🎥 Présentation de Nebula et des poissons-crapaud
Le script commence par une présentation du service de streaming sponsorisé, Nebula, qui a récemment été redesséiné avec de nouvelles catégories de contenu et des productions originales. L'animateur exprime son enthousiasme pour parler des poissons-crapaud, des créatures comiques et inhabituelles, faisant partie de l'ordre des Lophiiformes et de la famille des Antennariidae. Les poissons-crapaud sont répartis dans le monde entier, à l'exception du poisson-crapaud de Sargasse qui vit dans les algues de Sargasse. L'animateur mentionne également son affection pour les noms scientifiques répétitifs et le fait que les poissons-crapaud ont existé il y a environ 53 millions d'années.
🐡 Caractéristiques et mode de vie des poissons-crapaud
Les poissons-crapaud sont décrits comme ayant un corps globuleux et non fusiforme, ce qui leur donne une apparence peu ordinaire pour un poisson. Ils sont plutôt maladroits nageurs, utilisant une méthode de propulsion appelée 'jetting'. Leur morphologie est également inhabituelle avec des nageoires pectorales et pelvicaires qui ressemblent à des pattes, leur permettant de se déplacer en marchant. Les poissons-crapaud sont capables de se fondre dans leur environnement grâce à leur camouflage, ce qui est particulièrement efficace pour échapper aux prédateurs. Cependant, ils utilisent également une stratégie d'aggressive resemblance pour attirer leur proie en imitant des éléments de l'environnement qui attirent les animaux qu'ils chassent.
🎣 Leur technique de prédation et leur apparence variable
Les poissons-crapaud sont des prédateurs efficacés qui utilisent une combinaison de camouflage, d'aggressive resemblance et d'un leurre pour attirer leur proie. Leur leurre, qui se trouve en haut de leur tête, est unique pour chaque espèce et peut ressembler à divers types de petits animaux ou d'algues. Ils peuvent également changer de couleur pour s'adapter à leur environnement. Les poissons-crapaud sont des prédateurs qui attendent patiemment et utilisent leur leurre pour attirer la proie, qu'ils attrapent avec une rapidité remarquable grâce à leur grande bouche qui peut s'ouvrir très vite.
🤯 Comment les poissons-crapaud attrapent et digèrent leur proie
Le processus de capture de la proie par les poissons-crapaud est décrit en trois phases : la phase de pré-attaque, la phase d'attaque et la phase de manipulation de la proie. Durant la phase d'attaque, les poissons-crapaud peuvent ouvrir leur bouche jusqu'à 12 fois sa taille initiale et avaler leur proie en seulement 7 millisecondes, une capacité sans précédent chez les poissons. Après avoir attrapé leur proie, ils l'emmaillotent avec leurs dents pharyngées et la déglutissent. Cette méthode de prédation est à la fois impressionnante et terrifiante, mettant en évidence la nature redoute des poissons-crapaud malgré leur apparence comique.

Transcripts
This video is sponsored by my streaming service, Nebula.
I’m sure you’ve all heard the usual spiel about Nebula before, that we’re an
independent platform owned by talented creators like Chubby Emu, Tier Zoo, and...
me! But you might not have heard about how Nebula has gotten a whole
new redesign, our biggest update ever!
All of our content is now broken up into Categories: News, Culture, Science,
History, Podcasts, and Classes, and each category will be like its own
mini service, which will make it easier for you to find content from both
new creators and existing favorites.
We’re also investing in more big-concept, high-octane Nebula Originals, which are
videos found only on Nebula, divided into two categories: Fact and Fiction.
And we got some really great stuff coming up, like Bobby Broccoli’s new
documentary called The Baltimore Scandal.
We’re spending more on Original content than ever before, developing creator-built
projects you can’t see anywhere else.
And we are funding these endeavors through our Lifetime memberships!
You pay $300 once, and then, you get access to Nebula forever.
Period.
No tricks or gimmicks!
If somehow, both you and Nebula last until the heat death of the universe, you’d
still get access to all our great content.
