We're happy to hear that you enjoyed and learned from our video. Also, thank you for the suggestion about transcribing our videos for the hearing impaired. We've added captioning to this video and will do so for all of our future TH-cam videos.
The comments here are mostly missing the point. They say "well, if there are no jellyfish, then what are they?" The video is not here to say they don't exist - the video is only here to say that "jellyfish" is not a taxonomic term. A classic sea nettle, for example, is a jellyfish, but closely-related corals are never called that, while Comb Jellies are sometimes called jellyfish. You see? The term "jellyfish" is not very helpful as a taxonomic description. It would be better to call some of them "medusae", others "comb jellies", and so forth, as the term is mostly just aesthetically descriptive. Shoutout to @moara for actually making an educated definition and defence of the term (unlike most of the commenters).
“aesthetically descriptive” you mean it actually describes the organism? unlike taxonomic definitions which are so broad you could say humans and fish are the same? Be careful with with what you say man.
@@slenderman3310 _...unlike taxonomic definitions which are so broad you could say humans and fish are the same..._ Except that scientists do *not* say anything like that. Modern cladistics (which is in the process of replacing the old Linnaean taxonomy) simply, and strictly, catalogs organisms according to ancestry. Every creature descended from a common ancestor is viewed as belonging to a single clade. Clades slot naturally into nested hierarchies, with clades of more closely related organisms being nested within those of broader, more generalized ones. Yes, it is a fact that "fish" and "humans" are both (at a minimum) members of _Animalia_ (animals), and _Chordata_ (creatures possessing nervous systems). One branch of _Chordata_ did evolve into _Osteicthyes_ (bony fish). One branch of that became _Sarcoptergii_ (lobe-finned fishes). One branch of that became _Tetrapoda_ (four-limbed vertibrates). And one of the many, long-evolved tetrapod descendants is _Homo_ (us). But none of that means that "humans" and "fish" are the same. It only means that both groups share a common ancestor somewhere in the long distant past, and can be considered long-separated (~380 million years) cousins. However, that brings us back to the OP, who correctly pointed out that words like "fish" and "jellyfish" are casual, paraphyletic, terms, meaning that they are hodge-podge categories that do not accurately describe their members with any kind of formal accuracy. By "aesthetically descriptive" (admittedly an odd choice of words) he meant only that people have generally categorized these groupings through superficial visual similarities (i.e. "it looks like a fish to me"), as opposed to scientific taxonomy, which takes a much more detailed and nuanced approach that focuses on how creatures are actually related. If you are at all interested in really learning something about scientific classification of humanity, go find Aron Ra's 50 part _Systematic Classification of Life_ series. It literally goes step-by-step into how the earliest life eventually became "man" (and many other creatures along the way). It is long, but well-worth the time spent watching.
The Narcomedusae are the jellies whose tentacles point ahead of them instead of pointing behind like most jellies. The little yellow one in the video with 4 tentacles pointing ahead is called Aegina citrea.
A jellyfish has a ring of muscle around its bell. When a jellyfish tightens this muscle, its bell closes. This pushes water inside the jellyfish out, shooting the jellyfish forward. As the muscle relaxes, water refills the bell. This is how they pulse in the water. Each tentacle can be moved by its own muscles, as can the oral arms. Jellies have a nerve ring that connects the rhopalia (sensing organs) and a nerve net that can send messages around the bell to contract and release.
@@raccoonchild I know we other sphincters. They’re like valves that can open or close to control the flow of substances through the tube or passage. The anal sphincter somewhat can be visible as the others are inside our bodies.
There is such a thing as a jellyfish. It's the medusa stage of any Cnidarian. Everything else is gelatinous zooplankton or sea jellies, but not necessarily jellyfish. Folk taxonomy does not have to follow the same rules as scientific taxonomy. Jellyfish can be a polyphyletic grouping and still be valid in people's conception of life. As long as people realise it's a cultural term, and not something based in our current scientific classification system, I don't think there's a problem using "jellyfish".
moara I am assuming this video is targeting the more simplistic view of most people, as I flatly refuse to believe that the creators are blind to this. I sincerely hope that these aren't the discussions that go on at a research institute, considering the abundance of organisms in this environment with gelatinous bodies. I'm not going to lie; I felt rather insulted/surprised when they tried to make an arguments for tunicates being jellyfish, and it only got worse from there.
