The degradation of food-falls at the bottom of the ocean can create partially chemosynthetic environments. In the case of sunken whale carcasses (whale falls), the supply of organic material supports an ecological succession of communities. But perhaps less well-documented than the scavengers at whale-falls are the creatures that rely on wood instead. When trees become uprooted by storms or ships capsize at sea, losing their buoyancy as the pressure of the ocean forces out any air trapped within, bits of wood sink to the ocean floor where they create fleeting oases of life (wood falls), including shipwrecks, like that of the Titanic. The scarcity of food in parts of the deep ocean creates an environment where very little goes to waste. The animal and microbial life that dwells down here has become resourceful, able to make the most of even unexpected resources. So it comes as no surprise that the deep ocean hosts complex biological communities adapted to thrive on this sunken wood.

  • Hi all, thank you for the wonderful comments and all your support on this film. I've just set up a Patreon for any of you interested in supporting my video creation further: www.patreon.com/naturalworldfacts I'm very new to Patreon so any feedback or tips would mean the world!
  • My man, I’m not sure how to explain it but when you narrate, it sounds almost like you’re smiling throughout. I can tell you are very passionate and these videos are favorites to many. Very informative while also beautiful and haunting. Wonderful work!
  • @UATU.
    It makes sense that whale falls would happen close to others because they die along migration routes, but somehow it surprised me. Wonderful episode as always.
  • @char2304
    Move over Sir David Attenborough, you have done an amazing job and will never be forgotten, but Leo is now going to take the reigns for the future of Nature documentaries. Leo your voice is like no other. Thank you for all you give 🙏 ❤️
  • Leo, this is easily one of my favourite videos of yours to date. The work that you’ve put in (not only this but your channel as a whole) is inspired and I cannot begin to express my gratitude for what you do. Absolutely phenomenal work mate.
  • @Emily-ck9ji
    Glad I'm getting notifications again! I've always been fascinated by whale-falls, but I know much less about wood-falls. Always happy to learn something new. Thank you for all the work you put into your videos.
  • @Fierach
    David Attenborough is one of the most recognizable and renown broadcasters today. But I have a feeling you will surpass even his star one day. Thank you for your beautiful work.
  • I KNEW your voice sounded familiar! I watched your terrarium video of you in the woods creating life in a jar and I thinking “I’ve heard this voice before” You have a very calming one!
  • @peperando8733
    I just really love your voice and commentary man, like honestly, it is such an important part of documentaries, and I think many don't realize that sometimes
  • @BigLeggedEmma
    You rank right up there with David Attenborough. Your narrations are so clean, crisp and beautiful. Thank you.
  • @ZITR0ENCHEN
    Wow you hit me with the sound at 16:08, made the appearance of the endurance even more special. Absolutely fascinating and beautifully narated <3
  • Also you should do a video about deep parts of the Black Sea. Black Sea is like a really big brine pool so it might be interesting. Edit: also Black Sea holds a lot of ancient ships from Ancient Greece and other civilizations so it would be a nice video
  • @u0aol1
    I didn't know about wood fall, this was really interesting! So nice to see you at over half a million subs man!

    0:13: 🌊 The deep sea is a food-poor environment where animals rely on food sinking from above or chemosynthesis. 4:38: 🐋 Whale carcasses on the sea-floor provide an evolutionary interface between non-chemosynthetic scavengers and specialized animals at vents and seeps. 8:54: 🐚 The bivalves Xylophaga and Giant Shipworm have evolved specialized traits to consume wood. 12:46: 🦪 Chemosynthetic microbes play a crucial role in the deep-sea ecosystem, providing nutrients for various organisms including Bathymodiolus mussels. 17:31: 🌊 The colonisers of Endurance are predominantly filter feeders, with sea lilies and sea squirts using different methods to obtain food.

  • Leo, you have got a gift my dude. You possess some god-tier skill level. its only a matter of time before some production syndicate like bbc or discovery picks you up, mark my words. I only have a passive interest in ocean biography, yet soon as I came across your channel I instantly subbed. when i first saw your face in your tide-pool episode I was legitimately amazed, never would I have imagined how young you are. I dont know where you learned how to do what you do, or how long you ended up selling your soul to the devil to acquire such talent, but you'll find no judgement here! thanks for the consistently amazing content man, your parents must simply be awestruck at what you're able to accomplish
  • I’m a nurse with excessive health problems, but what I loved more than anything was ocean life. I know just about everything you explain just from hobby consumption since childhood, but this is what I listen to at work as soon as I sit. I’ve gone through them so many times. They’re calming and somehow happy. I’m so glad you make them.
  • Do you think we’ll ever know how much we affect the ocean by over whaling back in the day? I keep thinking about that, and how the whaling would prevent whale falls from happening.
  • Your time management skills are off the charts Leo. I am forever in awe of your ability to research, write, edit, etc on top of studying 📚
