Morphological observation of Mulinia lateralis at 30–60 dpf. A Photograph (left panel) and schematic diagram (right panel) of the anatomy of M. lateralis showing the internal structure (the left shell valve was removed). Anterior toward left and posterior toward right. B Anatomy of M. lateralis from 30 to 60 dpf showing the shell height. The red dotted lines mark the gonad we collected. C Histological observation of the gonads from 30 to 40 dpf. D Paraffin sections of the testes from 45 to 60 dpf. E Paraffin sections of the ovaries from 45 to 60 dpf. Cc, ciliated cell; Cs, crystalline style; Ct, connective tissue; Dg, digestive gland; Ec, epidermal cell; Fc, follicle cell; G, gill; Ga, gonadal anlage; Gsc, germ stem cell; H, hemocyte; Ig, indistinguishable gonium; IT, intestinal tract; Mo, mature oocytes; Oc, oocyte; Og, oogonia; Sc, spermatocyte; Sg, spermatogonia; St, spermatid; Sz, spermatozoa