Those creatures always fascinate me, there are also a lot of so called “jellyfish” that haven’t been discovered yet. Maybe someday we might discover more species of these deep sea creatures.
I feel like the title of this video is a nod to Stephen J. Gould's statement that "There's no such thing as a fish!" He was also referring to convergent (and divergent) evolution of multiple branches into things we all lump together as "fish." (This came to a much wider awareness when it was quoted on the QI panel show.)
This video is perfection in every way. Footage, information, the subtle audio track.. I’ve been subbed to this channel a long time, how I never got to this magnificent document until now I know not. A gem
+cometkite You wouldn't think so, but people lump salps in with jellyfish when it is convenient. www.sciencedaily.com/releases/2012/02/120201181222.htm
I am curious how jellies and all other animals will be or will they be gone when in the new world to come. Know only some humans that can adapt can be in the new system free world. Maybe we make new animals or let adapt some old ones?
Thank you so much that video presentation was a work of art, and a testament to the work of all of those who worked together to capture this incredible deep sea footage. 👏🏼
I especially appreciate the nomenclature assistance via the graphics. This is a really nicely thought out and informative video. Thanks for this TH-cam channel and and for Jellywatch! PS. Please consider regularly transcribing your TH-cam videos for the hearing impaired.
That one with the strobing colored lights just blows my mind. How crazy is our world that we have fish that have adapted to strobe colored lights underwater? Science is so awesome.
Terrific video man. I always thought the same. It always seemed to me the term "jellyfish" was just lazily thrown out there for the meantime, while these gelatinous-like organisms from every branch of life were truly and more accurately classified.
One of the facts that I found to be interesting while learning biology in college is that some "jelly fish" can essentially be eternal. Going from the polyp stage back to the medusa stage. Medusa stage back to the polyp stage..
Wow, I learnt something - a beautiful video about several groups of impressive animals - I was unaware that some fundamentally different animals would be evolutionarily convergent - having a jelly form. Thanks for this video.

Thank you so much for uploading this very educational video. I learned the basics about cniderians, mollusca, and polychaetes in my Zoology course, but it never occurred to me that they could be bunched together as "jellyfish".
I love this channel but this was one of the best videos. I really hope to see more in this style. It was very educational and interesting to watch. I love learning the names of these animals and where they fit in the tree of life, GREAT video. Thanks!!
The term jellyfish is ambiguous, but I am not sure that in common usage it is ambiguous as is implied in this video. I think in common usage it is limited to members of the cnidarian phylum that have a medusa stage or it is limited to describing cnidarians that are in a medusa phase of the organism's life. The meaning of the term "jellies" which was perhaps intended to replace the term "jellyfish" (for dubious reasons IMO) seems to have been extended so that it now is a term that describes creatures that have gelatinous bodies but I have never seen the meaning of the term, "jellyfish", extended in a similar way except in this video. Regardless, the video was great. Thank you.
The video is brilliant! Thanks very much for such detailed information. However, the subtle tone of the narrator's voice and meditative music are making things a bit sleepy at the end.
Lovely video. its shame it dident go into further detail discuss some other scyphozoans such as the Rhizostomae. they are pretty different looking when you compare them to the semaeostomae. or has there been some revisions to the taxa since last i checked?
Remarkable. So much stunning diversity. Also worth noting is how many jelly-like organisms can also be classed by how they just go with the flow, or have any one of a plethora of methods of maneuvering themselves through the water. Definitely avoid *Box Jellyfish* - those weird twelve-eyed lethal hunters, with millions of nematocysts both on their bell & metre-long tentacles - especially the nightmarish *Irukandji* ⊚. _If you visit _*_Australia_*_ (northern _*_Queensland)_*_ & see the signs warning you not to swim at that beach, bloody well pay attention..!_ ⊚ Which apart from causing unbelievably agonizing welts & scars, tachycardia & increased blood pressure, also comes with a range of psychological effects, including the terrifying "Feeling of Impeding Doom", which has almost driven people to suicide...
