SEM images of the antennule and scaphocerite with setae structures of Marsupenaeus japonicus: dorsal view of the eye stalk (a), rostral part of the scaphocerite (b), medial flagellum of the antennule (c), and lateral flagellum of the antennule (d). The antennule peduncle consists of a distal segment (DS), intermediate segment (MS), and proximal segment (PrS). The distal segment is extended by stylocerite (ST) and gives rise to two flagella: the thin medial flagellum (MF) and the thick lateral flagellum (LF). The scaphocerite (SCa) is primarily oval with a spear-like lateral edge (LS) and a tapered end (Te). Other labeled features include the rostral semicircular part (RS), folds (F), long plumose setae (PLS), setae articulation (SA), apical part of rostrum (AR), annulus (AU), simple setae (SS), pores (P), and aesthetasc (Aes)
