Video by bertiegregory | Four fin whales, each having fed on an enormous mouthful of krill, swim past in the waters surrounding Antarctica. A fin whale can eat an estimated two metric tons of krill a day. Considering there were 300 fin whales feeding together, this gives an idea of the richness of krill here. Filmed for “Epic Adventures With Bertie Gregory,” now streaming on disneyplus. #EpicAdventures #EpicAdventuresWithBertieGregory
