Vorticella

I spent a lot of time looking at a mysterious creature near the dead of daphnia(water flea). But I couldn’t find out the name of it. It looked like a bell which was alive. At last, I found out the name. It was a vorticella.

This had a small propeller kind of thingy on its round edge to suck water. It was eating small bacteria and when bacteria did come, it covered its mouth very quickly, then getting to its normal bell shape, propelling to suck water again.

I love the way it moved its propeller. It was so cute. The better thing about it was that it clasped its lid so quickly that I jumped every time it did it.

I could see its inside because it was transparent. They had about 4 circles inside. I love its fabulous looking creature.
