Microphotographs of gonadal tissue of Tilefish (Lopholatilus chamaeleonticeps) functional 
males (left) and females (right): (A) a functional male with seminiferous tissue developing 
directly along a lumen (arrow); (B) isolated oocytes, one partially degraded (left) and one in- 
tact (right), embedded in seminiferous tissue of a functional male; (C) seminiferous tissue of 
an immature male (ct=connective tissue, sg=spermatogonia, sc=spermatocytes, st=spermatids, 
do=degraded oocyte jfully degraded, no cell remaining]); (D) tissue of a mature (developing) 
male (sz=spermatozoa); (E) ovarian tissue of an immature female ( pn=perinucleolar oocyte, 
triangle=oogonial nest); (F) primary growth oocytes, marking the Balbiani body (black arrow) 
and other inclusions that appear to be precursors to cortical alveoli (white arrow); (G) an oocyte 
with advanced cortical alveoli throughout the cytoplasm (arrow); and (H) ovarian tissue of a 
mature (ripe) female (ev=early vitellogenic oocyte [not fully with yolk], mn=migrating nucleus, 
ho=hydrated oocyte, pof=postovulatory follicle). Scale bars vary with image: 50 pm (E, F, G, B), 
100 pm (C, D), 250 pm (A), and 500 pm (H).
