Parasites

The great white shark is the definitive host of two species of tapeworms from the genus Clistobothrium, these being Clistobothrium carcharodoni and Clistobothrium tumidum, both of which infect the shark's spiral intestine. The former is believed to be transmitted to great whites through the consumption of infected cetacean prey, namely the spinner dolphin (Stenella longirostris), Risso's dolphin (Grampus griseus), and the common bottlenose dolphin (Tursiops truncatus), all of which serve as intermediary or paratenic hosts of the tapeworm. The latter species of tapeworm's transmission vector is currently unknown, but it is unlikely to share the same intermediary hosts as Clisbotherium carcharodoni. The intensity of Clistobothrium carcharodoni infestations in affected great whites is extremely high; in one case, up to 2,533 specimens were recovered from the spiral valve of a single great white.

There are two recorded instances of the ectoparasitic cookiecutter shark (Isistius brasiliensis) targeting subadult great whites off the coast of Guadalupe Island. However, the relative dearth of predation records indicates that great whites are not a common food source for cookiecutter sharks, and that cetaceans and pinnipeds - especially the Guadalupe fur seal (Arctocephalus townsendi) - are preferred over great whites; in part due to the higher caloric content of their blubber, and in part due to the higher risk of retaliation from victimized great whites.
