One contender in maximum size among the predatory sharks is the tiger shark ("Galeocerdo cuvier"). While tiger sharks which are typically both a few feet smaller and have a leaner, less heavy body structure than white sharks, have been confirmed to reach at least in the length, an unverified specimen was reported to have measured in length and weighed , more than two times heavier than the largest confirmed specimen at . Some other macropredatory sharks such as the Greenland shark ("Somniosus microcephalus") and the Pacific sleeper shark ("S. pacificus") are also reported to rival these sharks in length (but probably weigh a bit less since they are more slender in build than a great white) in exceptional cases. The question of maximum weight is complicated by the unresolved question of whether or not to include the shark's stomach contents when weighing the shark. With a single bite a great white can take in up to of flesh and can also consume several hundred kilograms of food.
