Turns out, Greenland sharks—those ancient, 500-year-old giants—aren’t having their babies in Greenland after all! Scientists just cracked the case: the pups are probably born way closer to Denmark, deep in the North Atlantic. These sharks are super rare and mysterious, so finding their nursery is a big deal for protecting them (they’re listed as vulnerable). Next up: tracking these elusive babies with satellites and DNA. Shark nursery mystery, kinda solved! #Science #GreenlandShark #SharkWeek
