As you can imagine, this video took especially long to get together so your patience is very much appreciated. Got a HUGE video planned for our 3 million subscriber special. And once again, BIG thanks to @LindsayNikole

Zeus: Can you imagine living among humans?
Hades: Try living among dead humans.
Poseidon: That's cute...

The ocean is like a cute looking indie game. It looks harmless on the surface, but the deeper you go, the more horrifying it becomes.

[Vinciini]

"You're seriously underestimating the ocean's ability to massacre your mental health!" GREAT LINE!

[Mewter_YT]

“Detecting multiple leviathan class creatures in the region. Are you sure that whatever you’re doing is worth it?”

[pjsmith]

It's crazy how within my lifetime we went from having no footage of giant or colossal squid, to now having footage of divers just casually swimming alongside them.

[adan_vd]

I absolutely love casual geographic and Lindsay collaborating, best crossover

[spicylime]

"And the biggest predator that isn't a disgraced former youtuber.." this has to be the best line in this video lmao

[camilaisalawliet]

bro the dead by daylight skill check sound at 16:10 literally sent me into a full panic--

[funkysanta]

A close friend of mine was an ex Navy diver. He told me that him and his fellow divers always hated night dives. The ocean looks like a vast infinite pool of black ink. Its a cold, deep, dark abyss. The only thing they ever look forward is ending their dives, resurfacing, hauling onboard the ship, taking off their diving gear and wet suits, and finally heading to the hot shower. The hot shower is probably the only place that feels like it can wash away the night diving experience. Even experienced Navy divers would shudder after coming up after a night dive.

I never get tired of actual marine biologists bullying this animal 😭

[carlsoto]

As someone with thalassophobia, thank you for confirming that my fear of the deep is completely rational and scientifically justifiable

[teuthistalks]

When I was a kid, I was really really into deep sea animals (I still am.) I actually recognized a lot of these critters, thank you for making a video about them!

I think this is the first time I’ve ever seen someone talk about the praya dubia on YouTube. It’s so eerie but cool! IIRC, their hunting strategy is basically acting like a sideways jellyfish - they take advantage of their long length by deploying a curtain of stingers below them.

For anyone curious about the angler fish mating, first of all, horror warning.

Secondly, the male angler fish are much smaller and lack any of the attributes that help their female counterparts hunt (light, powerful jaw, sheer size ect. ). So their only chance at survival is finding a female.

Once they do, they give her a hickey and just don't let go. Somehow, rather than destroying the invader, the females immune system accepts the male into her body.
After this, the males jaw melts and he becomes completely merged with the females body, he then gradually starts to shrivel up in order to remove all non essential organs. Eventually, he is fully integrated into the female and survives directly from her blood flow, like any other of her organs.

There can also be multiple males attached to a single female.


So yeah, male angler fish are essentially just the testicle DLC for the females.

This crossover makes the most sense, now we just need one with Lindsay and tier zoo and we have the holy trinity of zoology

[hpsgdg]

I can’t stress enough two things:
1. You two collabing is always an absolute gem
2. You giving spider warnings saves my life every time

[wafflesthearttoad]

I saw the collab name and got so excited because I first found your videos, and then found Lidnesey’s videos while trying to find some zoology stuff to study whilst studying simultaneously for a chemistry exam that was the day after (kinetics and electrochemistry yaaaayy)

And then I see you’ve both collaborated and I am happy :)

[Werewolf.with.Internet.Access]

Somewhere in the afterlife, Steve Irwin is watching Casual Geo and Lindsay work, with a happy tear in his eye and smile on his face going “good on ya, mates”

[adeptgirl]

Casual Geographic: I'd rather eat ten pounds of Popeyes biscuits with no drink than go in the deep ocean.
Lindsay Nikole: THIS FISH IS MY SON AND I LOVE HIM

This collab has a lot of good energy, thank you both so much for creating it. Also, TIL that lizard fish are a real thing, the deep sea is so full of cool stuff wow!

[purplehaze]

What's even more upsetting about humboldts is that they're just as clever as many other cephalopods. A humboldt squid once tried to physically pry the mask off a diver in order to drown him.

[Thiriously]

Absolutely love you and Lindsay scaring us with the deep ocean, was really great to see you guys sort of going back and forth <3
