The new millennium has brought discoveries about dolphin cognition, emotion, and consciousness, creating a bridge to what is known about dolphin behavior with an emphasis on communication. New data on dolphin intelligence allow us to obtain a broader picture of the inner lives of dolphins. We see that dolphins exhibit sophisticated characteristics previously attributed only to humans and possibly to other higher primates. We know that dolphins understand syntax, semantics, and word order, and are capable of mirror-self-recognition, comprehension of pointing gestures, and understanding reference to body parts. They can identify the same abstract object using vision or echolocation. There is evidence that dolphins have culture. For instance, killer whales have vocal dialects that are distinct to each family group and are passed down through generations; some bottlenose dolphins use sponges as tools when foraging along the sea floor.
