ABSTRACT. – The diet of shortfin makos (Isurus oxyrinchus) and blue sharks (Prionace glauca) were studied by analyzing stomach contents of specimens captured by longliners near the Azores Archipelago and between the Azores and the Iberian Peninsula. The diet of the shortfin mako is strongly dominated by teleosts (mainly Scomberesox saurus), while that of the blue shark is strongly dominated by cephalopods (mainly Histioteuthis sp.). In mass of non-reconstituted prey, sea mammals play an important role, especially for the blue shark.
