Tintinnidium protozoa

Post by micron »

This is a phase image of the ciliate Tintinnidium mucicola. The animal resides in a gelatinous lorica covered with small particles. Tintinnidium belong to the Order Tintinnida which contains more then 900 species, most of which are members of the marine plankton community, with a small number of freshwater representatives. This specimen was taken from a freshwater drainage ditch.

Opps - wrong objective! I used a PN multi-immersion 25x/0.80 phase with water.

Very cool! Nice picture. I have never seen them alive. I have only seen empty tests in samples of marine detritus. Freshwater! Looks like a rare find...
