Despite their size , defective repute , and Hollywood stardom , there ’s still a lot we do n’t eff about heavy snowy sharks . That ’s especially true regarding their Atlantic Ocean migration . A new study has looked into this mystical aspect of their behavior , only to consolidate their place on the list of the world ’s most awesome animal .
It turns out that Atlantic expectant white shark drown agency farther offshore than we thought , sometimes have 3,701 - kilometer ( 2,300 - mil ) trips from Cape Code in the US to the Portuguese island of Azores .
They also ofttimes dive to insanely deep depth of 1,128 metre ( 3,700 foot ) . Only a diminished amount of sunlight penetratesbeyond 200 meters ( 656 feet),and by 1,000 meter ( 3,280 feet ) there is no luminousness at all in most parts of the earthly concern . That means nifty white are swim around in the pitch - black aphotic , or “ midnight ” , zona of the Atlantic .
However , it is still a mystery as to why they drown such great distance , although it ’s in all probability link up with some sort of seaward forage facilitated by the caloric physiology of the species . The research worker are also appear into how climate alteration could be affecting the shark ’s migration routes .
" These sharks moved daily to depths of up to 1,128 meters , spending pregnant time at specific mesopelagic deepness zona through a temperature range of 1.6 to 30.4 ° C [ 35 to 87 ° F ] , " the study writer write in the journalMarine Ecology Progress Series .
The research was done by scientists from the Massachusetts Institute of Technology and the Woods Hole Oceanographic Institution , as report by theAssociated Press(AP ) .
“ Everything we get it on previously indicate that the snowy shark in the Atlantic is more coastally - orient , go north - to - south and remaining on the continental ledge , " Gregory Skomal , the cogitation ’s lead source , told the AP . " So what we ’re now describing is this other component , this seaward motility into overt ocean . "
They came to these findings after tracking 32 shark with artificial satellite - establish tags between 2009 and 2014.They found that these Atlantic shark follow a north - south migration route along the eastern coast of the Americas , manoeuvre up northward in the warm summertime calendar month , then down south to South Carolina , Florida , Georgia , and the Bahamas for the wintertime .
