Study homes in on elusive Greenland sharkA new study of the mysterious Greenland shark has revealed the likelihood that specimens are born in the deep mid-Atlantic and then move closer to Europe as they enter their teenage years. The new report, carried out by scientific institutions in Canada, Greenland, Iceland, the Faroe Islands and Norway, examined the size, sex and life-stage of 1,610 Greenland sharks from 11 regions. A rarely seen Greenland sharkIn southern Arctic Canada and north-western and south-eastern Greenland, adult females were most often encountered in offshore waters. Large juveniles were encountered in most regions but dominated in Skagerrak and in offshore southern Arctic Canada. In light of their findings the scientists say they want safeguarding for the large and potentially mature females in inshore and offshore waters of south-west Greenland, the offshore waters of southern Arctic Canada, south-east Greenland and Iceland.
