English: Size comparison of Carcharodon carcharias (Great White Shark; Average size under 6 m and a largest size 6.4 m, possibly to over 8 m. ^[1]), Rhincodon typus (Whale shark; Average size between 9-10m, some specimens over 12 m. A largest verified specimen is 12.65 m^[2], however, several specimens over 18 m in length have been reported.^[3])and Carcharodon megalodon (Average estimated adults size about 16-18 m and the largest estimated size 20.3 m^[4],and a largest size of 20.3 m was extrapolated from ontogenetic trends of the great white shark by Gottfried et al. 1996. ^[5]) to a human Homo sapiens (~1.8m). C. megalodon is only known from teeth and vertebrae, the silhouette shown here is speculative.
