The Larger Foraminifer Heterostegina depressa - Multiple Fission in Microspheric and Megalospheric Generation

zweidimensionales bewegtes Bild

The protoplasm retreats into the shell shortly before multiple fission. It then flows out through a system of channels before reforming on the shell surface. The second chamber is formed shortly after subdivision into daughter individuals. After a 13 h resting phase the offspring, which are still connected by maternal protoplasmic strands, are dispersed. They settle in the immediate vicinity and start to grow new shells. Time-lapse.
