Teuthophrys trisulca trisulca

Posted by sonntag

Teuthophrys trisulca trisulca lives in a mutualistic relationship with green algal symbionts. This relatively large – up to 0.3 mm – ciliate catches small multicellular organisms (e.g., rotifers) as food. Teuthophrys trisulca trisulca can be found in lake plankton.

Epistylis anastatica is a peritrich ciliate that is attached with a stalk to animals. Here, the ciliates stick to the backside of a planktonic copepod (see also pictures below for more details). The ciliates can form large colonies including many individuals. This duet was found in lake Mondsee (Austria).

Stentor amethystinus

Posted by sonntag

Stentor amethystinus is a trumpet-shaped ciliate with a violet to purple appearance.  The ciliate is almost 1 mm long and common in lake and pond plankton. Inside the ciliate unicellular algae (the globular green cells) live in symbiosis with S. amethystinus. Stentor is the Unicellular Eukaryote of the Year 2014. This population was sampled by Samuel […]
