Cochliopodium vestitum
Cochliopodium with short spines, zoochlorellae and ingested purple sulphur bacteria

Cochliopodium cf vestitum

The specimens on this page were present in floating debris, sediment which got floated in early spring because of activity of blue algae. The sample was rich of purple bacteria. Remarkable was the difference in length and presence or absence of the spines:
– many specimens had numerous short spines of equal length (4 µm);
– some specimens had fewer but longer spines of somewhat unequal length (8-10 µm);
– some specimens didn’t have any spines.
Most specimens contained zoochlorellae. Some specimens containd purple bacteria as food.
Locomotive cells were shaped like a Bowler Hat and about 45 µm in diameter when sperical.
