Exploring Life on the Deep Sea Floor

Рет қаралды 298,603

Күн бұрын

Deep sea life must choose whether to live on the bottom, or to brave the expansive open ocean of the midwater zone. Creatures that adapt to life in the midwater zone are known as pelagic, while creatures that evolve to be well-suited to an existence on or near the sea floor, are known as benthic or demersal. These two groups could not be more different, but which is a more effective way of life? First, let’s take a look at the demersal creatures of the deep - the bottom-feeders, clinging to rocky seamounts, and burrowing into the mud.
We will begin our investigation in the shallows, and follow the ever-deepening sea-floor down to the far depths of the deep ocean. The diversity of organisms that are adapted to life near the bottom of the deep sea is immense - and far greater than that of pelagic organisms. Life thrives on every part of the ocean floor, from near-shore ecosystems, all the way to the abyss. But the deeper you go, the stranger they become.

Listen here Filly Brick, I haven’t watched that blasted show since I was in grade 2. I had a nostalgic moment at the aquarium as I was relating to things on spongebob squarepants and other second hand-sea related accounts from my childhood. I DID NOT grow up going to the ocean. I only watched the first two seasons, then the movie ruined it for me. I never watched the rest of the show so thats the extent of my sea/undersea education and I wanted to learn more by going to see some stupid fish. I thought it’d be funny for others who haven’t thought about the show since they grew up and don’t continue to watch it on Saturday mornings and have jobs and whatnot. AND I’m a minority. Now look what you’ve done, uhhh. I’m so upset...if only... Haha, that’s what you get

Hey there, and how are you this fine day? Quick question while this advertisement plays out. How do those fish that rest on the bottom, not moving much. stay oxygenated? And for that matter, how low, at those depths, are the oxygen levels?

@NaturalWorldFacts 3 жыл бұрын

That’s a really good question!! So, I’ve found some sources that explains that the burrows of some benthic fish create oxygen flows, but broadly ‘oxygen levels do not seem to affect demersal community diversity’. I think they cope by adapting to have small body sizes and large gills. But then again the oxygen levels here aren’t as low as you might expect! Freezing of antarctic seawater in winter leaves behind extremely cold, salty water which sinks and flows ALL around the world, providing life-giving oxygen to deep waters in other locations. This is the sole reason that much of the abyssal plain is not a dead zone!
