From stomach contents of stranded M. europaeus it is known that they eat primarily squid (Octopoteuthis spp., Mastigoteuthis spp. and Taonius spp.), deep sea shrimp(Neognathophausia ingens) and mesopelagic viper fish (Chauliodus schmidti and Nesiarchus nasutus). The stomach is divided into multiple chambers. The purpose of this is undetermined, as squid and fish are easily digested, as opposed to the tough material eaten by most animals with such stomach morphology.
