Bugger me, must be getting too old. Do I here any sniggering from Wim?

Hi Frez, I'm pretty sure it's one of those four-spined Lagerheimia sp. (L chodatii?)
If it is common you could come across them with 4 miniature cells (autospores) within the mothercell, defenitive proof of Oocystis-like things.

What you make of no1?

I remember a certain micscape article were Nessy would fit in really well. Did you have a good time? I stayed near Perth when doing a field coarse, bice area, just too many bloody midges...

Thanks Charlie, yes, resolution is not bad at all on an inverted, just not being able to play with illumination is bothering me... What filters are you talking about, I suppose mesh?? We're using it here glued to a piece of plastic plumbing pipe, works quite economically in amount of filter material...

Nice one Gerd, beautiful!

Hi Piotr, Nothing special, we get 1 liter surface water samples in and sieve 30-50 ml through 10µm sieve, put the concentrate in a 2ml cuvet and count 200-400 organisms. This is really only a check for toxic algae, not quantitative as the samples are 1-2 days in transit anyway... Marsdiep is a rich ...

Hi guys, some new pics from a live sample from the Northsea (coastal area Marsdiep): http://www.photomacrography1.net/images/Ebria_tripartita.jpg.jpg Ebria tripartita, an amoeboid dinoflagellate which builds an internal silica frame. http://www.photomacrography1.net/images/Emiliana_huxleii_7863+7865...

Thanks Ken. I think the first image shows holes, not chloroplasts. If it wasn't brown my first thought would have been radiolarian...

Thanks, Rene.

Guys, any clue to the id's of these is appreciated: http://www.photomacrography1.net/images/20060325_214621_R=10_S=2.jpg Width at the base 15 µm. Stack of 3 with 60/0.8 achromat. Thing was found near the Dutch Waddensea, where both fresh and saltwater organisms can be expected. Also this one: http:/...

You can collect a liter bottle of Lugol's-fixed seawater from your choice of sampling station

you could publish under pseudonym?!

Are you including your images also in the Micropolitan museum??

probably sample drying up slowly. Gently anayway, because when stress levels are getting too high, it will swim from it's lorica.
BTW, they should be phagotropic as well as autotrophic, ever saw one snapping up a bacterium?

Thanks Charlie, I have a bit of red-green colour brightness, really must look at blown up details to have a proper look. Nice, I'm intrigued by those organelles. There are predatory dinoflagellates with eyespots, and those include a lens! Amazing for a unicellular critter, still looking out for one!...

Must be division. Amazing. Quite an umbilical cord...

Well, here it is, everybody going 'Ohhh, yes of course!' http://www.photomacrography1.net/images/Actinoptychus_senarius_A.jpg Valve width around 60µm (all pics from the same diatom!). You wouldn't come across the tilted orientation when using normal slide+coverslip, but in a ml cuvette we do find th...
