Synura video
This is a short video of the colonial, golden alga Synura. These can varying in shape from round spheres to oblong colonies like the one shown in this video. There are a number of other small flagellated algae that can be seen. This is a very busy slide!

Re: Synura video
Very cool - and well imaged. Thank you for posting it.
Re: Synura video
Interesting. Not that I know much about Synura, but I didn't know it formed colonies that were not spherical. Here's a short bit I recorded of Synura near me. https://imgur.com/FSg85yK

Re: Synura video
Very nice!
Could you describe the equipment used ?

Thanks!

I have a Zeiss Photomicroscope III equipped with the original Zeiss DIC setup (prisms in the condenser and a slider in the tubehead). The objective was a 40X Plan achromat. The camera is a Canon 1300D attached to the phototube using an Amscope adapter. I am really happy with the quality of the photos and videos that I can take using this setup, and I use the Canon EOS Utilities software to operate the camera remotely.

Re: Synura video
Beautiful video.
I wonder how they coordinate. Who decides the direction since there is no central nervous system?

Re: Synura video
Free swimming algae are cool, whether solitary or in colonies! As for the lack of a central nervous system, that's true of single-celled organisms in general, and some of them engage in remarkably complex behavior--makes one think that perhaps intelligence is overrated...
Re: Synura video
Another really nice video! Where did you find the sample with so many motile algae, did you have to enrich for them post collection?

Re: Synura video
Hi Wes,
Thanks for the comment. This sample was from this spring. We had received a lot of rain here in NC and this was from a drainage ditch. I had noticed that there was a yellow brown sludge in the water so I collected some with my trusty turkey baster. It was absolutely filled with many different motile green flagellated algae, as well as different species of Synura. In fact, as I tried to compose photos these critters swarmed into the light of the illuminated field of view. It was a little annoying but cool to see.
