The first zoeal stage of Pachycheles hertwigi Balss is described and illustrated. Its morphological characteristics are compared with those of other known species of Pachycheles. The first zoeas of P. hertwigi and P. stevensii are very similar, but they can be distinguished from each other by the length of carapace spine and the size of antennal exopod spinules.

The first zoeal stage of Enosteoides ornata (Stimpson, 1858) is described and illustrated in detail. Its morphological characteristics are compared with those of other known species of the family Porcellanidae. In the family Porcellanidae its diagnostic characteristics are the exopod of an antenna armed with a seta and five spinules and the coxa of the first maxilliped having two setae. The former characteristic can be seen in most of the genus Petrolisthes zoeas, while the latter usually in the genus Pachycheles zoea. The Enosteoides ornata seems to be p1aced intermediately between the genus Pachycheles and the genus Petrolisthes based on the zoeal morphology.

The occurrence variations of decapods by season and depth off Oryuk Islets, Busan were investigated at seven stations in April and October 2009, July 2010 and January 2011. Decapods were collected by SCUBA diving at 5 m and 10 m depths. 46 species belonging to 18 families in 3 orders were identified. Pilumnus minutus, Pugettia intermedia, Pachycheles stevensii, and Paguristes japonicus were dominant species, comprising 73.0% of total decapods. P. minutus and P. intermedia were abundant in all seasons (except summer) while P. stevensii and P. japonicus were abundant in fall and summer. Dominant species were divided into three groups (resident species, seasonal species and temporary species) on the basis of their occurrence patterns. P. minutus and P. intermedia were resident species while P. stevensii, P. japonicus were temporary species. The species number, density and biomass of decapods were fluctuated by seasons. They were highest in fall and lowest in winter. This study implied that the variations of species number and density of decapods were significantly related with seasonal change of water temperature.
