4. Elephant
Elephants have huge brains, which would suggest they have some form of intelligence. They have been known to use tools in the wild and clean their food before eating. They are also very good at following the commands of humans when in captivity. They are also extremely caring and have a very clever way of protecting their young. Also, all the females of a herd will take turns babysitting the young elephants.
One elephant named Happy recognised herself in a mirror, which was a great feat as it’s something only humans, great apes and dolphins have been know to do.
