A 2015 study linking shark size and typical swimming speed estimated that megalodon would have typically swum at 18 kilometers per hour (11 mph)–assuming that its body mass was typically 48 t (53 short tons; 47 long tons)–which is consistent with other aquatic creatures of its size, such as the fin whale (Balaenoptera physalus) which ...
Balaenoptera sibbaldii Sars 1875. The blue whale (Balaenoptera musculus) is a marine mammal and a baleen whale.

[a] The blue whale's long and slender body can be of various shades ...
Size comparison between a human and two species of Basilosaurus, B. cetiodes (dark blue) and B. isis. The heaviest archeocete, and possibly the heaviest known mammal was Perucetus, with weight estimated at 85–340 t (84–335 long tons; 94–375 short tons), while length is estimated at 17.0–20.1 meters (55.8–65.9 ft) .
