Bottlenose Dolphin

Tursiops truncatus

The bottlenose dolphin (Tursiops truncatus) is a robust oceanic dolphin found in coastal waters, bays, estuaries, and offshore habitats in many warm and temperate seas. It has a short beak, curved dorsal fin, gray body, and a social hunting style supported by echolocation, whistles, and learned local behaviors. Some populations are resident in particular bays or coastal regions, while others range more widely offshore. The name covers variation in size, ecology, and behavior that can be important in research and management.

Bottlenose dolphins are kept only by permitted marine parks, aquariums, research facilities, and rehabilitation programs, and their care is technically demanding. Managed animals need large clean marine systems, stable social groups, fish diets checked for quality, trained voluntary medical behaviors, and extensive enrichment. Wild work includes photo-identification, acoustic studies, rescue of stranded animals, and disentanglement when safe. Conservation concerns vary by population but may include boat strikes, fishing gear, pollution, harmful algal blooms, underwater noise, and feeding by tourists that disrupts normal behavior.
