Trachelomonas

Post by Charles Krebs »

When I find these small euglenid flagellates in a sample there are usually plenty of them present. They reside in a a small lorica, and have a single long flagellum that emerges through an opening at one end. Here are a mix of "new" and older specimens. The new loricas are clear, but grow darker with due to ferric hydroxide and manganese salts. This is the first time I have really noticed a "colorless" species. Normally the ones I have found are green.

Hi Charles,
very nice look into the loricae! I've never seen the colorless ones, too.
Regarding the density of lorica the same phenomenon exists e. g. with Arcella loricae.
