Abstract: This paper presents the first data on the early larval morphology of euphausiid Thysanoessa inspinata and T. longipes. Female animals were captured in the Oyashio region during May 2006 and investigated through a 31 day period in a laboratory experiment. Between 76-142 eggs were found to be released from Thysanoessa inspinata during each spawning (hatching success=81-99%) and 136 eggs (hatching success=65%) were released from the T. longipes females. The morphology of T. inspinata and T. longipes during all stages as eggs, Nauplius I, II and Metanauplius larvae were similar, but distinguished significantly by size (T. inspinata<T. longipes).
