When it was alive and cruise the human race ’s oceans , megalodon dominate the environs as one of the most indomitable predators that has ever be . Chasing down any nautical mammal to cross its way – fromsealstosperm whales – the massive shark had little to worry about at the top of the intellectual nourishment mountain chain , except maybe other penis of its own species . New research has looked into this giant predator ’s demeanor , and compute how fast the animals could have swam .
After expect at how the speed of modern Clarence Day sharks is linked to predator - prey kinetics , as well as the physiology of the animate being , the researcher generalise their termination to include megalodon : the largest known shark ever to have be . Using these calculations , they found that a megalodon measuring20 meters ( 65 substructure ) longand weigh 48 MT ( 53 tons ) probably swim at an astonishing 5 meters ( 16.5 feet ) per second , twice that of the large support shark , the enceinte livid .

“ The megalodon was an tremendous apex piranha that appeared to cruise the oceans at speeds unrivalled by any shark species present today , ” explained Dr. David Jacoby , from theZoological Society of London , who lead the survey published inBiology Letters . “ The mathematical example not only allows us to approximate the speed of this super - predator , but also helps us to call the movement characteristics of other elusive marine sharks , such as many deep - sea metal money . ”
While looking into the family relationship between swimming speeds of sharks and their metabolism , they train a framework from 64 subject on 26 species that showed they could predict how fast specie were able to move , just by looking at how big the brute were . As shark increase in sizing their metabolism also increases in scale , so the big the fauna , the larger the metabolism . In monastic order to maintain a sufficient menstruation of water over the shark lamella to get enough O to uphold this metamorphosis , the shark must float at a sure minimal speed .
They found that this relationship , between sizing and speed , formed a “ irrefutable grading relationship , ” and was reliable enough to allow for accurate prediction . The researcher then created a model from this relationship , which was shown to closely match the data call for from tracked sharks in the wild . This allowed the researcher to then use the calculation to generalise the speed of exceptional species which are elusive , or in the face of the megalodon , extinct .
The scientists reckon that these figures give a good reading of the minimal focal ratio at which sharks can swim , but spotlight that more enquiry is involve into how other variable quantity , such as water supply temperature and habitat type , might also influence how tight the animals can move . Even so , the kinship they have identified is still able to go for over five separate group of shark , and could be invaluable in helping to learn the behavior and ecology of other fiddling - hit the books coinage .
