Blue Whale Anatomy

The blue whale holds the record as the largest living creature on our planet. Just the heart of a blue whale can weigh close to 200 kilograms. The blood vessels leading out of this heart, especially the main arteries, are so wide that it’s often said a person could fit inside and swim through them.

👉 This incredible fact highlights the truly gigantic and fascinating anatomy of the blue whale.

Half of the genetic code in humans is similar to that of a banana.

Humans and bananas may look nothing alike, but roughly 50% of the genes in a human have counterparts in a banana. Genes act like instruction manuals for cells, guiding how they function. So in a simple way, humans and bananas follow about half of the same biological “blueprints.” This doesn’t mean we’re part banana—it’s just a fascinating reminder of how all living things are connected.