Otherwise, if you sign up using my link at nebula.tv/theoctopuslady or use the
link below, you can support me directly and get Nebula for 40% off annual
plans, or as little as $2.50 a month.
So thanks again to Nebula for the sponsorship, and now onto the video…
Hi, I’m the Octopus Lady, you’re watching Alien Ocean, and let’s
talk about frogfish today, shall we?
So frogfish are, and this is the
scientifically accurate way to describe them,
EXTREMELY goofy looking.
And I’m so excited to talk about them today, because, as I’ve mentioned briefly
in a couple other videos, I am an absolute sucker for goofy looking fish, and oh man.
Oh man.
Oh man!
Do these fish get goofy lookin’!
But I’m getting ahead of myself.
We gotta do the usual stuff first.
Frogfish are part of the order Lophiiformes, meaning they are related
to another very interesting group of fish, but I’ll talk about that later,
and more specifically, they make up the family
An…ten…aur..ree…uh…dye.
Nailed it?
They’re found all over the world, mostly along the coasts and in waters
around 20 degrees Celsius, with the exception of Histrio histrio, or the
Sargassum frogfish, which is found floating out in the middle of the ocean
on big ol’ mats of sargassum algae.
By the way, another thing I’m an absolute sucker for is when an
organism has the same name, like, twice, for its scientific name?
Like Histrio histrio, Mola mola, and…
this is apparently pronounced
Boh-ops boh-ops, but I’m never gonna pronounce it like that.
No one should EVER pronounce it like that.
The oldest fossil we’ve found of a frogfish dates back to about 53 million
years ago, which means they might’ve first showed up around the same time
as moray eels and sacoglossan slugs.
And I don’t really know where to put them on my fossil timeline thing,
so I guess I’ll just stick ‘em…
here.
Gah, this looks terrible.
Now with all that out of the way, let’s talk about how goofy-lookin’ frogfish are.
Cuz they’re goofy-lookin’-ness kinda makes it seem like they’re bad at being fish.
See, first off, most fish are sort of, y’know, sleek.
They’re not all built like swordfish, of course, but most fish basically
have a fusiform body plan, so tapered at the ends and wider in the middle.
This is a good body plan to have if you need to move through a relatively
dense medium like water, but frogfish do not subscribe to this body plan.
I have seen them be described repeatedly as “globose” which
basically just means spherical.
They’re a spherical fish!
They’re like Boggy the Froggy from Fantasy High, except they’re Boggy the Frog…
fish.
If you understand that reference, GET IN THE COMMENTS.
As a result of this body plan, frogfish aren’t very good at swimming.
I mean, they can do it, but it looks awkward.
And sometimes they don’t even swim, really?
They jet, which is when they take in mouthfuls of water and eject it out their
gills, and that propels them forward.
Which is not – that’s not how swimming works!
Although, I gotta admit, I’m kinda genuinely impressed with how well this
mode of transport seems to work for them, but, still, you’re not supposed
to use your mouth to swim, my guy.
You’re supposed to use your fins!
But speaking of.
Their fins are weird!
So here’s a typical fish, which has all different kinds of fins,
but the ones we’re gonna focus on are the pectoral and pelvic fins.
As you can see, the pectoral fins are on the sides of the fish and can stick
out from them at a 90 degree angle, and the pelvic fins are basically
directly underneath the pectoral ones.
And they’re both, kinda, y’know, fin-shaped.
Meanwhile, you see this leg-looking thing sticking out the side of this frogfish?
Yeah, that’s their pectoral fin.
Which, by the way, ends in, like, a hand?
Like it kinda looks like they have a hand at the end of their pectoral fins.
And I realize that most people will probably think that’s kind of unsettling,
but I think it’s kind of cute!
They can even grasp things in their…fins, I guess!
I dunno, that makes me just want to hold hands with a frogfish.
Like I just think that would be really cute!
And as for their pelvic fins, hold on, I got the perfect photo for this --
BAM! Look at her!
Look at that pose!
It’s fresh, it’s fabulous, it’s fierce!
