Phylum Mollusca Part 1: General Introduction
HTML-код
- Опубликовано: 4 июн 2023
- We've covered most of Spiralia, but now it's time to dive into the final subclade, Lophotrochozoa. This contains several phyla, the most diverse of which is Mollusca. This phylum includes snails, slugs, octopuses, squids, oysters, scallops, and so many other familiar animals. Let's get a general breakdown of the phylum first, and then we will go into each class in more detail.

Yoooo!! When i was at uni one of my teachers was a malacologist and had a snail species named after him, he was so inssufrable, Who would have thought that a man interested in snails would turned out to be not a gentle soul but a vicious demon
his argument on gender was so poorly made. just as much as Chinese cannot insist that I'm white, XY chromosome person cannot insist I'm female (I'm not talking about a case of gender dysphoria with XXY). also if you're only born as a male, how do you know you're female without never having experienced as female? it's like insisting I'm Martin Luther King because I feel like. what do you mean by that? how can you feel like some other identity without ever expericing the identity?
gender identity is based off of majorly clear binary patterns of sex chromosome. neurochemical expression governed by those chromosomes are within it's bimodal patterns largely because the expression of chromosomes heavily set by preexisting condition whether XX or XY (again not including the exceptional cases with abnormalities (X or XXY, don't mix them up)).
@@JC-sn2hx sorry, o cannot see the connection to my comment. Are you talking about my teacher?
@@deiniou sorry I just wanted to deliver this message to the RUclipsr. It wasn’t relevant to your comment.

@@JC-sn2hxbro what ? 😂
Just a random Indian high school student here....dude the quality of your content, the vast topics covered, your nature, everything is just so good❤️ You're really soo underrated. Currently I'm watching your astrophysics series, as it's my area of interest & I want to make my career in this field. I hope one day I'll get this type of scientific understanding you have (or even more😼), & also get to meet you once in my life. Thank you for your work!
One more thing
Since you know a lot about the science stuff, I wanted to ask, what are some hot topics in research in physics so that I lean towards them in building my career? I love astrophysics but if there's something groundbreaking which needs right now, I might as well try to pursue it
Dude. I didn't know you had a classification of life series like Aron. Looks like I know what I'm watching for the next couple of days.
I'm totally getting Darwin's hand drawn clade as a tattoo.
He got a lot of science series. More than 410 videos on chemistry (that was what he started with)
AronRa's legendary _Systematic Classification of Life_ series had a bit of a different thrust, though. He "started form the beginning", as it were, and ended each video with the next evolutionary step towards humanity.
@@AlbertaGeek I really love AronRa's series. I learned biology in the stone age (before DNA tech was around).
The only change since then is adjudgement of the Tree Of Fife.
I learned that mushrooms were plant -false
I learned that tower sailer were swallows - false
An a small numbers of misc errors.
However 'Evolution by natural selection' persists unchalleged.
The most devastating question to expose an atheist is:
"What is the airspeed velocity of an unladen swallow"
I’m enjoying the series and appreciate your work.
Thank you so much, Prof. Dave!!!
This is a good video for reviewing. Currently studying molluscs and echinoderms
Thanks, Dave........might ad, some of the most powerful venom, microgram for microgram, is found in these lovely creatures. Can't wait for more.
even when just going through classes of organisms it almost resembles a path of complexity. just looking at the bigger picture and you can see evolution in action! nature is amazing!
💙 i have a deep love for octopi and snails, octopi for their incredible independent evolution and intelligence, and snails for being adorable
Me too!
I actually liked this phylum so much and some of the footage are mesmerizing 😊
Sir please make videos on phylum.....I'm addicted to your videos...
I checked my notifications and it was up less than a minute ago :D
I have divine intellect
I'm a little confused on a specific issue of general characteristics: the trochophore larva is a general character but not unique in this group. In college I learned that the most important larva is the Veliger larva, so I think it is important to mention it in the video because the Trocophore larva is found in other groups of invertebrates, but Veliger is unique among mollusks.
Snails and slugs have to be one of my favorite things on this planet. They're so cute 🥺
they poop on their own head... nearly ualiving them selves
@@marcussg0813Stop, he is chinese
Hi. your content has been incredible help, is there anyway you could please post more videos explain this phylum and more on to the next phyla. THANK YOU.
Oh no, I've binged the series and have nothing to watch.
I'd imagine that Mollusca is going to be a huge one seeing as they're such a diverse phylum. Makes you think about what if the tree of animal life actually split off, and those cephalopods are on the same distance from the trunk as we are on our branch. Can't wait to see more. Out of curiosity though, what were the two hidden videos?
Also, once this tree is exhausted, will we delve deeper into Chordata? I would love to see an in-depth look at how different offshoots appeared, and how mammals eventually became the dominant class and how birds, reptiles and amphibians got as diverse as they are today.
Thanks for the awesome videos!
there's several more mollusca, i'm a bit behind in producing these, there'll be a ton more
I love your channel. Thank you for all you do.
The most well-known of all spiralians!
Cover the flappazoids next pls
Brilliant and informative video, keep it up. 😉
Fascinating. Thanks P Dave!
A snail and a slug crawling along, not watching where they are going, and they have a head-on collision. The police come to investigate. They ask the snail "Can you remember any important details about the accident?" The snail says "I dunno, officer. It all happened so fast..."
This is very interesting. They aren't so fun when they squirm under your patio door and onto your carpet to be stepped on in bare feet but they are still interesting.
You forgot one last member of the Mollusca phylum: The Commuter Slug.
The Commuter Slug is vastly different from the other classes in the Mollusca phylum. The Commuter Slug is most often bipedal and stands upright, though it spends a good deal of its time sitting around on its "foot" during the work-day. They can most often be found early in the morning, standing around in large parking lots located several miles outside the beltways of most heavily populated urban areas. They are best known for waving down unsuspecting vehicles and begging for free rides in exchange for the driver of the vehicle being able to use the HOV lanes. Commuter Slugs eat almost anything, but are decidedly partial to large volumes of caffeinated beverages, especially in the early morning. There are exceptions, but Commuter Slugs tend to make poor conversationalists and generally prefer to keep to themselves until they get to work.
I thought this was gonna be a little kids show but not so much ❤
I think snails are sooo cute!!! 🐌
Im sure someone has mentioned this already, but isnt the plural of octopus octopi?
Either is acceptable but apparently experts prefer octopuses!
I prefer octopodes or octopods because it is a Greek word and in Greek the singular is χταπόδι and plural is χταπόδια.
In his house at R'lyeh...dead Cthulhu waits mollusc'ing.
Wow mollusks have all the eye types covered (ok not all)
Octopi
I think the habitat for leopard slugs is just hiding under stuff in my back yard
Their habitat is yes
Hey peeps
Hah, you said "pee" :D
Yo. ✌🏾✌🏾
You were faster than me this time, i was preparing to call out your name 😅
@@waelfadlallah8939 how are you, my friend?

What average people call 'sea shells'
...Often sold by the sea shore. Let's hear it for Mary Anning!
I’m allergic to this video😢
Get ready for another one next week
octipi....lol
Firsd
Doesn't count since you wrote it wrong 😂
Better luck next time

Can’t wait for this one to be out this got be my favorite Playlist it really is sad that we will destroy the planet and all life will be extinct...
Professor dave is sort of arrogant, maybe he is at the top of the Dunning-Kruger effect, so probably iq 129
I’m pretty sure you don’t know what any of those words mean.
@@ProfessorDaveExplains haha i made that comment on purpose to trigger you
@@ProfessorDaveExplains of course theres still irony in the fact u dismiss what i say instantly
