Bottlenose Dolphin
Tursiops truncatus
Quick answer
Bottlenose dolphins are highly intelligent marine mammals found in warm and temperate seas worldwide. They live in social groups called pods, use echolocation to navigate and hunt, and communicate with clicks and whistles, including signature whistles that work like names. They typically live 40 to 60 years.

Intelligence
Bottlenose dolphins are among the most intelligent animals on Earth. They use tools, recognize themselves in mirrors, solve complex problems, and teach skills to their young, such as covering their snouts with sponges to protect them while foraging.
Echolocation and communication
Dolphins navigate and hunt using echolocation, emitting clicks and interpreting the echoes to build a sound picture of their surroundings. Each dolphin develops a unique signature whistle that functions much like a name within its pod.
Conservation
Bottlenose dolphins are listed as Least Concern overall, but local populations face threats from accidental capture in fishing gear, pollution, habitat loss, and disturbance. As air-breathing marine mammals, they are sensitive indicators of ocean health.
Frequently asked questions about the Bottlenose Dolphin
How intelligent are dolphins?
Bottlenose dolphins are among the most intelligent animals known. They use tools, pass the mirror self-recognition test, solve problems, and teach learned behaviors to their offspring.
How do dolphins use echolocation?
Dolphins produce rapid clicks and listen to the returning echoes to locate objects, prey, and obstacles. This biological sonar lets them hunt and navigate even in murky water.
Do dolphins have names?
In a sense, yes. Each bottlenose dolphin develops a unique signature whistle that other dolphins use to identify and call it, functioning much like a name.
What do bottlenose dolphins eat?
Bottlenose dolphins are carnivores that eat fish, squid, and crustaceans. They often hunt cooperatively, herding fish into tight groups to feed.
How long do bottlenose dolphins live?
Bottlenose dolphins typically live 40 to 60 years. Females generally live longer than males, and some individuals have been documented living into their sixties.
Are dolphins fish or mammals?
Dolphins are mammals, not fish. They breathe air through a blowhole, are warm-blooded, give birth to live young, and nurse their calves with milk.
Social life
Dolphins live in fluid social groups called pods, cooperating to hunt, raise calves, and defend against predators such as sharks. They form strong, sometimes lifelong bonds and have been observed helping injured companions reach the surface to breathe.