It’s saying, “I’m here, I’m weird, and I’m a sphere!” [giggles]
So DUMB.
But yeah, these things?
That are not directly underneath their pectoral fins?
And kinda look like…
feet, I guess?
Those are their pelvic fins.
Frogfish just unsubscribed HARD from the typical fish body plan, didn’t they?
And the reason why frogfish have fins like this is because they walk everywhere.
That’s the primary way that they move around.
Although, they’re not the greatest at that either.
Like, look at this guy, he looks like he’s stumbling out of a
frat house on a Sunday morning.
He can barely keep himself upright.
Ugh, he’s perfect, you’re perfect, my darling.
Never change!
You hear me, Evolution?
You do not let frogfish get better at walking, you understand?
You leave them alone!
You can often find frogfish walking around on rocks, coral reefs,
and sandy bottomed substrates.
Or at least, in theory, you can see them walking around, except they’re,
like, REALLY good at blending in with their surrounding environment.
And they’re capable of doing this in multiple different ways.
“Multiple different ways?” some of you might be saying right now.
“Isn’t there only one way you can blend in with your surrounding environment,
and that’s through camouflage?”
Which, yes, but also, no.
OK, so we’re gonna get a little pedantic with the definition
of that word in this video.
So camouflaging is not just when an animal imitates their background
or the substrate they’re on.
They are specifically imitating background or substrate that is uninteresting.
They’re trying to look uninteresting to their predators or their prey or both.
Camouflaging can also be called passive resemblance or passive mimicry.
I think.
I think you can use those terms interchangeably.
And frogfish do camouflage, they often look like rocks covered in algae or
like, some sort of sponge and predators typically are not interested in rocks
or sponges, so this is an effective way for frogfish to hide from them.
However, it’s a different story when it comes to their prey.
See, lots of animals on coral reefs, including animals that frogfish like
to eat, are constantly looking for shelter, either as a place to rest, or
hide from a predator, or lay their eggs.
But there is a housing crisis on coral reefs.
Some studies suggest that at any given moment, 100% of the
space on a reef is occupied.
Even the smallest patches of substrate got someone chilling there.
Many of these animals like to take shelter up against things like, idk,
sponges, or rocks covered in algae.
So if you live on a coral reef, and you find an unoccupied bit
of space, you jump on that.
And frogfish are pros at not just looking like a good place to take shelter, but
also appearing completely unoccupied.
How?
We’ll get to that in a second.
But this is an example of what’s called aggressive resemblance.
It’s when you are hiding from others, but in a way that makes you look
interesting, as opposed to camouflage or passive resemblance, which is when
you’re hiding from others, in a way that makes you look uninteresting.
And to certain kinds of prey, some of the hirsutier-looking
frogfish can appear extra enticing.
Is that even a word?
I don’t care.
It’s believed that these hairy boys are trying to look like they’re
covered in a specific kind of algae, filamentous algae, which is an algae
that is very hard to come by on healthy coral reefs, in part because it’s the
favorite food of many herbivorous fish.
So how can frogfish, who live in an environment where potentially
100% of all available space has got something living there,
make themselves look forever unoccupied?
Well, it’s really simple, they eat everything.
EVERYTHING.
Anything that gets close enough to them, they’ll eat it.
They sometimes even eat things that are bigger than they are.
Or try to, anyway.
Dude.
Give it up.
It’s not gonna happen.
Here’s a better example.
You see this?
This is an x-ray of a frogfish, and you see that?
That’s a whole ‘nother fish inside its stomach, which, according to the caption
of this image, had a body length that was greater than that of the frogfish.
They’re top-tier predators, is what I’m sayin’.
They successfully capture prey about 91% of the time.
And they don’t do it like many other predators.
Because in case you didn’t know, many other predators are…
chumps! They have to expend
so much energy every time they want to eat something, because
THEY have to chase after their prey.
And all that effort might be for nothing, if their prey manages to escape.
But frogfish are, like, the textbook definition of “work smarter, not harder,”
because they do the exact opposite.
