Phylum Mollusca Part 2: Class Gastropoda (Slugs and Snails)

With an overview of phylum Mollusca complete, let's dive into the classes within this phylum, starting with the most diverse, Gastropoda. This one contains familiar creatures like snails and slugs, as well as lesser known organisms like limpets, abalones, whelks, conchs, periwinkles, sea slugs, sea hares, nudibranchs, sea butterflies, and sea angles. Some of these look amazing! And they live in a wide variety of habitats, from marine to freshwater to land. Let's get a closer look, shall we?

I love how Dave keeps it straight when he talks about some of the more "interesting" parts. Nice job Dave on the whole series, it's very informative and well presented!

[@lostfan5054]

I love these episodes, Dave. I gotta set aside time to binge the entire Prof Dave catalogue!

[@connyespersen3017]

@ProfessorDaveExplains Professor Dave!, I have to thank you for your fantastic, seriously, informative and interesting videoes. They are doing my life and my days much better! The way you are treating science insights and are explaining it, using word and not to many terms, so it's easy to understand for everybody, who don't have a degree in science. I love how you treat - what by the first sigth seems like - triviel cases and the most popular, complex, deep cases as equal with the same weight of importance. I think that's exactly how we in reality should reach out for insights and better understanding of how, all in our world is build up and how it's depending on so many other aspects. How we are seing (sensing, measuring) and interpreting what we are seing trying to understand the behaviour of the reality! I realy like your videos and think they are among the all times best science videoes on KZbin. If I doubt about a scientific question, I only have to find a video made by you about that specific question. Then i know I will be educated about it in a truthworthy way. Happy to live in a world where PEOPLE LIKE YOU shares their knowledge in such a proper way - like you - to a good part of humanity. Of course I can't know exactly, why you are doing it, but that really doesn't matter for me, if you - and other of the same mind as you - will continue doing this sharing. I believe in what you are doing and in nearly everything, you are educating about. I surely got a critic sense, which I always am using, but I have never caugth you educated something there is very wrong. I my eyes, you look like a very trustworthy person with a GREAT SCIENTIFIC KNOWLEDGE. Again - here reaching the end of my commentar - I want to THANK 🙏 YOU much more than one thousand times for your efforts in making these wonderful YT videos.

0:33 Nudibranchs, sea hares, sea angels, and sea butterflies are all subcategories of sea slugs, not separate. 0:36 Fun fact: the nudibranch depicted has cerata rather than the branchial plume nudibranchs are named after (lit. 'naked gill'). A nudibranch with a branchial plume is shown instead at 0:33. Love your videos, Dave!

Was going down KZbin SNAIL hole! And stumbled upon this nice shell of a video. Thanks yo!!! God bless n b safe.

[@jetcitykitty]

Awww, brother slug! Slugs and snails are delightfully cute. Cutest "bugs" imo

[@jetcitykitty]

Creatures that people would avoid but produce structures those people see as gifts...you have a good heart, Dave ❤️

[@wiktorutracki6469]

12:40 this might just be the craziest thing I've heard in a long time 😂

[@WarrenSapir]

Very entertaining and educational. Thank you so much for sharing your knowledge. I greatly appreciate learning new and interesting things!

[@sciencenerd7639]

wow! thanks for doing this series, it is my favorite.

[@binteaziz2054]

Your lectures help me a lot to understand my MDCAT stuff!

Well, that image isn’t going to leave my mind for a few days. Great video!

[@grimcity]

Thanks for taking the time to make these, Prof... our alien-like little cousins are absolutely fascinating to me. Cheers, good sir!

[@Mothobius]

6:45 I don't think those are freshwater snails. Aquatic snails usually don't have eye stalks like that... Maybe I'm dumb but they look like land snails

[@Graeme_Lastname]

Fascinating and unique.

[@ExplosiveBrohoof]

I'm eagerly looking forward to the video covering monoplacophora. I'm curating a playlist that covers marine biology, and there are zero good videos on this class on KZbin.

[@JackReed897]

hell yea i love binge watching snail videos,,, :'D

[@binteaziz2054]

I'm waiting for other parts!!!! When will they be available?

[@petrfedor1851]

Wonder how many times gatropods reduced their shells.

[@amitsinghbhadoriya6318]

Thanks

[@Projacked1]

Wow, my mind just blew up a bit up. Fascinating!

[@TundeEszlari]

Amazing video.

[@kyleericludwig]

found this video a bit sluggish tbh

[@AlbertaGeek]

I'm too just-woke-up to appreciate that pun right now. Will upvote later.

[@StoryTellerOfficially]

Sir , can you divide them into chordates and non chordates? Like in the form of vertebrates and invertebrates

[@ProfessorDaveExplains]

Chordata is a single phylum. So all other phyla are nonchordates.

[@StoryTellerOfficially]

@@ProfessorDaveExplains no sir I didn't mean that I mean to say all vertebrates and invertebrates can you make them in two videos like, non chordates from protozoa to till platyhelminthes I am trying to say that, which a phylum comes under non chordates a separate video and which all phylum falls under chordates a separate video.

[@ProfessorDaveExplains]

@@StoryTellerOfficially Chordata is a single phylum, and vertebrata is a subphylum within chordata. All other phyla are nonchordates and therefore invertebrates. I won't get to chordata for quite some time at the end of the series and it will require dozens of tutorials. I don't know how to be any clearer than this.

[@zrttatertot4528]

of all the questions i had on the topic, only 1 remains unanswered. What is your favorite snail Dave?

[@judeboys6409]

Horse conch. I got your horse conch right here 😂.

Giant Horse Conchs? I thought Vaush was the internet expert?

At 6:40 you misidentify a giant African land snail as a 'common freshwater snail'

What weird informations presented 😳 Elaborate colorful penises that rise from the head, stabbing ritual and what a deserving name for volcano snails. I am also confused whenever a new species or genus is named using Latin (i mean who still uses Latin and speak it fluently to name new things using it) ?!

[@trashAndNoStar]

Latin naming is standard convention so everyone from all around the world can refer to the same thing regardless of their own language & regional vocabularies.

[@waelfadlallah8939]

I did not know that Conch was pronounced “Konk” I thought it was “Konsh” or “Kontch”

It's pronounced "kontsh" in British English but "konk" in American English
