The reproductive cycles of male and female Anadara granosa and Anadara antiquata which have been
studied and compared by histological techniques showed great anatomical similarity. Gametogenesis is
associated with a system of follicle cells which break down as the gametes approach maturity. The
arrangement of follicle cells is characteristics of the sex. In the female, gametogonia are peripheral to
the follicle cells, whilst in the male they are interstitial. The process of spermatogenesis parallel the
classical vertebrate pattern, i.e. successive layers of spermatogenic cells (spermatogonia, primary and
secondary spermatocytes, spermatids, and spermatozoa) occurring more or less regularly in succession
toward the centre of the follicle. The diameter of the maximum size oocytes is 75μm for A. granosa and
65μm for A. antiquata. Spawning in both A. granosa and A. antiquata is progressing gradually
throughout the year as indicated by the availability of various stages of oogonia and spermatogonia; for
which the highest number of oogonia were those of 25-40μm diameter. The histological study indicated
that both species are iteroparous with planktotrophic type of development, yet performing a short
period of pelagic life (ca 1 month).
