Female: The body is moderately slender, with the urosome consisting of 3-5 segments, the genital segment being nearly twice the size of the other two segments and about three times shorter than the cephalothorax. The caudal rami are symmetrical, each bearing six equal caudal setae. The antennule has 25 segments, and the fifth leg is well-developed and symmetrical, with the third exopod segment forming a claw that is knobbed at its base and bears two unequal setae externally. The inner margin of the claw is lined with fine hairs. Male: The body shape is similar to that of the female, with the abdomen being nearly twice as long as the cephalothorax and consisting of 5 segments, with 2 strong spines on the posterior corner of the last thoracic segment. The caudal rami are symmetrical. The right anterior antennae have 25 segments and are modified as grasping organs. The fifth leg is asymmetrical, with the right leg larger than the left. The right fifth leg has two basipod, three exopod, and one endopod segment, with the third exopod segment forming a long, stout, and recurved claw originating from the terminal portion of the second exopod segment. Half of the inner margin of the twisted claw is striated. The third exopod segment of the left fifth leg forms a chela-like structure with a strong spine at its base. The length of the male is about 0.80-1.0 mm, and the female is about 90.0-1.25 mm. The life cycle primarily consists of six different naupliar and five copepodid stages. Newly hatched nauplius larvae lack external segmentations, but significant changes occur at the moult of the copepodid stage, closely related to the adult form.
