Researchers analyzed the genomes of North Atlantic blue whales (Balaenoptera musculus musculus) and found surprisingly high levels of fin whale (Balaenoptera physalus) DNA, suggesting extensive interbreeding.

Blue whales, the largest animals on Earth, faced severe population decline due to historic whaling, leading to their current endangered status. The North Atlantic subspecies is particularly at risk. The study aimed to assess inbreeding within this population, crucial for their recovery.
