Behavior of Euplotes

Behavior of Euplotes A large ciliate called Euplotes is gathering food with the dense cilia around its mouth. Small flagellates are sucked into the mouth one by one. They are transferred to the food vacuole which already contains plenty of food. One of the caudal cirri near the rear end shows characteristic movement. At first the body seems to be flat when viewed from above. When the organism moves over to a particle, we can see it from the side. It almost lookes like a turtle holding onto the particle with its "hairy legs" (cirri).

Commentary by Prof. Yuji Tsukii, Hosei University
It is difficult to say whether this organism is Euplotes eurystomus or E. woodruffi, because the exact shape of its nucleus cannot be identified.
