Meet the unsung climate heroes in the deep sea: Acorn worms

- Опубликовано: 11 июн 2024
- Twisting and turning atop the muddy ooze, the acorn worm (class Enteropneusta) is an unassuming worm-like animal that has a surprising connection to Earth’s climate. Named for their acorn-shaped front end, enteropneusts are actually more closely related to humans than to worms. They have a rudimentary nerve cord that is similar to ours, and they breathe oxygen using structures similar to a fish's gills.
A constant rain of particles connects the ocean's surface to deep-sea communities far below. Carbon dioxide from the atmosphere mixes into the ocean at the surface. Tiny plant-like plankton transform carbon dioxide into organic material and are then eaten by larger animals. As these animals eat, poop, and die, they create a flurry of organic material known as marine snow. The sinking snow moves nutrients and carbon all the way down to the deep seafloor, where bottom-dwelling animals, like acorn worms, enjoy a bountiful feast. This cycle is known as the biological pump.
Acorn worms are connected to us through the carbon cycle. They play a significant role in the redistribution of sediment and nutrients in deep-sea communities. As they do their part to help regulate climate, we can do our part by drastically reducing our carbon dioxide emissions. The ocean is a powerful ally that has buffered us from the impacts of climate change-now it is our turn to act on climate change to safeguard the future of the ocean and its inhabitants.

MBARI should really start a mini doc series, this is so relaxing
Relaxing, informative, he got all the tools
You might enjoy the docs at Natural World Facts. Leo Richards uses clips (with permission) from MBARI and others to create some stunning and totally relaxing videos.
Thank you for making Japanese subtitles!
Usually I could only enjoy the video, but this time I was able to listen to the commentary, which made it more enjoyable than usual!
I would love to know more about them!
Beautiful vid, always something facinating on the channel
Fascinating. Thank you for educating us. MBARI! We want more content!
Wasn't sure what to expect 😮. Must say I was quite surprised and appreciated the brief lesson. Thank you.
Fine! I'll play Subnautica again.
Huzzah for detritivores! I hope I spelled that correctly.
I'm curious as to the last half/third of these animals - Comparing the different clips of them in different stages, I am guessing the intestines or colons of these acorn worms are transparent and the sand-coloured structures inside their bodies are actually just the sand itself as it works through their gut?
🤔 Would they be considered an aquatic "indicator species"? Similar to terrestrial frogs, owls, mayflies, etc?
Yes, many deep-sea animals are indicator species and it is critical for us to understand how these communities are impacted by our changing ocean.
You had me at 8 foot worm
Yay for deep-sea climate heroes!
Everyone is worried about harmless co2 when we are dumping inorganic waste
I used to call these things "spiral-poo worms"
We’re just glossing over how they’re eight feet long, huh? Cool cool cool. I should make a life-size plushie ragdoll of one.
It's January 9th, 2024 and I will comment a common, well known "Spock" quote by saying:
Fascinating.... 🤨🤔🖖🖖🖖
That was legit
Due to their cool circles they make, I suggest we name them, "Fibonacci Floppers".
Kor subtitle plz 😢😢
Chickens of the sea
Worm is not a taxon, so the phrase _"more closely related to humans than to worms"_ is essentially vacuous nonsense.
it is assumed that people would be thinking of specifically earthworms when they say "worm"
i wonder if anything eats these guys
THE CLIMATE IS ALWAYS CHANGING!!!!
Typing in all caps doesn't make you more correct, it makes you more obnoxious.
Climate refers to the general weather conditions in an area, so weather, not climate, should be changing. Unfortunately, climate change is real. Global temperatures continue to reach new records as a result of human-produced greenhouse gases, which has had devastating and destructive effects on climate.
There is a better name: Rapid climate change.
Referring to how the change in climate is currently going much faster than it should be, and that is the concern.
@@astick5249 "Climate crisis" feels very accurate as well.
THAT DOESN'T MEAN MAKING IT CHANGE _FASTER_ IS GOOD FOR YOUR HEALTH OR WAY OF LIVING!!!!!.
Sounds good . Let’s just not push EV cars are good for the environment either ;)
On they whole and over the course of their life, yes, they are.
@@phonotical trains are better than cars full stop.
@@cryptbeast3222 sure, but there aren't enough trains for everyone
@@phonotical The system can be expanded for most people. It's more efficient and makes far more sense than cars everywhere.
@@phonotical So then make more trains
What are you telling us to reduce carbon dioxide? Why isn’t this video in one of the languages of China or India? We’ve reduced our emissions while they are increasing theirs. It’s not a warm environment that’s killing people, it’s the cold when people can’t afford to heat their homes. Damn cultists.
Wondered how long it would be before the first idiotic, it isn't us, one of the biggest nations on earth, true cultists.
You all have a part to play, and just because the video isn't available in other languages, doesn't mean they're pointing the blame at you, if you want to find them to have other channels and redub their videos into other languages, something they can't do for free, you go right ahead, otherwise keep your mouth shut and read a book.
While I get where you're coming from, thanks to the political BS, it's more than likely he's only saying 'we' as a general encompass for everyone. You're just feeding into it by getting tilted over a couple words.
Compare Population (2024 World meter) & energy use (consumption) per capita (2021-wiki)
India population: 1,428 Mil. -- 7,143 kWh/person
China population: 1,425 Mil -- 31,051 kWh/person
USA population: 340 Mil. -- 78,754 kWh/person
And the USA should be proud for reducing carbon emissions by less than 2%? The UK consumption is on par with China. Perhaps if we were paying anywhere close to what the UK pays for petrol(gas) then maybe, just maybe we could make a dent in our consumption which quite apparently is bigger than our waste lines.