They’re what’s called a sit-and-wait predator, because with their camouflage
and aggressive resemblance, they can just sit and wait for their food to show up.
And they don’t even always have to wait, really, because they have
a third weapon in their arsenal.
Their lure.
Frogfish have a lure that comes out of the top of their head and dangles in front
of their face, like, y’know, a fishing lure, which they use to attract prey.
And this might sound familiar, because yes, frogfish are, in fact, related to
the more famous, or perhaps infamous, deep sea anglerfish, who also have a lure.
But I’m not gonna talk about them here, cuz they’re gonna get their own
video at some point in the future.
The frogfish’s lure is made up of two parts, the spine, and the bait, or esca.
And each species of frogfish has it’s own unique esca, which is basically the only
way we can tell different species apart.
For a long time, we didn’t actually know exactly how many species of
frogfish there were, cuz they can change the color of their skin.
Did I mention that yet?
Yeah, that’s another thing that they can do, is change the color of their skin,
into all different kinds of colors.
Yellow and black and white and orange and...
whatever is going on here.
Like, these are all the same species of frogfish, which is wild and explains
why we didn’t know for a long time exactly how many there actually were.
Cuz, tbh, I wouldn’t have thought these were all the same species.
And presumably, the reason frogfish change the color of their skin is so they can
adapt to new areas they wander into.
If a frogfish is in an area with a lot of yellow sponges, and then
stumbles drunkenly into an area with a lot of pink rocks, they’ll change
the color of their skin accordingly.
Anyway!
Lures.
Spines.
Escae.
Escae is the plural form of esca.
They’re unique to each species of frogfish.
Some just look like…fleshy balls? And some look much, much, much more elaborate.
Which brings us to the topic of aggressive mimicry.
Aggressive mimicry is when a predator mimics another animal in a way that
is appealing to that predator’s prey.
This is different from aggressive *resemblance,* because aggressive
*mimicry* requires that the predator mimic a specific animal in some way.
So not just look like it, but behave like it or move like it
or something along those lines.
Aggressive *resemblance* is more like when an animal imitates usually
non-living things in their environment.
I think.
It was really confusing to try to figure out the differences between aggressive
mimicry and aggressive resemblance and passive resemblance and passive mimicry
and protective mimicry and camouflage.
[deep breath]
But that’s what makes the most sense to me,
hopefully I got that right.
So there are frogfish that have lures that look like typical worms,
lures that look like feather worms.
Sorta.
Lures that look like small fish.
I guess.
Lures that look like tiny shrimp.
Supposedly?
And lures that look like amphipods.
OK, this one I can kinda see, but the others?
[noise of uncertainty] Maybe if we see them move, it makes more sense, like…
OK, this definitely looks like a fish to me. This one’s definitely supposed
to look like a worm. And I think this one is supposed to look like a shrimp?
I think?
It looks like somethin’!
And.
And!
Apparently, frogfish also release chemicals into the water that makes
their lure smell good to prey, and the lure of at least one frogfish
is capable of biofluorescence.
Which is not the same thing as bioluminescence, which their deep-sea
anglerfish cousins do, but I don’t got the time to explain the differences
here, so if you want to learn about bioluminescence in specific,
go check out my videos about dinoflagellates.
Otherwise, pause and read this.
Anyway!
Some researchers found that the worm-like esca of the Hairy Frogfish glowed bright
orange under certain lighting conditions, and as you can see in this video, there
are worms swimming around that are nearly the same size as the frogfish’s
esca, and they glow bright orange, too.
And all of this is aggressive mimicry.
Like, AGGRESSIVE mimicry, right?
Frogfish are pulling out all the stops.
They’re not just making their lures look like other animals, but also
move like other animals, smell like other animals, and sometimes
even glow like other animals.
Combine that with their aggressive resemblance, so looking like a
nice, cozy, unoccupied bit of rock that also might be covered in
really tasty algae, and frogfish are just…
prey attractin' MACHINES.
They’re like the perfect vacation home with all the amenities.
Step aside, AirBnB, we got…
Water F…n…F now.
