Although we often tend to act as though Planet Earth is ours to do with what we please, we actually share it with a vast number of animals. These animals range from the tiniest creatures that are not visible to the naked eye, to enormous giants that make us look miniscule in comparison. Life exists throughout most of our planet’s habitats, from the jungles and mountains, to the very deepest depths of our oceans. One of the most magnificent creatures to live on our planet, that has been able to thrive from feeding in the depths of the ocean, is the sperm whale.
Sperm whales are mammals, and although they can dive very deep, they must resurface in order to breathe. They are generally found in tropical and temperate oceans, with only the largest of males venturing to the extreme conditions of the poles. Once hunted relentlessly for their body parts, they are listed as a vulnerable species but international efforts have seen their numbers stabilize in recent decades.
These majestic giants are wonderful creatures and we are fortunate to share our planet with them. The more we study them, the more wonderful facts we are able to learn about them.
Sperm Whale Fact #10: Very Large Brains
It would seem intuitive at first that those who are most intelligent would have the largest brains. This would mean that humans would have the largest brains out of all animals, but that is simply not the case. Nor do we even have the largest brain in relation to our body size. The title of the largest brain in the animal kingdom goes to the sperm whale, and the animal with the largest brain proportionally is the tree shrew. While the human brain weighs in at around three pounds, the sperm whale’s brain is enormous in comparison at around 17 pounds.
This doesn’t mean that the sperm whale is smarter than us, rather it shows that brain size is not the only indicator of intelligence. There are other factors to take into consideration such as the structure of the brain, and we are still learning more about how such a complex organ actually works. Regardless, sperm whales are still among the most intelligent animals on the planet.
