Charismatic, curious, cute, and smart are all reasons the bottlenose dolphin is the most well-known of the dolphins. The upward curvature of their mouths gives them the appearance of always smiling and their extreme intelligence makes them the easiest cetacean to train. Combine this with their friendly looks and it’s no wonder why they are the stars of most aquarium shows and many Hollywood movies. Not only do people have access to viewing them at most aquariums around the world, they are also the most common dolphin found in the wild, living in temperate, sub-tropical, and tropical waters all around the globe in almost every type of habitat.
