Encountering of two different amoebae II

Two kinds of amoebae of different size and shape are coming in contact with each other, and then move away.

Commentary by Prof. Yuji Tsukii, Hosei University
The amoebae shown in the upper part of the video may be Vexillifera or floating Vannella.

The amoebae appearing later may be Diaphoropodon, which is in a shell covered with black particles.

Diaphoropodon is characterized by fine spiny projections on the surface of its shell, but to see these projections clearly requires higher magnification and resolution.
