Introduction
The scientific name for a Bottle Nose dolphin is Tursiops Truncatus.
A dolphin can live up to 45 years in the wild.
A dolphin can live up to 60 in captivity.
A dolphin is endangered because fishermen catch them with other
fish and when people dump trash in the ocean that kills them.
 When beavers put dams in rivers dolphins have to live some where
else.
What Dolphins Look Like
Dolphins are:
 gray because of all the blubber under it.
 about 2-4 meters long.
 weigh between 150 and 650 kilograms.
 Have excellent vision both in and out of
water.
 Have two flippers to swim on the side of
their body
 Dolphins have a blowhole on top of their
head.
 Dolphins skin is really slimy and smooth.
 They have a dorsal fin on top of their back
 Dolphins tails are shaped like a rounded
triangle.
More of How Dolphins Look
 Instead of ears they have ear
holes.
 Dolphins eyes are small for a
mammal but big for a fish.
 Without their eyes they won’t
be able to catch their prey or
their predator won’t be able to
catch them
 Have a nose that is 3 inches long
 Dolphins have 18-28 teeth on
each side of their jaw.
Habitat

 They live in the Atlantic and Pacific
Oceans near Europe and Africa,
South America and North America.

faster to catch food and escape from predators.

a mammal which helps them swim through the water more
easily
Behavioral Adaptation

drown.
 Swims with other dolphins for company and protection

communicate with each other using sonar to help catch
food and warn of predators.

the cold out.
