The Smartest Animals In The World
Bottlenose dolphins
Bottlenose dolphins use vocal learning to develop their own vocal signature and communicate with other dolphins. They each get an individual identity through this and they have a whistle which is the equivalent to calling someone by name.
Dolphins form social attachments and will help ill or injured members of the pod. Dolphins have also been known to team up with humans to catch fish as they know this is some of their best chance of a lot of food.
