Fun fact: In french we've always called them "Méduse"/Medusa in general instead of Jellyfish. It refers to the famously known greek gorgon Medusa, because their sting often paralyses their prey, just like her😁

[@snakewithapen5489]

I would have thought it'd be more because the tentacles look like her snake hair lol

In Italian we call the jellyfish "medusa" in singular form and "meduse" in plural form. Romance languages have some similarities ;-)

@@lucasjuliard4929 they're also "meduza" / "meduzy" in Polish, which is a completely different ballpark.

While learning night scuba diving I got a burning jelly stuck to my face. It tried to steal my cyclop and mouth piece. It was highly annoying, and then highly painful. I still (decades later) have one swollen lymphnode in my neck. It makes a cool story, especially if I spice it up by saying "at night the monster crawls out of me, and it's huuungry...". Works great with kids and kid-minded people. Story totally worth the pain.

For those wondering what the first hydrozoan was it’s called a siphonophore. Similar to the man-o-war it’s a colonial organism meaning it’s body is made up of various components that fill different roles like feeding and navigating the environment for example. There able to grow new individuals on there body to take advantage of a new food source.

Jellyfish is a genre of animal, not a biological class. Same with the colloquial use of the word "fish" in general, which as a genre could also decribe things like whales and dolphins. As a genre, jellyfish could be graded upon a spectrum of how jellyfishy they are.

[@eljanrimsa5843]

"Genre" is a word that is not commonly used and doesn't really make sense when classifying animals.

[@blaidd5917]

@@eljanrimsa5843 I pointed it out because of the fact that it isn't normally used that way. I just realised that ""Genre" decribes how people use certain categories of animals very well, where scientific definitions and informal speech can't really coexist.

[@eljanrimsa5843]

@@blaidd5917 "Genre" is used to classify works of art, not animals. A jellyfish is a jellyfish, not a genre. I guess the word for what you want to call genre is "form taxon". If you use the words in the way they are commonly used, people can understand what you mean. And nobody calls whales and dolphins fish.

I'm 37 now, but when I was in elementary school there was a book I checked out of library dozens of times. A moon jelly book that was a little fiction story but it was very informative about the life cycles from little polyp to full grown. For whatever reason I loved that book. Until just now I had forgotten all about it but this video unlocked those memories! And I remember it so vividly now 😊

[@joannbeasley3067]

One time when I was 8, I was stung by some kind of jelly in the gulf coast of Florida (I never saw the jellyfish who knows) and it felt like my leg was sliced with a blade. After my parents called the hotel’s front desk for advice, they said to put vinegar on it. Not having vinegar on hand, they made a poultice of miracle whip for my leg. Instantly fixed the problem like magic. Miracle whip worked a miracle that day

[@eyesmo]

Great episode, so glad I found this channel. If you’re ever thinking about another jellyfish episode, can’t recommend enough you let everybody know about the debt that modern biologists owe to jellyfish for Aequorea victoria’s Green Fluorescent Protein; and about how ever since GFP’s discovery scientists have been finding, engineering and ‘breeding’ new fluorescent protein varieties from it for cool applications (super-resolution microscopy, synthetic biomolecular circuits, etc). I’ve actually painted a few works of bio-art in living bacterial ink on petri dishes, with the colors coming from E. coli strains expressing different modified jellyfish proteins that glow green, red, yellow, blue, and other colors under UV light. Another gift from our alien ocean!

The "fish" in jellyfish is an old English word for, in short, any creature that lives in the water. This is why jellyfish are called jellyfish and starfish I called starfish; the creatures that live in water, and they were discovered when "fish" was the catch-all term for anything that lives in the water. The same thing can be said for the word "apple", as that was the old English word for fruit. So, a pineapple is just a fruit that looks like a pinecone. If we were to name the fruit today, it would be called a pinefruit

My idea of a Jellyfish: An extremely simple multicellular organism composed of a gelatinous material with a main Bell body , tentacles typically used for feeding in some way, and is free-swimming. I put Jellyfish alongside 'Crab' as one of those designs that just works well enough it has a million technical 'mimics' to whatever people want to call True Jellyfish. Edit: yes, I know there are the ones who spend time as polyps with some even having alternative adult forms. When they are in their not-free-swimming form they are 'not currently a jellyfish' in my book.
