Euglena sanguinea from a pond [not Haematococcus!]

Post by viktor j nilsson »

Today I found a nice bloom of what I believe to be Haematococcus pluvialis that also contained some intresting ciliates etc. [Edit: Euglena sanguinea, not Haematococcus!]

It seemed like a good opportunity to actually try to produce some photos with my microscopes, and not just buy more stuff. So here goes:

All taken with my Olympus Vanox AH, DIC, FK2.5x, Canon 5DmarkII, DIY flash illuminator.

Euglena images: Olympus SB Apo 40x 1.00 HI
Ciliates: Leitz 50x 1.00 170mm water immersion.

Any feedback much apprectiated!

Anyone knows what this thing is?
Added the composite to show its funny behavior, slowly gliding forward, squeezing into tight spaces.

Those are really beautifully lit and composed shots.

Perhaps a video would show the subject better

This is not Haematococcus, it is Euglena sanguinea.

Yes, I eventually identified the slowly moving red blob in images 1, 5 and 6 as Euglena sanguinea. But the red-green algae it's moving around among is surely Haematococcus.

You know, I am actually starting to think that all of them are Euglena sanguinea. Do you agree?

I found this image which really resembles the spherical stage with red center and green periphery:

And this image that really resembles the smaller, all-green spherical stage with red eyespot:

From: https://sagdb.uni-goettingen.de/detaile ... er=1224-30

It did not occur to me that they were all different stages of development of the same organism, but it makes a lot of sense. Thanks for helping setting me straight!

Wow Viktor!

Very nice photographs.
I have seen some DIC images where the color pallete is just really beautiful, like yours is here. How do you achieve this?
Is it playing around with your prism allignment, or using a wave plate? Or is it just that some prisms and sliders in combination produce this effect and it is not achievable without the right equipment.

Hope to hear from you!

Kind regards, Mas

Thanks! Nothing special, just the regular AH-NIC setup, properly aligned and with objectives that work well with it. There are definitely some regions of the color palette that I find more appealing, especially the medium gray and deep blue regions. I find it quite hard to produce good looking photos with more colorful backgrounds.
