EARLY LIFE-HISTORY OF THE LAND-LOCKED ATYID SHRIMP, CARIDINA DENTICULATA ISHIGAKIENSIS FUJINO ET SHOKITA, FROM THE RYUKYU ISLANDS

Abstract

This paper provides the morphological descriptions on the first to the seventh molting stages of Caridina denticulata ishigakiensis which was reared under laboratory condition and on its egg number and size. The present species bears a few eggs of large size, and the eggs hatch out as non・pelagic larvae of benthic habit. The newly-hatched larvae have the stalked eyes and all the appendages of adult form but uropods, although some zoeal characters are still remained.
