The Layers of the Ocean

We've gone over the structure of the earth, including continental and oceanic crust, but there is a vast ocean that sits atop that oceanic crust. If we want to understand every area of Earth's surface, we will certainly will have to discuss the layers of the ocean. How far down can light reach? What happens to the temperature and pressure as we venture down? What kinds of organisms might we find? Let's dive in and find out!

i often skip over videos about things i already know, but i do watch yours, even if i don't learn anything new you will have given me a great way to explain a difficult topic to a lot of people. i appreciate all that you do.

Thanks Dave for explaining the layers of the ocean.

As usual brilliant and informative.
I like your style prrof. Dave. No sign of " sensational" wording, just the facts.
I always feel i learn something

[tygerbyrn]

I love the colorful illustrations. Visual appeal and informative to the max! Keep up the great work! 👍

Question: how can angler fish attract prey with light if presumably all their prey is blind? If the prey isn't blind, what use are their eyes without any sunlight?

Thanks Professor Dave, interesting subject indeed !
I was wondering if you're willing to do an episode about insect taxonomy as I'm an Entomology student and I always feel that it's a subject doesn't get mentioned so often.
It would be really great if you did that !
And I'm sure you'll find it fun :D

And thanks again for every video you've ever done as I watch a lot of them and not only the one's on Biology.

Thinking the next video will be on marine volcanism and touch on some chemotrophs! The ocean stuff is so fascinating (and horrifying), it would be neat to explore in another series on it's own, or maybe limnology instead. Lakes are full of interesting cycles and food webs.

I am amazed to have found out they found life in the Mariana Trench, just amazing how resistant life can be.

I can never explain how much I appreciate your videos. I swear you're my favorite YouTuber. From debunking fake science, creationism nonsense and just general scientific education. I love it all! Thank you.

earth is weird, awesome, and scary. I've been on mountain roads so high it hurts to breathe, with breathtaking views to match. endless walls of dark green pines so close together it looks like a blanket.
I can hardly imagine such immense depths. point being, most of the time the natural world has this eerie way of making you feel quite small. and this is just one planet out of who knows how many.

[livignij]

Just got your book, excited to start it.

[Rryan]

Fascinating topic, enjoyable video. Good job and thanks Dave!

[evilotis]

absolutely fascinating, as always. thank you so much for everything you do <3

It's amazing how sea creatures start looking more like nightmare fuel the deeper we go.

[Ensaima]

You will allways remain my top 1 favorite youtuber. I would love to have you as a teacher

[subbss]

Everything about Earth's oceans fascinates me, so I am looking forward to more, either about geology or zoology. Cheers Dave. :)

Hey man haven't seen ur stuff in a while and tbh I think you're one of the best science educators out there. There is an unbelievably immense difference between how you and other real science people approach subjects, and the Dunning-Krugers that you've debated in the past, who prop up absolutely no footnotes where due.
That being said, I now know a bunch more about the giant ball of rock and water we're currently living on :) THanks

Also... what would happen to the animals from the Abyssopelagic if they'd come to the stores. How would they morph to hundreds of times less their usual pressure lmao

[backstreetfan]

I liked the part about the tan bristlemouth fish because I have never even heard of that fish before

[jovanabogdanovic]

Came here from the math lessons! You are the best teacher!

"It is home to only tube worms and sea sponges" Snail fish would like a word with you.
