- The mushroom soft coral (Heteropolypus ritteri) is one of the most common animals we see in the depths off the central coast of California. They are abundant on the jagged walls of Monterey Canyon and the rocky slopes of local seamounts. Fast currents running along the bottom can carry an abundance of plankton and other tiny bits of food. Heteropolypus extends delicate tentacles into the currents to snag a feast. When their tentacles are extended, they resemble a beautiful flower. When the tentacles are pulled in, they look more like their namesake-mushrooms.
The abundance of mushroom soft corals and their diverse relationships with other bottom-dwelling animals tell us they are an important part of the seafloor community. But the intimate interactions among deep-sea animals only become apparent when we conduct regular surveys. We cannot protect what we do not understand. Our research is helping improve our baseline understanding of the largest environment on Earth, even if our encounters sometimes yield more questions than answers.
We still have a lot to learn about Heteropolypus, including how a changing seafloor environment will impact them and their neighbors. But we do know that a healthy ocean is one of the best ways to fight climate change. We must act quickly to safeguard Heteropolypus and other denizens of the deep. Understanding how our actions affect the ocean is an important first step. Share what you have learned, and help us grow our community of ocean champions. Together, we can protect the remarkable residents of the ocean’s depths.

A mushroom-like coral that extends flowery tentacles that glow when nudged - I wish I could keep one like a houseplant!
You are the only media source with attenborough level content anywhere on tv or youtube
I’ve watched near every nature documentary my whole life, really amazing videos
It might be interesting to know if the MBARI techniques of detecting bioluminescence at depth could be adapted by the navy to track submarines at depth complementing traditional sonar and passive sonar techniques. The passage of a submarine hull could provide the trigger for a bioluminescence response. The fact that a bioluminescence response tracts in a long straight line would indicate the passage of a submarine. The technical challenges would include detection of low intensity photons, wavelength issues, bioluminescence signal degradation due to dispersion or time. But there’s lots of very smart people in DARPA, MBARI, the DoD and the Navy that just might be able make a “biolum sonar” work.
I just get distracted naturally. Like now, I’m suppose to be studying Japanese language yet here i am finding enjoyment watching this.

Beautiful coral and a nice ocean friend to all creatures. Great video!
Cool creatures. Thank you.
Enjoyed your video and I gave it a Thumbs Up
Fascinating! Thanks for making and sharing this video.
SO COOL
Are these the standard for lab studies, mebbe coral gardens too? They do seem fragile beside all the deserved aesthetic admiration. So much awesome in this presentation!🐋
Where would the giant squid be living at in the bay ik Architeuthis prefers continual Slopes Canyons but where exactly is the best place to look?
