For centuries, ambergris has been highly prized for its unique for its use a perfume ingredient.
To investigate the origins of jetsam ambergris—sometimes referred to colloquially as"whale vomit"—a team of scientists led by Ruairidh Macleod from the University of Copenhagen, Denmark, and University of Cambridge, U.K., extracted and analyzed DNA from jetsam ambergris found on beaches in New Zealand and Sri Lanka and compared it with DNA isolated from an ambergris sample taken directly from a beached sperm whale in the Netherlands.
"These results demonstrate significant implications for elucidating the origins of jetsam ambergris as a prized natural product, and also for the understanding of sperm whale metabolism and diet," the authors wrote in the study.
