Bdelloid Rotifers Going About Rotifer Business

A composite of 3 short videos I made of a button of centrifuged microbes. These came off a small sample of Hornwort leaves from my aquarium that I spun down in my minifuge.
You never know what your going to get, but it's always interesting. Enjoy. :o)

Wiki brought me here. "I love watching rotifers." And for some reason I understand because it's mesmerizing.

@PondWaterWorld The secret is the centrifuge. It concentrates them all into a small button at the tip of the centrifuge tube where you can just suck them all up in a pipette. :o)

Nope, their rotors for sure do not spin. They are simple cilia, which you can see clearly if you use flash photography in the scope and take high shutter speed still. I've done it. :o) Flagella are just long cilia, and they move by the bug using chemical stimulators on the base of the cilia, analguous to the "follicle" on a hair. Rotifer cilia are not the same as say a paramecia or bacteria cilia. One is a single celled animal, rotifers have 1000 cells. Big difference.

@Znobyrd Hi Larry. Early on, I bought a plastic slide box with 100 slots. It has a nice locking lid and cost about $6. I have 10 drpression slides, about 10 plain smooth slides, and the rest are plain slides that I put 4 dots of nail polish in the 4 corners a coverslip would sit on. After they dry, they lose some of their height, but are still high enough to not squish everything but copapods. I use the depressed slides for those. I even have some of those with the 4 dots, for added clearence.

@Znobyrd That's what's so amazing about this hobby, you see something and then may never see another one. Rotifers are pretty common, but it's months since I have seen any parameciums or stentor, and they use to be pretty common. I am sure it is water quality, they require fresher water than whats in my tank now.

I was initially grossed out when I first discovered rotifers under my microscope. I was looking for tardigrades. However, I've come to love the rotifers. They are really cool creatures.

How did they communicate before the "Cell" Phone? We should all know they "Rote"(Rotifer = Rote) back and forth. And they probably still do because they know what's best.

Darn, you make some nice videos. That little guy at 4:00 you said looked like a hot air baloon... I saw one yesterday, I called it a chopped - off bowling pin. Not sure what it's called either.

Those hornwort leaves have more than their share of Rotaria, Philodina. It's bdelloid heaven. The only time I have seen such a great quantity of rotifers was in a sample of water + vernal pool dirt.

+Joshua Aguilar These animals are all females. They once had males, but did away with them roughly 80 million years ago. I have spent hundreds of hours watching them and they very much seem to have free will, they have families, they share the duties of watching the kids, they help the new mothers give birth, by being there, touching them, giving comfort. They have 2 eyes, and a 15 cell brain. They feed and rest and sleep. And, they manipulate their surroundings to make it better for the colony. They are very different from us, but they are more like us than not. :o)

What you are saying is the rotifers flagella spin but the heads do not.

@lordvolthotprongs1642 11 жыл бұрын

I have wondered about the fact they "DO" somehow talk to each other. Interesting thing according to a video I saw maybe there heads do spin. I saw a video about how germs operate there long stringy appendages called flagella. The man in video said germs are like a small motor.

@ChaosMagnet 4 жыл бұрын

What is the little offshoot near the rotifers’ heads/mouths? It looks like a short little sticklike antenna or feeler but doesn’t seem to be able to move. What function does it serve?

@BirdWhisperer46 4 жыл бұрын

It's some kind of sensory organ, since every Bdelloid Rotifer is a female, it's not what it looks like. LOLOL this species is 100% female and reproduce asexually. If you buy a cheap microscope, you can see them easily. Also, they are big enough to see swimming in a petri dish.

@ChaosMagnet 4 жыл бұрын

Mitch LOL. Actually, I really didn’t think that it was a genital organ, but now that you mention it....

@BirdWhisperer46 11 жыл бұрын

They do have eyes, maybe sign language. More than once, I have wondered if they can send pressure messages, such as dolphins and whales do. We just don't have the technology to test it. And, just maybe, they decided to KISS and don't need to send any messages cause they got nothing to say. :o))

No, they are copletely harmless. They are everywhere. I think one species can even be found in saltwater. There should be a lot more information about them if you search bdelloid rotifer on Google.

Nothing spins, they just move fast in a rythmical way and it looks like it is spinning. Stop it with a flash and you can see they are just individual cilia.

The thing described as a "hot air balloon"? It appears to be a testate amoeba. These are amoebae that have a sort of shell around them which is called a test.

@timdegraw1784 4 жыл бұрын

I was just going to say that I think it actually might be a rotifer like all the rest but tucked in tightly instead of having its feeding parts out and moving. Watch that part again and I swear you can see the mouth parts tucked down each side and the foot is kind pulled up and tucked tightly inside of the main body for protection I would assume.

+Ajkula 1 HAHA, She, she is touching her penis. All rotifers are females, there have been no male rotifers for 80 million years at least. They reproduce by parthenogenesis. Every rotifer is born with the ability to reproduce her own kind. The penis is her sensor, her nose, and touch sensor. LOL
