Megalodon was the swelled fish ever to swan the oceans and while many bask indulging in the concept that they may still exist somewhere on earth , The Atlantic Shark Institute ( ASI ) had to do a forked take when one appeared on their fish discoverer . The skim technology had picked up what looked to be an enormous fish " about 50 feet [ 15 meter ] long , librate in at 40 long ton "   – could it be megalodon ?

The reply , disappointingly , is no , but the ensue image does make for a surprisingly convincing megalodon silhouette complete with dorsal fin . As for what the live chunk actually was , it turned out to be a school of Atlantic mackerel .

After recognise the giant , ASI said they “ hold off for one of the perch to go off however , much to our dashing hopes , the shape start to transition into a enceinte shoal of Atlantic mackerel that hung around the boat for about 15 minutes , ” onFacebook .

“ So close , but so far ! The Megalodon ( Otodus megalodon ) , vanish more than 3 million age ago and will likely stay that way , but , for a few minutes , we thought he had returned ! ”

At the estimated size of 15.2 meters ( 50 feet ) , the lineation was on track for megalodon which is forecast to have stretched to16 meters(52 feet ) with finds the size of it of an adult human ( though some citizenry argue we ca n’t really know for certain how big they were ) . It ’s thought thatcold watersmay have had something to do with their capacity to go super - sized , but since then modern shark species have continue to more modest trunk plans .

Megalodon is all well and beneficial for some marine - themed horror , but could they still be out there lurking in the ocean deep ? They locomote extinct millions of years ago , and while an absence of evidence is n’t grounds of absence , it would seem unusual for someone not to have spot a carcase or tooth in living memory .

As for the ocean abstruse theory , what we know of megalodons indicates they occupied shallower waters and had nurseries in coastal regions . Should they have go deep ( perhaps to avoid us ) , you would still expect some mark , as we ’re well aware of the giant , deep ocean squid species still alive today .
