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. • Part 2 | Pelagic Deep Sea Life: • Deep Sea Wonders of the Pelagic Zone • DEEP SEA HUB: https://naturalworldfacts.com/deep-se... • 00:00 - Introduction: Pelagic and Demersal Life • 00:55 - Part 1: Demersal Creatures of the Deep • 01:10 - The Diversity of Benthic Life • 01:43 - The Life of Coral Reefs • 02:15 - Life at the Continental Shelf • 02:29 - Cold-water Coral and Sponge Gardens • 03:07 - Life on the Abyssal Plain • 03:29 - Advantages of Living on the Sea Floor • 03:48 - The Sea-Floor Nutrient Cycle • 04:09 - Why Benthic Life is so Abundant • 04:45 - The Extent of the Abyssal Plain • 05:00 - Deep Sea Infauna and Epifauna • 05:26 - The Role of Benthic Life in the Ecosystem • 05:53 - Ancient Crinoids of the Deep Sea • 06:32 - Benthic Fish of the Deep Sea • 07:07 - Limitations of Life on the Sea Floor • 07:25 - Seamounts Explained • 07:49 - Why Seamounts are Biological Hotspots • 08:05 - Life at Cold-Water Reefs • 08:31 - Life at Deep Sea Brine Pools • 09:04 - Life at Hydrothermal Vents • 09:31 - Life at the Bottom of the Mariana Trench • 09:53 - The Mariana Snailfish • 10:08 - Conclusion: Living on the Sea-floor is an Advantage • 10:46 - The Deep Sea Hub • Footage used belongs to Schmidt Ocean Institute, MBARI, OceanX and the Ocean Exploration Institute. • #deepsea #wildlife #nature #documentary #ocean #marinebiology #science #biology • Music Used: • Away - Patrick Patrikios • Feels - Patrick Patrikios • Simple - Patrick Patrikios • Prism - Bobby Richards • Strange the Dreamer - Savfk • Resources: • https://www.marine.usf.edu/pjocean/pa...
