Phylum Annelida Part 3: Oligochaeta and Hirudinea (Segmented Terrestrial/Aquatic Worms and Leeches)

With the marine segmented worms covered, let's get a closer look at Oligochaeta and Hirudinea, which include the familiar earthworms, and the leeches. The anatomy and physiology of the common earthworm is actually quite fascinating, press play and see what I mean!

Throttle me with your worm knowledge

[@uncleanunicorn4571]

They were the subject of darwin's last book.

I literally have an exam, and I have to memorize these 2 classes… this just popped up on my homepage.. matrix confirmed.

[@momoirorabbit5137]

The same😅

[@objective_psychology]

I'm so happy you're doing some more phylogeny, especially now that I'm getting more interested in biology

[@imagomonkei]

This video is so fascinating. I've never thought that earthworms weren't alive, but I've never thought about them in terms of their own motivations. It's really interesting hearing you describe them needing to find their burrows after the rain has passed. And thinking about them. Having some kind of motivations that aren't simply robotic processes is very intriguing.

Glad to see Dave posting his regular content again

Darwin's last book was on earthworms, A worthwhile subject. I am contracting my pharynx with excitement.

Thank you Dave for this great educational video !

[@Naomi.Robertson]

They also make good bait when fishing. Thank you for the video very interesting

Choosing Professor Dave over my lecturer at this point❤❤❤❤❤

[@egechicken]

I had to dissect a lumbricus terrestris. It was gross to touch and hard to cut open because its so slimey and small. Still had fun at my course tho. Thanks for freshing up my mind on this topic.

[@gugulethundlumbini120]

thx Prof Dave

[@sciencenerd7639]

this is great, thank you

[@timsullivan4566]

Excellent content - answered numerous nagging questions. (Oh dear, "worm" my manners? Thank you, Dave! 😉)

[@sanjaikumartiwari8275]

Hello Professor, How you have this much knowledge and you Remember it all? Do you revise things on a regular basis? Please tell me It could help me a lot. Also Sorry If I caused any Disturbance or Distraction. But Please Reply How you do this.

[@RevilHermes]

What a strange and fascinating thing.

Do you think you'll eventually make separate playlists for entomology and for vertebrate zoology? Since I'm pretty sure a vast majority of zoologists are either entomologists or specialize in some group of vertebrates, there's probably a lot more to talk about with phymum Arthropoda and phylum Chordata than with any of the other phyla.

[@ProfessorDaveExplains]

i'm just throwing it all in one!

[@gormanls]

More phyla day is a helpful day for me

[@NUCLEUSACADEMY-fm3cc]

hey dave can you please make a video on pam reynolds case

[@_ninthRing_]

No doubt medical staff are pretty emphatic about counting all the leeches after certain procedures - otherwise you may just end up with a suspiciously frequent number of nosebleeds after nose surgery... : /

Our mouth, throat, stomach, intestines, & anus are essentially like a worm, our ancestor?

I knew it, episode 3 was gonna have worms…

Enjoy your vids as always! Any chance you could take on the people who dont believe in global warming next? I just got into the dumbest argument, and im just honestly not as good at debate as you are, or with words in general lol

You should tho the phyllum Echinodermata!!! I had a presentatión about it, a tutorial about them from you would've helped me a lot 🫶
