Communication and complex social groups are two of humanity's defining characteristics. Dolphins can communicate over great distances and form social groups in sizes from mother-child pairs to congregations of pods. Dolphins also exhibit several other social behaviors:

• Dolphin interspecies sex in the Bahamas: "It is possible for conflicts to arise when the two species encounter each other in overlapping areas of their range. Interspecific sexual interactions might serve to diffuse tensions in mixed-species groups."
• Although there is no evidence of a "natural language" among dolphins, they do communicate with each other.
• Spinner dolphins make exclamation point.
