SEM images of the optic stalk with setae structures of Marsupenaeus japonicus: (a) dorsal view of the eye stalk, and (b, c, d) enlarged views of the highlighted areas from the previous image. The following structures are labeled: cornea (C), attached bony palate, optic calathus (Oc), basal segment (Bs), ocular plate (Op), antennal flagellum (AF), antennal spine (AS), orbital spine (OS), and various setae (S), including long plumose setae (PLS), simple setae (SS), pappose setae (PS), and long setules (LSu). Additional features include setae sockets (SK), semicircular folds (SF), complete circular folds (CF), folds (F), pits at the same level (P), and volcano-like pits (VP)
