The first zoea of Eriphia sebana is described and illustrated in detail for the first time. Its morphological characteristics are compared with those of other known species of the Menippidae from the northwestern Pacific Ocean. The general morphology of it corresponds well with other known zoeas of the Menippidae, except that of Sphaerozius nitidus. It is found that the zoeas of E. sebana and E. smithi can be separated by the exopod of the antenna, which has three setae in E. sebana and four setae in E. smithi.

Ovigerous crab of Sphaerozius nitidus of the family Menippidae was collected from Geojedo, Gyeongsangnamdo and hatched in the laboratory. Digital imaging of live zoeas of the first zoea stage of S. nitidus has been reported for the first time in the world, and its morphology has been redescribed and illustrated. This study is different from former study in that it has three unequal setae with exopod of antenna, 5+4 setae with basial endite of maxilla, and dorsomedial spine and lateral minute spine with fork of telson. The first zoea of S. nitidus has black pigments occurring behind the eyes, on the dorsal spine medially and on the basis of lateral carapace spines, on basal of basis of maxillipeds 1, 2, and posterior margins of somites 1-5, and yellowish green chromatophores on the dorsal spine.
