Habitat
The distribution of Tamanend's bottlenose dolphin is not fully understood. They are known to inhabit nearshore coastal waters, including bays and estuaries, in the eastern United States from New York to Florida. Additionally, they are genetically related to coastal bottlenose dolphin populations in the Caribbean Sea and Gulf of Mexico, and may inhabit these waters as well. Further research is required to determine if the coastal bottlenose populations in the Caribbean and Gulf are also Tamanend's bottlenose dolphin.
