Physical Characteristics


Bottlenose dolphins have two flippers and a tail. They are different than other dolphins because they have a pointy snout that makes them look like they are smiling. Dolphins have a blowhole at the top of their heads that they use to breathe. They have upper and lower jaws that have 20-26 pairs of small teeth. Dolphins have a dorsal fin which keeps them steady while they are swimming and two tail flukes for moving up and down. 


Male dolphins are called bulls and weigh between 300 and 500 pounds. Females, called cows are a little smaller. Newborns , called calves weigh about 25 pounds.


Bottlenose Dolphins have different colors on them. Their upper half is black, blue, or gray. Their sides are lighter and their bottom is light gray or pinkish white. Their colors are different so the dolphin can fool his predators. When they are seen, they don't look like fish.