Could listen to this voice all year. But even better would have been much more, longer, screen-filling jellyfish in between the diagrams. Jellyfish is a legitimate nomer for see-through sea-creatures in situations where transparency is of supreme interest, I’d say. 😉 Thanks for the content!
I struggle continuously with the categorization of siphonophores as colonial animals. When the sub-units cannot function on their own, it seems to me that the animal should be considered as one complex organism, rather than a colony of simple organisms.
I want all of your source video. ALL OF IT. I want beautiful HD videos, hours long, of these phenomenally gorgeous creatures. How could I even begin collecting such video?
Excellent stuff. I'm gathering some reference photos of these things, to study them as training for visionary art. The names help a lot. Fantastic source of inspiration, thanks for uploading.
hey many sea jellies eat adult fish and even other jellies! did you forget about the group of jellies called cubazoans? did you forget that people in Asia eat sea jellies, salp jellies are in the same group as humans, and many jellies reside in freshwater lakes and rivers!
I remember going to the Monterey Bay Aquarium as a kid and being so entranced by the jellyfish exhibit (tho I know it probably contained many organisms that may or may not fall under that untaxonomic description). I would love to go back at some point.
"Everybody is familiar with the basic idea of a jellyfish. Some kind of abstraction. But there is no real jellyfish. Only an entity. Something illusory. And though you may see an amorphous brown blob stranded ashore, and you can feel the sting of the tentacles' cnidocytes, and maybe you can even sense a certain beauty in the mesmerizing bioluminescence, they simply are not." -MBARI
There might be no jelly fish in high level conversation and journal articles but that's about it. Can't really get rid of low resolution concepts just because we have assemblies of high resolution concepts because you have to start somewhere conceptually. Cool video though
I thought the common red and blue coloration was because those colors "disappear" in various deep levels of water because of the frequency of the light waves.
this is some animals which old textbook (70s) didn't introduce much when i was a kid. we see them all the time, even eat some species, but with zero knowledge about it.
Thank you for this wonderful video. I have not heard this vocabulary pronounced since college. Back in the day we rarely had such good video to augment the text books.
MBA: makes video clarifying that technically jelly fish don’t exist Also MBA: devotes so much tank space to jellyfish that it’s become rather boring if you want to see anything but jellyfish
Their colour might hide the preys light show, but not necessarily that's what it is for, it could be just that the colour red vanishes fastest when you get into a decent depth of water, meaning they have a larger hunting area, or that their pigmentation is the cause of some build up of what they consume, eat only carrots, you too will start looking pretty orange!
Some science fiction writers have postulated that, if there is life on Jupiter, it would be jellyfish-like creatures that swim/float around in the thick Jovian atmosphere, presumably eating each other for sustenance.
Irukandji jellyfish... i was watching you're video and i remembered a documentary from several years ago that focused mainly on the very dangerous but small Irukandji jellyfish. found mostly in Australia. i hope never to experience the affects of being stung by one as they are difficult to spot and extremely painful. even fatal in some cases. thank you for this great video. 🎐😱

Fish is a menu item, not a taxonomic description.

Whatever you call them, they surely are beautiful animals.
Does anyone know the soundrack of this video please?
I thought the common red and blue coloration was because those colors "disappear" in various deep levels of water because of the frequency of the light waves.
Cnidarian medusa are the only animals I would call jellies. Worms, tunicates and snails aren't jellies.
Am I the only one getting “Making Christmas” at points in the the background music?
Wonderful, even for insiders!! How do you know about the 1080p HD setting?
I can imagine people also might call a free-swimming crinoid a jelly, and tunicates/sea squirts can be pretty gelatinous, though they are sessile.
This is going to end up being key as my life story builds to the climax.
