Rotifers under the microscope
Вставка

- Rotifers are microscopic animals found in aquatic environments all around the world. The name Rotifer comes the Latin words "wheel bearers" for the crown of cilia on their head, called the corona. The cilia on the corona beat to create a vortex that draws in food for the rotifer to eat, which consist of dead organic matter, algae, protozoa and organisms small enough to fit in its mouth. In some species, The corona can also be used to propel the rotifer forward and help it swim.

They are microscopic, but in many ways very advanced multicellular organisms.
Neato! When I was a child, I saw little, foggy orbs in the lake water, so I placed one under the beginners' microscope. Instead of being a true sphere, it was a 3D star made out of many elongated objects connected in the center. To my amazement, one of these many "cigars" would break free, swim away, and be replaced by another that would swim up and fill the gap in the star/group. They were rotifers doing some rare thing I only caught twice, connecting up like this (mating?). My biology teacher identified them and was delighted to have be bring two large pickle jars of them in to share, look at, and keep alive for a bit until releasing them again. They're quite hearty.
I thinks thats them making a coloney

Rotifers are microscopic vacuums
Man that last clip was incredible, to see those vortex’s the rotifer generates 😍. Subbed!
Thank you!
your videos are always so calming and help me remember that theres more to life than day to day problems
Very good work! I've seen some rotifers also, but they were not moving like that. Been busy looking for tardigrades, but came across a few apparent rotifers. Now I have to find one like yours!
Martina Vaslovik I have been trying to decide what these things are! Also doing tardigrade research... don’t understand how they are in my licen samples 🤔
From where to find tardigrade
@@anilkumarprajapati...1260 Right after a good rainfall, find a puddle with some mud or silt at the bottom. Even a shallow puddle on a sidewalk with a thin layer of dirt at the bottom, or between cracks, might work. Gently drag a pipette along the mud, sucking up a few swaths. You should get some good tardigrade specimens in there. :3
@@anilkumarprajapati...1260 Usually moss or wherever you can find small amounts of water. I found both rotifers and tardigrades from a small puddle that formed just outside my house a few hours after it had rained. The rotifers inched about until I supplied them with enough water in the pipette, and they would go searching. The water bears clung to large mounds of dirt and clusters.
I found my first Rotifer tonight! this is my favorite video showing off the amazing feeding mechanisms.
Awesome. Where did you find it?
I was actually hunting for tardigrades. I soaked some moss samples from the backyard with sterile water. then hours later took a sample with a syringe, and there it was. At first it was covered under some moss so it looked like the moss was moving and I was just fixed on that waiting to see. When it started feeding and the cilia started spinning I was in disbelief that I was fortunate enough to find a rotifer, I couldn't believe it! It's feeding mechanism is so amazing to see with your own eyes and it's my favorite microscopic multicellular animal so far. Luckily I ran and got to share it with my 6 yr old son and my wife. So far we've seen gastrotrichs, parameciums, now a rotifer. I'm hoping to see the water bear next!
Awesome. It is very exciting to see these guys with your own eyes for the very first time. Sampling different areas, river, ponds etc. you can find many new different organisms. It is a very fun hobby. Keep looking and you will find some amazing creatures!
Yes and it's even better when you can share it with others ie children, friends, youtube subscribers, lol. It's a great way to get your kid interested in science. I've tried to foster that appreciation to the natural world for my son. The day after seeing our first animal the gastrotrich, he said to me, Daddy, remember yesterday when we looked through the microscope and saw a whole new world? Lol priceless
Wow that is amazing. Glad to hear you are inspiring your son. It truly is a whole new world. I agree with you, its better to share, that is why I made a UA-cam channel lol.
When they move they look like worms moving
At first sight I thought that was an astrounout
you were prob high
Kent Wilson if he was high then I was high
And i thought it was a robot 😂
Same here
Me too
Very well done video to show their anatomy and relative size, as well as how they "eat." I had never heard of or seen these creatures until I recently took a sample of lake water under a microscope and filmed some myself, then set about to researching them to discover their name and habits. That research also brought me to your video, which does a great job of demonstrating their characteristics. I appreciate your posting it.
Some very nice shots of a Mastax there! Lovely rotiferology!...
Your videos are the best
Nice video and captions
Now picture it 10 feet tall, staring you in the face.
You're welcome.
Thanks a lot!
Learnt a lot (as compared to school practicals 😂)
Great video, thanks.
Good job!!
Congratulations on your video.
Very clear, music not too overpowering, very useful captions.
My microscope was not in the same league and I sold it on.
If I didn't have floaters in my eyes I would replace it but they get in the way.
So videos like yours are a better option for me.
I was surprised at how quickly Bdellids? move around when I was viewing them.
They would shoot out of view quite quickly..
It didn't seem to me that the moving cilliae could provide that level of acceleration.
So I thought it must be jet type propulsion through the anus.
But it seems this is not possible.
Very interesting beasties.
Thank you Ronald. I believe they swim using their cilia, it is quite amazing.
Nice video
soooo amazing! love this.
Snap?
Oh my gosh, do you have any proales reinhardti footage? Their my favorite animal.
Sorry, I don't unfortunately.
fanstastic, very clean and nicely presented👌👌👌👌👌👌👌👌👌👌, thank you so much
Amazing 😯
I love the song!
Ive seen Rotifers under my microscope and trust me, they look fantastic.
Also known as wheel animals, rotifers are common in rivers, lakes, puddles and gutters. They are among the smallest animals that exist. Rotifers feed on protozoans and other tiny lifeforms, which they catch by beating a crown of cilia to draw water into their mouths. In dry times, rotifers are dormant. Once in this state they can stay inactive for many years.
That's just really cool
Did you make the music? Good job
What’s the music for this called? It’s so relaxing!
Love everything about this video. Question, what is the rotifer's "foot" apparently sticking to so the head can move around?
It this video, the rotifers attached themselves to the base of the glass slide or to the clumps of algae and other cells. Basically anything they can get a hold of.
+Sci- Inspi cool, thanks!
also, how does the microscope move around to keep the subject in view? What feature is that, or what is it called?
I manually move the microscope stage to keep the specimen in view. It is difficult sometimes but you can get footage of things swimming this way.
+Sci- Inspi thanks! great, now I have to buy a better microscope! lol
Your welcome Michael. I need one too, lol. Happy microbe hunting!
They create a vortex to suck their food!! Like me! What an amazing video!!!
Awesome video, why do your specimens look so much bigger than mine when i set my microscope to the same magnification? Some of your images at 400x nearly half fill the frame whilst mine on a 40x objective and 10x eyepieces looks much smaller?
Rotifers come in different sizes, so that might be one reason. Another reason may be that I might get some magnification from the camera itself since I don't use an adapter.
The music for this could not be more perfect
that was so cool!
What specific microscope was used for this
How large are Rotifer cells? I observed that human cells taken from the inside of the mouth are around 1/2 the size of a single rotifer; sometimes 2/3 the size (depending upon the rotifer species)
I am not sure, but they are pretty small.
Thumbnail should be titled "To infinity, and beyond!"
Its amazing
Nice. I find so many of them living in my gutter!
excellent video pls let me know microscope model with camera details
Camera - Nikon D3300
Wards trinocular Microscope (not sure the model) - 40X, 100X, 400X, 1000X
American Optical One - Ten microscope - 150X, 600X, 1500X
Hope this helps.
Look at its little trophi go!
I found one while looking for water bears. I was feeling very guilty when I killed him 😔
so cute
What are three parts of a rotifer?
Omg! So clear
Is it weird that I find it adorable?
Nyeope
I liked the music...
Can you post the name of all the songs used in your videos?
I make all the music for my videos. Those interested in my music will be able to buy my music soon.
Sci- Inspi
Nice.
Your music is awesome!!!!!!!!!! I love it... i just wish I had the money to support you.
Thank you. just enjoying my videos is more than enough support.
so the puslating bit in the middle is the mastax?
Correct. It is used to chew their food.
Was the music one of the later incarnations of Tubular Bells by Mike Oldfield?
Hi Adam,
I made this song by just noodling on my guitar.
Btw, I looked up Tubular Bells, that's the exorcist song! It is an amazing piece. Thank you for sharing such a great musical piece
Wow. Good job. I have Tubular Bells I and II, but I know there are several later iterations. Parts of your soundtrack sound like specific passages on the original Tubular Bells, so I had to ask. I don't mean to accuse. Music has no end.
Yes, it's the Exorcist song. It's also a really entertaining album. BONUS: It was the first album signed under the Virgin label.
I didn't take it as an accusation, but as a complement after I heard Tubular Bells. So thank you. There are only so many chords and scales, some songs are going to like others. Also I didn't know that it was the first album signed by Virgin. I learned a lot from this post. Thanks again for introducing me to some great music.
Corona!!!
they are cute
The water bear!

