2:25 woah i never knew we are bring colour into this, why you gotta be racist
He was just floating. Like how we do it on pool😅
I also dont care about what upside down catfish thinks
can’t find mine atm
THEY ALL LOOK THE SAME UPSIDE DOWN TO ME. BUT THEN AGAIN SO DO WOMEN !
Just got catfished, and then I see this in recommendation.
They look cute
Wow I really thought my phone was crashing😂
👍❤
my brain turn upside down when watch this catfish
Trivia: In some country, catfish is a delicacy. In some other country, catfish are use to eat himan feses
I watch upside down
australian catfish*
It might care what I think, given that I have a particular fondness for eating catfish. Fried catfish+french fries+hush puppies+cole slaw=yummy! Add to that some weissbier to wash it down and things are wonderful.
I heard somewhere that floating fish food can actually contribute to swim bladder disease in aquarium fish, though I'm not exactly sure how that works.
Scientists:we need a new unique creature.
Scientists:U—…up..UPSIDEDOWN CATFISHES!!
I click on this video because the upside-down catfish don't care about what I think, like every cat.
This is cool.
Was this video made in Australia?
When you're playing Minecraft and name your pet 'dinnerbone'
This is no fish, its disguised bread covered in butter. Always wrong side down…
You got catfished.
Doing things upside down doesn't work with us. We aren't made in a buoyant medium but our blood flows down into our feet which are made to handle the higher pressure being on the bottom so we don't feel it.
We can be different but it's being wrong that we should never be.
I thought the thumbnail was a giraffe head or something
No aquatic creature cares what we think.
Gangster fish!
#catsfishMatters
I think the inverted counter shading is so freaking cool. Nature is so smart.
my goldfish is upside down too i wonder why?
olvive garden
Do not rotate your phone
Me: rotates the phone 180°
All Australian animals are upside down except for that fish
Lily…pads.
Upsid-down and chill..
Video: Don't rotate your phone.
Me: Rotates Phone
i have a few upside down fish in my tank, they don’t move but its there
Thumbnail looks like a pelican.
Imagine if somehow ALL fish did this and there was just one poor species that was stuck "right side up"
So these catfish are smarter than the usual Joe?
who used a dinnebone nametag
Who else still checked the fish by turning your device upside down
The Australia fish
the intro music of these videos sound like the music from resident evil the biohazard the video game
But what if I have a flip phone?
I want that catfish fried
The dialogue at the start reminded me of the show the outer limits.
Another fish: what kind of weird fish are you
Catfish: don't care
I have these, sometimes I think they are dead untill i try to touch them
But what about fish in Australia?
These fish are adorable!
Who else thought it looked like a giraffe
Maybe we're upside down leave it alone
So my pet is as lazy as me!!!! Universe!!!
