| Abstract |
The foraminiferan constructs a test and attaches it to the substrate with elastic threads. There are large numbers of symbionts (Diatoms) in its protoplasm; Heterostegina gets its nourishment from them. The film shows test anatomy and organic protective sheaths, cytoplasmic streaming and symbiont transport, local movement with pseudopodia and chamber formation in detail. With time-lapse.
