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 ...
Bloop was an ultra-low-frequency, high amplitude underwater sound detected by the U.S. National Oceanic and Atmospheric Administration (NOAA) in 1997. [1]
The largest shark in the fossil record is the megalodon (Otodus megalodon), a colossal Neogene lamniform. The range of estimates of the maximum length for megalodon are from 17 to 20.3 m (56 to 67 ft), with a mass ranging from 65 to 114 short tons (59 to 103 t). [44] [45] [46] It is also regarded as the largest macro-predatory fish ever.
A new study posits that the ancient megalodon shark was longer and slimmer than previously believed. The ancient shark has been compared to the great white, but it may have more closely resembled ...
English: A size diagram comparing various size estimates for the extinct shark Otodus megalodon to Carcharodon carcharias (great white shark), Rhincodon typus (whale shark), and a human. Also shown are megalodon specimens the estimates are based on, vertebral column IRSNB P 9893, upper anterior tooth NSM PV-19896, and lateral tooth GHC 6 ...

The tiger shark (Galeocerdo cuvier) [3] is a species of ground shark, and the only extant member of the genus Galeocerdo and family Galeocerdonidae. It is a large macropredator, with females capable of attaining a length of over 5 m (16 ft 5 in). [4]
Members of the group include macropredators, generally of medium-large size, including the largest macropredatory shark ever, the extinct Otodus megalodon, as well as large planktivores. [2] Although some authors have argued that the Late Jurassic Palaeocarcharias should be considered the oldest known lamniform, this is disputed.
