The digestive system of 36 paralarvae and 150 juvenile Dosidicus gigas were analysed to determine the diet. early life stages collected in central south region Gulf California during different years ranged dorsal mantle length (ML) from 2.8 120.5 mm. food content was separated first into identifiable material (IM) non-identifiable (NIM). All contained only NIM stored mainly caecum rather than stomach. Juvenile squid feed on nine prey types: euphausiids, copepods, amphipods, unidentified crustaceans, fishes, cephalopods, pteropods, bivalves polychaetes. IM found stomachs juveniles with increasing number diversity a function body size. In fact, 60 120 mm ML had high stomach fullness percentages half full completely suggesting improvement swimming hunting behaviour as they grow.
