World’s biggest heart

Blue whale heart

One of the few blue whale hearts ever preserved weighs 180 kilos and is 5’ x 4’ x 4’ in size. It’s the world’s biggest heart! The Royal Ontario Museum extracted the heart from a dead 76 foot blue whale that washed ashore in Newfoundland. Blue whales (Balaenoptera musculus) are the largest animals in the world, growing to about 100 feet in length. Around 5000-10,000 of the notoriously shy blue whales live in the southern hemisphere and only 3000-4000 in the northern hemisphere.
