Daphnia Simocephalus vetulus

My first Daphnia, collected in a sample of Mississippi river water. I have a 3 gallon glass carboy I use as a microbe aquarium. Since it gets cold enough to freeze the river solid down to 3 or 4 feet, I use the carboy to keep sample microbes from the river alive through the frozen times. It made it for almost 8 months, but needed recharging.

In the sample were a dozen or more species of copapods and crustacians. I would have been very happy with just some amoeba and parameciums.

Yeah, Simocephalus vetulus. These are the most common cladoceran in my water sample. They seem to be more common and hardier than most Daphnia. Great.

@id5556 Yes, the Amscope is a good scope and it has nice and sharp and bright lenses for a good picture.. If you get a scope with a trinocular port head, then the 40D will mount to it with the proper adapters. Of course, the 40D will not take video though. Before I bought the T1i, I had a Canon 1D MkIII mounted on the Amscope and it worked fine.

Very nice video! Simocephalus sp. one genus of the Daphnie. Can I see your website for other photos?

Amazing video and a great subject to study. Are you using infinity type objectives? What do you think of them?

[Znobyrd]

@BirdWhisperer46 Have not bought any yet. 25mm? Hmm, not sure, it doesn't say in their description, but they told me they will fit the 490B. I wrote another email and asked for a more direct and detailed answer, I need to know they will focus right on my scope or it's a waste of a lot of dollars. Btw, the new 50 watt LED lighting I installed is working great.

@Znobyrd No, I can't use infinity objectives. My scope is 160mm tube length. They look good though, from what I have seen.

[Znobyrd]

Mine is 160mm too, but they sell them on Ams.... website for my scope. I asked them if they'd focus right on it, never got a good straight answer, just said they'd "fit", and they'd "work".

@id5556 I don't use Flickr, cause I have my own websites and host my images there. Then I link to them in various forums, so they are all spread out in different places and over time. I can't post links here for some reason, but if you message me through YouTube, I can post some links to look at some of the images.

@Znobyrd I understood they would not fit cause they are 25mm. Did you buy any?
