A flagellate colony on a stalk (continued)

A colony of flagellates is attached to the top of a brown stalk. Each flagellate in the colony is busily moving its flagella. Frequently, small food particles are attracted to the colony, but some of them get free and escape by moving along its long stalk.

Commentary by Prof. Yuji Tsukii, Hosei University
This organism is Anthophysa, also called Anthophysis.

There are other organisms, with slightly different names, such as Bicoeca and Bicosoeca.

This is probably because they have been studied in the fields of both protozoology and phycology.
