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 ...
[3])and Carcharodon megalodon (Average estimated adults size about 16 - 18 m, and a largest size of 20.3 m was extrapolated from ontogenetic trends of the great white shark by Gottfried et al. 1996. [4]) to a human Homo sapiens (180 cm). C. megalodon is only known from teeth and vertebrae, the silhouette shown here is speculative.
The maximum size of the whale shark is uncertain. Various reports suggest individuals around 18 metres (59 ft), but many of these reports lack detailed measurements and documentation. McClain et al. (2015) consider this whale shark as the largest reliably measured. [9] Meekan et al. (2020) studied whale sharks over a 10-year period.
By comparison, the largest known colossal squid beak from a sperm whale stomach measured 49 mm (1.9 in) in LRL. [22] Though the number of large colossal squid specimens known to science is too small to get a good idea of the relationship between beak size and overall body size, a beak of such enormity indicates a truly massive animal weighing ...
Meg 2: The Trench hits theaters this week with a larger-than-life depiction of the megalodon. Here’s what we actually know about the beast, according to scientists.
Size of Paraceratherium (dark grey) compared to a human and other rhinos (though one study suggests Palaeoloxodon namadicus may have been a larger land mammal). The blue whale is the largest mammal of all time, with the longest known specimen being 33 m (108.3 ft) long and the heaviest weighted specimen being 190 tonnes.
