Gametogenesis in planktonic foraminifera.
Gametogenesis in Globigerinella aequilateralis and Globigerinoides sacculifer in culture is preceded by sinking of the organism and loss of its spines. Hundreds of thousands of flagellated gametes, about 5 micrometers in diameter, are produced within the parent shell and released within a period of 13 hours.
