One of the nicest, friendliest animals in the world is the dolphin. Dolphins are not only extremely intelligent, but they are also playful and interact warmly with humans.

Dolphins are very social creatures and are able to form deep bonds with humans and other species. According to Dolphins-World, dolphins travel in groups, called pods, and stay with the same pod for their entire life. These mammals develop their own innate sense of community and care for the sick, injured or elderly dolphins in their pods. Dolphins are also very kind to humans. Greek mythology has numerous stories about dolphins helping lost or injured sailors. There are several documented accounts in modern times of groups of dolphins saving humans from sharks and other dangerous sea creatures.
