Первая документированная поимка сельдевой акулы Lamna nasus в открытых водах Юго-Западной Атлантики над подводным северным хребтом Скотия (банка Дэвиса) с замечаниями о популяционной структуре вида в Южном полушарии
The first documented evidence of the porbeagle shark, Lamna nasus (Chondrichthyes, Lamnidae) in the area of the North Scotia Ridge (Southwest Atlantic) is presented. Data on morphometric analysis and plastic features of the identified L. nasus are provided. The porbeagle shark (1 ind.) was caught during the target fishing of the Patagonian toothfish Dissostichus eleginoides in April 2009. The detected coloration peculiarities make it obvious that the so called «black-faced» specimens of Lamna nasus occur in the southern areas of all the oceans and evidence their circumglobal distribution in the Southern Hemisphere.
