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:

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!
