During asexual reproduction the two valves separate with each valve becoming the new "lid" of the daughter cell leading to a decrease in size of the population over time. Once a size threshold is reached, initial cell size is restored by sexual reproduction during which haploid gametes fuse to produce zygotes that develop into auxospores.
