Phylum Mollusca Part 1: General Introduction
Рет қаралды 41,054
Жыл бұрынWe'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)).

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

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.

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.

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..."

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!

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 prefer octopodes or octopods because it is a Greek word and in Greek the singular is χταπόδι and plural is χταπόδια.
