If a blue whale were a pop star, it would probably sing "Heart-Shaped Box" by Nirvana at karaoke, and only listen to those tracks with a strong bass, whether hertz or pounds: That's because the blue whale has a colossal heart weighing around 1,300 pounds, and it can hear other whales' songs from up to 1,000 miles away, all while navigating life with eyes the size of a teacup saucer and no tear glands or eyelashes to boot!

12. Little Blue Tenants

Blue whales seem to have taken a page out of the real estate playbook: "size matters." Giving birth must feel like moving day for female whales: Females can have up to 40 little blue tenants throughout their lives, each starting their lease with an impressive 5,000 pounds and 20 feet in length, growing rapidly on a diet of their mom's high-fat milk (50% fat, to be exact). The actual fact: Blue whales reproduce every 2-3 years, and their pregnancies last around 365 days, similar to humans. At just six months old, a calf can already be 50 feet long and double its weight. Now that’s what you call a growth spurt!

What did the blue whale say at the dentist's office? "No cavities, just a 3.5-meter-long, 90-kilogram filter, please!": In all seriousness, blue whales actually rely on baleen plates made of keratin, the same substance found in human nails and hair, to feed on up to 6 tons of krill per day, using them as a water-filtering system while effectively avoiding any dental visits whatsoever!

Who needs a fancy surround sound system when you're a blue whale?

However, contrary to popular belief, they can't hear low-frequency sounds from 1,000 miles away.
