“Hey man you hungry?” “Nah, I ate a piece of dry wood 3 years ago.”
-
13:45 "Relatably, when giant isopods find a significant food source, they gorge themselves to the point of compromising their locomotive ability." Damn, ive never felt so similar to isopods in my life. Thank you narrator.

"Detecting multiple leviathan class organisms in this area are you sure whatever your doing is worth it?"

From the Greenlands Shark's point of view, it had been swimming around in the deep ocean for a couple of centuries when suddenly, the water started getting warmer. Then plastic appeared everywhere. Finally, on a single day, it felt thousands of shockwaves coming from everywhere. After that, the plastic gradually went away and the water went back to normal temperature, and the greenland shark swam around for a couple of centuries more, wondering what the hell that was.
-
I always wonder, if these deep sea creatures still have functioning eyes at these depths they must be ridiculously sensitive right? So would the intensity of the lights on the rovers be as bright for them as us staring at the sun?
-
When I was a child, my parents took me with them on a family vacation to Tahiti. In the airport, my dad got me a book from a newsstand that was an illustrated dictionary of sea creatures. Surprisingly, despite being a book meant for kids, that dictionary contained a vast array of ocean animals that most people have never even heard of. Both the Greenland shark and the vampire squid were in that book, and I still remember them from reading it all those years ago.

You forgot to mention the fact that the crustacean that digs into the Greenland sharks eyes acts as a lure so that the Greenland shark gets easier meals even though it makes them completely blind it truly doesn’t change much because the zone they live in receives so little light it doesn’t change really anything for the shark
-
Hey new viewer here and don't comment much but just wanted to say this video is spectacular, grabbed my attention from the moment it started from the in depth descriptions to great narrative of the subject. WITHOUT constantly repeating what has been said before to simply increase the video duration. This was a spectacular job in editing and information delivery.
-
Interesting thing is that in so low temperatures many chemical reactions are slower or non existing. That would suggest that those creatures not only live longer but they are living slower. I bet that such a gigantic pressure also adds to this effect.
-
"Gravity" is somewhat of an abstract concept when you can maintain neutral buoyancy in your "atmosphere" (in this case: the ocean). It's easy to weigh a lot when you don't actually have to support all that weight with your body.
-
"The thought of swimming around in pitch black with crustaceans in my eyes for 500 years gives me heebie jeebies of the highest order." Quote of the year for sure
-
Speaking of "marine snow", another big event that actually changes the ecosystem of the Abyss for decades is a "whale fall". It's when a whale dies and goes through the process of decaying. The entire process takes around 60 to over 100 years to complete and feeds just about every level of the ocean in the process.
-
I had no idea there were vertebrates that could live up to 500 years. That is incredible! Definitely need to look into the Greenland shark now.
-
Imagine if the Sea Creatures had their own city and language and we are basically aliens to them making them tell stories of mysterious objects that had blinding lights go down and observe them for hours
-
Having the advertisement at the end of the video is great it’s not intruding on the educational aspect. Earned my sub.
-
This YouTube video is better than most documentaries I've seen anywhere over the last few years. So well done, thanks for uploading 👍
-
This is the exact topic I wanted this channel to cover ever since I discovered it a year and a half ago, thank you for covering some of my favorite creatures that swim this planet with us. Keep up the wonderful work!
-
The Colossal Squid somehow feels even more terrifying when you know it's not hunting. Just a huge pair of jagged tentacles lunging out of the darkness, grabbing something, followed by complete silence for several months.
-
That was amazingly well done and super informative, loved it
-
I have both a deep fear and respect for the sea. I'll gladly swim at the beach, but I know that the ocean is an unforgiving mistress that could sweep me away if it felt like it
