"Blue Shark," Wikipedia, the free encyclopedia.Adult blue sharks do not suffer predation on a regular basis, except by killer whales. Young and smaller individuals may get eaten by larger sharks such as the great white shark and the tiger shark. This shark may host several species of parasites. For example, the blue shark is the definite host of the tetraphyllidean tapeworm, Pelichnibothrium speciosum (Prionacestus bipartitus). It becomes infected by eating intermediate hosts, probably opah (Lampris guttatus) and/or longnose lancetfish (Alepisaurus ferox).
