Re: Spirostomum teres

Beautiful images...sort of like the vintage zeppelin airships...I even get a sense of the smooth gliding motion! 1) How did you get so much of these elongated protozoans in near to same plane of focus...terrific images. Are these a collection of 'stiched images' assembled into these final images? 2)...