That was a really bad joke.
Of course, attracting prey isn’t enough to make you a good predator.
You gotta be able to catch it, too.
And frogfish have got catching their prey on lock.
So there’s three recognized phases to frogfrish kay pratcher.
What?!
So there’s three recognized phases to frogfish prey capture.
Phase 1 is the pre-strike phase.
This is when the frogfish spots something it wants to eat, and
when they might bring out their lure, cuz they don’t always use it.
If their prey is already nice and cozied up to them, then the
frogfish will just go for it.
Aggressive resemblance in action.
Sometimes, frogfish will just move very slowly towards their prey, going
completely unnoticed, then hork them down.
Camouflage in action.
But about 80% of the time, they’ll bring out their lure.
Aggressive mimicry in action.
They’ll often dangle their lure directly in front of their mouth, but
sometimes, if their victim is kinda off to the side, they’ll dangle their
lure on that side of their body, and then flick it over to the other.
Basically making their prey move directly into their strike
zone to go after the lure.
Very clever, little frogfish.
Phase 2 is the strike phase.
It’s how they get their prey inside their mouths.
Which doesn’t sound very interesting, right?
Cuz like, whatever, they open their jaws and eat it, just like everything else on
this planet that has a mouth, but oh man.
Let’s talk about frogfish mouths.
Cuz there’s a lot going on with their oral cavities.
So first off, many fish have to expand their mouths by several
sizes in order to catch their prey.
I’ve already talked about this in my moray eel video, but basically, when a fish
rapidly expands its mouth, it creates negative pressure, aka suction, that
pulls in prey and whatever else is nearby.
This is called, and I’m not kidding,
gape and suck feeding.
Gape and suck.
Is this also the name of some Midwestern gas station or a fast food joint
out of the Simpsons, or the title of something that only grown ups should
be exposed to and I’m not gonna elaborate further
because I don’t want to get demonitized --
gape and suck?!
Gross!
Whoever came up with that term is fired.
From everything.
From existence.
Anyway, when it comes to…
this way of eating, the bigger your mouth is and
the faster you can expand it, the more successful you are in capturing prey.
And frogfish have big mouths, and they open them fast.
They can expand their oral cavities to be 12 times larger, compared to
when they’re closed, and they can engulf their prey in 7 milliseconds.
Which, I know without context just sounds like random numbers,
but this is literally unheard of.
Out of all the fish mouths that have been examined, frogfish can
expand theirs the most, by far.
Other fish have been reported at only being able to expand their
mouth to be six times larger.
And engulfing prey in 7 milliseconds is wild.
There’s only a handful of other fish that can eat that fast, the Lined
Seahorse and the Dusky Pipefish.
And for even more context, do you know how long it takes for a human to blink?
100 to 400 milliseconds.
In the literal blink of an eye, a frogfish can, theoretically, get
60 different things into its mouth.
And I could say a very dirty joke right now.
And we have no idea how they can move so fast.
Scientists have dissected frogfish heads and jaws and as near they
can tell, their mouths aren’t built any different from most other fish.
Some researchers hypothesize that there might be a sort of catapult mechanism
in their jaw somewhere, similar to the mechanism fleas have in their legs to
jump, but no one’s found anything yet.
Once the prey is in the mouth, we move onto Phase 3, Prey Handling, or the
manipulation and…deglutition of prey.
Well, that’s a word!
Deglutition.
DEGlutition.
DeGLOOOOOOOtition [giggles]
Since frogfish eat things whole, sometimes they gotta rearrange the food in their
mouth before they actually swallow it.
And they use their pharyngeal teeth to do that, or teeth that line their throat.
If you’ve seen my moray eel video, you’re kinda familiar with pharyngeal
teeth, because moray eels have pharyngeal *jaws* that lunge out of
their throat and into their mouths when they’re eating something, and
if you’re watching this right now being like, “Moray eels have WHAT?
That do WHAT?”
Go watch my moray eel video.
And while pharyngeal jaws are unique to moray eels, pharyngeal teeth are not.