Wow
Corona 😃
Look at Rotifera, here:

I have different type of rotifier which eats small ciliates.
Rotifers with a machinery vacuum mouth.
😮
I should call her
This are fixed multicellular organism
Fun fact : stentors can be seen with a naked eye They Look like Dots!
1:27 that unfortunately named haha
CORONA HAHAVIRUS
I thought that it itself was making that sound 00:01
Is looking like Anomg Us
drrrrrrrrrrrrrrrrr i am meanie
Death Note music much?
Rotifiers are sharks
Türk-is speak(Insana benziyor)
what this video shows?
Biol2003
Where is its heart, ,??alive with no heart
They don't need one. They are small enough to have diffusion circulate nutrients sufficiently.
Sci- Inspi no brain?
T
Gotta play stupid music...click out!!!!
The Glory of God :)
I cannot watch a video about a Rotifer (or any other multicellular microscopic animal) and Not think that! And to think we've only known about this world a few hundred years!
Sorry but there isn't any god
Matteo Carta+ If you think there's no Higher Power of some sort, that all life in the universe and possibly beyond, came about by chance, then you have a very closed mind.
Will Scarlett no, you bigots have a really closed mind
Matteo Carta+ If *you* weren't a bigot or an ignoramus, you'd be open to quite a few possibilities.
