Really nice! "Quite hard" is an understatement. Actually a little surprised at how well they are defined in the second image. (Shutter speed?)pwnell wrote:The first two were a more artistic approach as capturing autofluorescence in vorticella is quite hard - impossible to stack as they move around.
As far as your "unknown". Bears a strong resemblance to an unknown I posted here:

Mine came in with a drag of my plankton nets in salt water... but... we have had lots of heavy rain and it is entirely possible that it was washed into the bay with storm run-off. (Sample was relatively close to shore.) I subsequently found the same subject in a freshwater sample, so I suspect that's what happened. Plant seed of some type? Do they look the same?
