Big Ol’ Heart
We always knew whales were massive, but we didn’t know they housed organs that weigh more than the average human. According to this Reddit poster, whale heartbeats can be heard 10,500 feet away or around two miles from the source. Said hearts also weigh about 400 pounds. Holy guacamole, Batman!
Not to mention, those 400-pound hearts can be heard from two miles away. That’s a mind-boggling factlet, folks. It makes sense when you think about it, though. The largest female whales can get, length-wise, is 82 feet. Meanwhile, their male counterparts can grow to 79 feet in length. At least the whales found in the Northern Hemisphere. They can also weigh up to 12,000 pounds!
