10 Intelligence

Speaking about their intelligence, elephants have one of the more intelligent animal brains on Earth. Their brain weighs a whopping 5 kilos. That is more than the brain of any other land animal. Only whales beat them when it comes to the complexity of the folds in the brain; the more complex the folds, the more intelligent the animal is. Elephants can show grief, compassion, and self-awareness.

They can understand the use of tools and be cooperative and have shown excellent learning abilities. Studies have shown that these guys are more capable than humans in keeping track of multiple objects in 3D space. Elephants accurately memorize the many kilometers of trails they walk on and then walk them for a long time.
