SEM images of the antenna of Marsupenaeus japonicus: (a) the full view of the antenna, (b) an enlargement of the merocerite from view (a), (c) the origin of the flagellum, and (d, e) enlargements from view (c). The antenna consists of four segments: basicerite (Ba), ischiocerite (Is), merocerite (Mr), and carpocerite (Ca). The antenna flagellum (AF) is composed of band-like straps (St) and successive bands (annulus) (An). Other labeled structures include the scaphocerite (SCa), lateral teeth (LT), three folds (f), small simple setae (SS), long filamentous setae (LS), a small seta with a hole at its proximal end (H), pits (P), antennal spine (AS), and unipennate feather setae (FS)
