The Larval Development of Petrolisthes japonicus (De Haan,1849) (Decapoda, Porcellanidae) in Laboratorv Culture
갯가게붙이(Petrolisthes japonicus)의 유생발생
Abstract
The lanral characters of Petrolisthes japonicus (De Haan, 1849), Porcellanidae, were described and illustrated. The lanral development of P. juponicus includes the two zoeal and one megalopal stases. The first and second zoeal stases lasted about 4 and 10 days, respectively. It took about 14 days to attain megalopa from hatching-The larval characteristics of P. japonicus were compared with those of other knouts species of Petrolisthes. Consequently, the lanrae of P. japonicus are more closely related to P elongatus and P ornutus than other Petrolisthes species, but the present species can be distinguished from these Petrolisthes species by morphological characteristics.
