The Double Life of a Fake Jellyfish 

I have a clan member called relentless jelly,I'll pass this video on lol

"as a customer service worker working in a call center that deals with sensitive private data, i wouldn’t use it. someone gave their 4 digit pin for their account to true bill and they will call the companies and will impersonate you to get a lower bill. we are very good at sniffing out fraud and unfortunately we won’t talk to these people anyway. i have called a customer to tell them this and to change their pin to prevent further access. i wouldn’t recommend it for accounts that you have autopay, stored payment methods, or your ssn tied to it." Please look carefully at your sponsor's history

My most favorite thing about the Stentor, is the golden ratio spiral of cilia to its mouth.

Sounds fair to me.

Also pretty sure it's a Finding Nemo reference when Dory finds the small jellyfish.

We love Squishy 🙂

Yes

Oh that would be cool

They also constitute an important mechanism for carbon sequestration, through jelly-falls!

thats a lot of jelly.

This is actually really interesting!

And because they are the oldest they still are very archaic, for the most part the same jellyfishes that swan among the trilobites in the Cambrian are swimming with us right now.

Not quite the oldest multicellular organisms, as multicellular algae(specifically red and green algae) fossils have been found dating back to the Mesoproterozoic but they were certainly among the first animals more complex than sponges. Also should note that we know know Cnidarians form a sister group to the bilaterians with the bilaterian ancestral genome showing signs of having double copies of major genes of the conserved cnidarian genome a signature of something called polyploidy which is common in plants but rare in animals though when it occurs in animals it generally results in the formation of a new phylum with many of evolutions most innovative features with bilateral symmetry being one of the key ones as the duplicate HOX genes allowed the formation of a second chemical gradient such that cells could "know" their position in two directions(hence bilateral) rather than just one(radial) in order to properly differentiate into the right kind of cell. At some point in the Neoproterozoic our ancestors split off from our Cnidarian cousins radial symmetry seems to have been a prerequisite for our more complex cell differentiation. Not sure where Ctenophores fit into the picture as we know know they are their own distinct lineage of animals that form their body axis and their tissues differentiate a different way from cnidarians and bilaterians. It seems likely that part of the difficulty may be that despite a surprisingly significant Lagerstatten fossil record for a gelatinous bodied animal that dates back to at least the early the Cambrian and potentially the Ediacaran modern ctenophores appear to all be descended from a common ancestor which surprisingly according to molecular clock estimates most likely lived around the time of the end Cretaceous mass extinction ~66Mya suggesting they may have been hit particularly hard a common trend among pelagic organisms. The possibility that ctenophores a similarly ancient clade of animals to cnidarians may have almost been completely wiped out by the KPg extinction really makes me wonder what sort of cnidarian diversity there may have been during the late Cretaceous that we will likely never know about.

i was thinking the same thing! makes me think of a very delicate string of pearls my grandma had

I really prefer the other hosts

@@smokeydude3 I am the complete opposite, i do not like the other hosts but i find Hank's voice calming.

Hank fart

I mean, who woulldn't love to narrate the tales of Squishy the Jellyfish

First time I saw one at an aquarium, my brain was just flabbergasted. They're so cool and alien. Really awesome!

I have pineapple jellies. I think that's what they are called. They are tiny and attach to the tank walls in their second stage They are maybe a couple millimeters long or so. Pretty interesting once I figured out what they were. I don't see them as much any more now my tank is more mature, but there might still be a couple in my overflow.

Technically cnidarians of the class Anthozoa the anemones and true corals don't have a medusae stage since they have independently evolved bilateral symmetry with more motile free swimming planula able to feed independently as a planula but some other hydrozoan corals do indeed produce medusae.

I was thinking the same thing. I was like James better be careful with that jellyfish

And what else did you have in that tank?

I don't follow your logic. The first three things you listed are very common and astronauts don't make videos of aliens (or if they do it's a shockingly well-kept secret)

@@nowandaround312 I think it was a joke.

Octy lady???!!!!

Return to jelly

Is squishy one or many? We do not know. Might be a collective Something in between a colony and a whole! So you can be a gonad A mouth Or perhaps the part that has to give them transport around the ocean Or the bodyguard of stingers

Its an interesting question perhaps one interesting bit of information is that not all cnidarians possess a Medusae stage in particular the Anthozoans(true corals and anemones) lack medusae whatsoever reproducing sexually as polyps instead. So the medusae probably came later with anthozoans having instead evolved bilateral symmetry in their planulae stage to allow their larvae to feed as planula and seek out more distant and potentially more ideal spots to attach themselves and mature into polyps. That said it is not uncommon for eukaryotic organisms to have separate asexual and sexual reproduction strategies in fact there isn't much of a distinction between somatic cell replication and asexual reproduction other than that the new cells separate completely. Asexual reproduction tends to lead to the accumulation of harmful mutations as does life well living in a messy environment with radiation viruses etc.. However due to these mutations being largely random nature(barring protected sections of the genome which are more guarded against mutations due to them being much more important) they can be largely fixed by sexual reproduction as it is extremely improbable for the mistakes to be in the same positions hence why both might be advantageous. This doesn't answer where sexual reproduction or its unicellular counterpart conjugation came from however. The origin of meiosis can be naturally explained under the viral Eukaryogenesis hypothesis which notes the shared morphological structure of a Eukaryotic nucleolus and the viral replication factories of Nucleocytoplasmic Linear/Large DNA Viruses and the shared genetic ancestry of this family of viruses and the conserved core of Eukaryotic genomes which has been shown to predate the Last Eukaryotic Common Ancestor by molecular clock estimation. This given Eukaryotes featuring the decoupled translation from transcription seen in all viruses during their "living virocell stage which works in a fundamentally different manner from the coupled transcription and translation seen in all bacteria and archaea studied thus far and it looks increasingly probable that meiosis aka sex is a modified form of viral recombination which is used by many viruses as both an important form of error correction but also a potent way to undergo rapid mutations quickly.

Yes that is correct

Identical medusas= the separate functioning 'organs' But the medusas only make the initial factory But do we we since we can fertilize or produce an egg but in the end the egg divides itself into separate functioning cells it is just that a hydrazone instead of dividing in cells these are classed as separate organisms. So where is the dividing line between a vertebrates cell divisions and polyps specialised asexual reproduction in the way that animal cell division is a bit like asexual reproduction.

Given that some kinds of Cniderians are functionally immortal, if not Squishy Prime, then certainly one, or more of his clones will be pulsing away in a sunny area of the tank, somewhere.

I mean technically that's in the microcosmos too. It's just two cells plus a complicated life support system 😉

Came here to post exactly that 🐟

Same!

Sus!

Those are scale bars to give an estimate of the size of the specimens you are viewing. For this type of microscope, they are usually in micrometers (μm), where the Greek letter "μ" (mu) means micro and "m" stands for meter. One micrometer = 1/1,000,000 of a meter, or 1/1,000 of a millimeter.

@@rustyshackleford9888 thank you very much! You explained that well.

gonads are a general term for sexual organs it doesn't say if they're ovaries or testes
