The present paper is based on the results of laboratory rearing experiment of Saron marmoratus from the 1^st zoeal to 7^th postlarval stage. The ovigerous female of Saron marmoratus was collected from Buleji, Karachi on 09th March, 1996 and maintained in the wet laboratory of Marine Reference Collection and Resource Centre, University of Karachi. Larvae were hatched on 17th March, 1996, at room temperature of 26oC and water temperature 23°C in filtered seawater of a salinity of 35-37 ppt and pH 7.9 - 8.1. All the larval stages of Saron marmoratus are described along with their illustrations, and compared with the available descriptions of Saron marmoratus larvae earlier studied.