Most fish have teeth that line their throats, and frogfish are no different.
If they need to manipulate their prey, they’ll hold it with their main teeth,
the ones in their mouth, and then, through a racking motion, pull their
prey, either head or tail first, down their throat using their pharyngeal teeth.
Also, I have no idea what the heck a racking motion is.
And I didn’t misread it, it’s not a rocking motion, it’s a racking motion.
So if anyone knows what that looks like, please let me know in the comments.
However, if the frogfish manages to inhale their prey when it’s facing them
head on, or it’s small enough, it will be immediately sucked into the frogfish’s
stomach, no pharyngeal teeth needed.
Then, a sphincter in the frogfish’s esophagus quickly closes,
preventing the prey from escaping.
So, like, think about that.
How terrifying it must be to be eaten by a frogfish!
You’re just chilling next to a rock, minding your own business,
when you spot this tasty looking worm out of the corner of your eye.
You move in for a closer look but suddenly, you’re thrust into perpetual
darkness, and the only source of light is rapidly closing behind you.
And you have no idea what just transpired because it all happened in 7 milliseconds.
And in that darkness is where you will die, slowly and painfully, as the frogfish
who doomed you to this fate goes about its life, oblivious to your suffering.
[deep breath]
Aaaaah, nightmare!
That’s like something out of a nightmare!
Frogfish are the darkest of dark horses.
They’re so goofy and they’re so awkward and they’re so terrifying.
And I love that, I love when some derpy looking animal is actually
way more impressive or formidable in a way that no one expects.
I mean, seriously, if I showed you these three predators and asked, “Which one
do you think catches its prey 91% of the time?” would you guess this one?
Well, you probably would…now, cuz you’ve watched this video, but like, before!
Like if I asked you that question before you saw this video,
would you still say the frogfish?
Cuz I wouldn’t have!
I had no idea they were so good at eating other creatures until I
did the research for this video.
On the surface, they might seem like they’re terrible at being
fish, but in my opinion, they’re one of the greatest in the ocean.

Thanks for watching another episode of Alien Ocean!
I know it’s been a while since I made a video, so thank you, everyone, for your
patience, and to my Patrons in particular, some of whom are scrolling by right now.
I have been dealing with some pretty debilitating health issues the last
few months, both physical and mental, which I’m not gonna get into here, and
I wish right now I could say something like, “Fortunately, these issues have
been resolved and I’m gonna be releasing videos on a regular schedule again!” But
they haven’t really been resolved, and I don't know when I’m gonna be able to
release my next video which…sucks, y’all!
I really like making videos and it really sucks when I’m
not healthy enough to do that.
And, on top of that, if I’m not releasing videos, I’m not making a lot of money,
which is also, y’know, it’s own problem.
Soooooooooooo if you have the resources, please consider joining
my Patreon, which is definitely the best way to support me directly.
Depending on which tier you sign up for, you can get early access to my videos,
or your name in the beautiful credits.
But any contributions will be deeply appreciated because you'll be
supporting me through a time where it’s really difficult for me to work
because my body is being…stupid!
Having a corporeal form is so overrated, y’all.
If you currently are some sort of disembodied sentient being
and you’re thinking about maybe getting a corporeal form, don’t!
It’s not worth it.
Anyway, be sure to like, share and subscribe and all that, follow me over
on Twitter, and until next time, this is your friendly neighborhood Octopus
Lady reminding you that you don’t have to go into space to find aliens.
Hey, so, I found some photos I wanted to use in my video but couldn’t find a good
place for them so I’m putting them here.
Like this one!
Someone needs to caption this.
Like, “Me.
My super cool and extroverted friend who adopted me for some reason."
Or, "Me!
The baddie I pulled by telling them weird marine biology facts."
I dunno, come up with your own!
Down in the comments.
Frogfish either look like they’re the perfect example of “Not a single
thought behind those eyes” or they’re having THE most existential crisis
to ever existentially crisis about.
This is a baby warty frogfish and look at her!
She’s tiny!
She’s smol!
She’s WEEEE–!
