[BPT04-P06] Estimation of the calcification rate of foraminifera -exceptionally fast extending of the shell-
Keywords:Calcification, foraminifera, FIB-SEM
The foraminifera Spirillina vivipara does not form a chamber, but elongate a tubular test spirally with their cytoplasmic growth. Spirillina vivipara is also known to be rapidly changing generations that can be reproduced in a several days after division of mother cells (Myers, 1936). From our current observations, it was also found that the shell formation is repeatedly carried out in the day, and the elongation rate of the shell is very fast. Therefore, in this study, Spirillina vivipara was used to estimate calcification rate.
In this presentation, we report on the fastest shell extending rate in foraminifera.
