Phylum Platyhelminthes Part 2: Free-Living Flatworms and the Problem With Turbellaria

- With the basics regarding phylum Platyhelminthes covered, it's time to start digging into the clades within. Free-living flatworms were originally classified within the class Turbellaria. But more recently the clades needed to be rearranged, so instead this tutorial will focus on members of Rhabditophora. Specifically within, we will focus on clades Polycladida and Tricladida. This includes the well-known planarians like Dugesia. What do we know about these species? Let's find out!

Nice.
You might want to work on your english there. Just a little bit.
@@dotsdot5608 who's saying he's not? I mean I bet he knows where's he at, and I understood perfectly.
Im learning about helmints this semester, thank you for covering so many topics!
I’ve just learnt that your a professional musician, had a record contract etc but it didn’t quite work out, nearly famous but not quite . Now your famous selling science . You’ve been on the same journey as Brian Cox , he was a keyboard player in a band that didn’t really make it, then he turned to science to become famous, what an amazing coincidence
.
thank you! wanna say these videos are great!!! and they help me so much in my zoology, bio, and chem classes!! im also a trans student and wanted to thank you for calling out people like matt malsh!!
I just realized I'm listening to the same Gentleman that calls out stupid ass flat earthers. Bravo sir I love Reef keeping and ocean life. Very informative.
Your videos made me interested in science, and I'm glad I am, good job on your videos.
I love how Derpy these guys look
This series is quite good
In my opinion, worms are the most boring animals, because most animal phyla are worms
Another fun fact about terrestrial flatworms is that theyre adorable. Some have googly eyes!
Very cool. I’m really enjoying this series.
Related question on the planarians and the 279 separate part regrowth... if those 279 organisms were each cut into 279 parts themselves, I imagine they'd also grow into 279 new animals each, but I wonder if we'd start to see problems in the new generation related to any kinds of exhaustion in the stem cell lineage? If the problems didn't occur by the 3rd or 4th generation, would we see something around the 10th or 20th? (given adequate nutrition, etc.)
Happy diwali sir... from India
Great video, thanks
another great video!
Some flat worms have such cute goofy eyes
Damn, who knew flatworms were that kinky
10qqqq sooooooo much for your lectures
I always found hammerhead worms fascinating 👍
Bilateral transfer is my favorite genre
Dave, Could you discredit douglas vogt, he is saying that the sun novates every 12,068 years
I am assuming that the cells (or some) are or become totipotent or pluripotent in order to produce a whole new animal. Presumably the Hox genes work in the same way as in the embryo to attain the 'nose to tail' developement?? Does anyone know? I am also reminded of complete metamorphosis where the larval form disintegrates in order to make way for the adult phase. Does the Hox system re-activate in these cases or even 1 case??
It's always nice to hear someone smart, and for some it may be boring, but I'm finding it as fascinating as aliens.
DOPE video. Thanks yo
From the ice-age to the dole-age
There is but one concern
I have just discovered
Some worms are bigger than others
Some worms are bigger than others
Some worms mothers are bigger than other worms father / mothers
Keep going ♥️♥️♥️

Good day sir can we be friends,I like your teaching I will like you to be my Tutor. I'm a student of Animal and environmental biology
Helo
Damn that worm is flat af
