Sea Star Anatomy Part 2

("Part 1: external anatomy and dissection procedures" can be found here: • Sea Star Anatomy Part 1 )
Internal anatomy of a sea star. Phylum Echinodermata, Class Asteroidea.
This video was made by the teaching assistant (C. Ernst) for the students of Organisms II at McGill University, but is appropriate for any introductory-level zoology program.

Thank you so much! The year is 2021, I am from a Government-funded university (lesser funds and opportunities to have labs like these) but you have done great help so far! Thank you so much! God bless you!

[@TheCodyWalker]

Hey thank you very much. I have a biology lab practical exam over echinoderms, mollusks, arthropoda, and chordata, and I'm sure I will have to identify something on Echinoderm anatomy. This helped me study!

Every time I watch one of these amazing videos the comment section is filled with complaints about the lack of gloves. Why waste gloves when you don't have to? Most of the animals are preserved in alcohol so calm down people.

[@shanedoe3462]

Agreed. Also, why does everyone comment on the way she pronounces "mouth"? I don't hear any accent or regional dialect whatsoever. It sounds the same way I've ever heard anyone else on t.v. or in the movies pronounce it.

[@PencilGonzo]

Your voice is so soothing. I want to record it and play it right before I fall asleep.

[@smittymusicrocks]

You have the best dissection videos! Thanks for helping me study for my lab dissection quiz!

[@annypr4]

I love all your videos. You and they helped me so much in my studies, thank you so much.

[@rookolas]

Best video I've found! Thank-you very much....this helps me very, much since I did not participate in my classes dissection.

I admire the functioning simplicity of this organism.

[@aanapur2859]

This video from 8 years back helped me a lot And your explanation was really good ♡ Thank you ^_^

[@sheaaaaaaaaaa]

thank you, this really helped me for reviewing for my practical tomorrow!

[@OsCassador]

star fish and sea annenomes amaze me, they somehow know when to eat, though they dont have a brain... all nervous system

[@daniepatchell3460]

My husband and I were discussing sea star reproduction and I came across this awesome video! I went to Guelph but this makes me wish I'd gone to McGill :)

[@jimprescott4955]

Top shelf dissection. Great!

[@oopsgingermoment]

Lab practical tomorrow. Thank you sooooo much!

[@candleflame4355]

In soviet Russia starfish dissects you. rawr.

There needs to be a drinking game. Every time she says "mmkay?" take a shot.

[@kukukk13]

Cool! Very informative I learned a lot

[@ojkolsrud1]

This makes me a bit queezy! However, the video is excellent, and I learnt a lot! Thanks for that!

[@Nekochi90]

I want to scrape out those suction cups. Don't know why, but I just want to.

Nice video

[@gabebraet9442]

Why no gloves?

[@VivaLaKaatiee]

Who wants to see if Pyloric Caeca would be a good sandwich spread?

[@markgoldwater1250]

Cool

[@tiamelancholyjeoncockity]

Oh poor Patrick...

[@tiamelancholyjeoncockity]

Hopefully Jotaro never sees this 🤭💀

[@cringle5]

[@TheMinDe1993]

[@nanatsukihaq3252]

So helpful!! Your explaination just so great! Now I know about see star!! Thank you so much!! But I'm still feel so sorry to Mr. sea star...

[@ysjrrodriguez4171]

That looks so yucky but eny way pls wear gloves i did that but i wore some gloves teehee

[@koolaid5684]

hehe....she said gonads...

[@devinkan727]

The green look like poop

[@vanessajara1848]

Poor seastar

[@princesssorathepoof]

Shouldn't you be wearing gloves?

[@tjhall1000]

poor starfish didnt deserve death v__v this is why aliens wont talk to us, cuz we like to dissect anything that lives.

[@konradstrich1822]

We wouldn't have made the advancements we have over the years w/o conducting these experiments. It's thanks to these advancements that we're able to have new kinds of medicine or procedures done, increasing our survival rate and also finding new and better survival rates for these kind of organisms.

[@tjhall1000]

your talking about legit science, this is petty internet video science it means nothing and it kills animals for no reason other then to make a video. real science is fine. we gain from it exactly like you said. but this was not real science

[@jessiesflowers2841]

tjhall1000 I agree I don't think the starfish deserved that ether

[@Datan0de]

@@tjhall1000 Your heart is in the right place, but I disagree. It's educational. Not all zoology can be learned by reading a text. Of course it's unfortunate that this sea star died, but how many marine conservationists can learn from a single video? I'm not a scientist, but found this video simply because I was curious about starfish anatomy. I think there's value in educating the general public as well.

[@sethkeana1835]

@@Datan0de Yo bruh, they will die anyway. I want do dissections as little as the next person, but we may as well use their manifestation of inevitability for some purpose ay...
