How much does a blue whale heart weigh?
Blue whale heart weighs about 180 kg (397 lb).
🐕 That's about the weight of 6 labradors — or 18 car tires 🛞, or 13 bicycles 🚲.
At 180 kg, it ranks #14 of 15 in Weird & Surprising (lightest to heaviest) — heavier than Car engine (160 kg) and lighter than Liberty Bell (943 kg).
This object made the catalog specifically because its weight defies expectations — one of the most surprising entries here.
A blue whale's heart weighs as much as a motorcycle and beats only 8-10 times per minute.
