3 Page 1 Habitat Bottlenose dolphins mainly live in the Atlantic, Pacific, and Indian oceans. They travel in pods. Dolphins mainly live in the Atlantic, Pacific, and Indian oceans.

4 Page 2 Class Dolphins are in the mammal class. Also dolphins are a vertebrate, because if you are a mammal you are a vertebrate. What makes dolphins mammals are that they breathe air, give birth to fully formed young, and when they are born they have whiskers on their upper jaw, which soon fall off. If you look closely, on this baby dolphin you will see whiskers.

5 Page 3 Prey and Predators Bottlenose Dolphins eat small fish, such as mackerel, rarely squid, crab, shrimp, and other small animals. Dolphins don't chew their prey, so when they are with a pod they work together to rip apart their prey equally then eat it. Dolphins predators are sharks, Orca whales, and Killer whales. Dolphin's prey are small animals and fish. This is also the movement of energy.

6 Page 4 Behavioral Adaptation Migration Dolphins live in the Atlantic, Pacific, and Indian oceans. If they are in the Atlantic Ocean (which is colder than the Pacific Ocean) they have to migrate to the Pacific Ocean for warmth. Also dolphins might have to migrate for the need of food, or a better habitat. Without migration, dolphins might not have enough food, the right habitat, or they are too cold. This is a pod of migrating dolphins. This is a happy pod of dolphins!!

7 Page 5 Structural Adaptations Echolocation Eyes teeth Fins Blowhole Bottlenose dolphins use echolocation to find food. Without this adaptation, dolphins won't be able to catch their food, and won't eat. Dolphin's eyes are nearsighted above water, but underwater their eyes are perfect for them. Dolphins eyes are covered in protected mucous, which keeps seawater and bacteria from irritating their eyes. Without mucous dolphins wouldn't be able to see. Dolphin's teeth allow them to grasp slippery prey, that they are trying to catch. Also their teeth allow them to fight with predators if they are trying to catch them. If dolphins didn't have teeth, they wouldn't be able to eat fish and fight away predators. Dolphin's fins let them swim up to 25 miles per hour. If dolphin's fins couldn't let them swim fast they wouldn't be able to catch up to prey, and escape from predators. Their blowhole lets them breathe when they get to the surface of the water. If dolphins didn't have blowholes, they wouldn't be able to breathe and stay alive.

8 Page 6 Change in Weather Dolphins migrate, migration is a behavioral adaptation for dolphins. They migrate for warmth, food, or habitat. Dolphins either migrate for warmth, food, or a new habitat.

9 Page 7 Human Impact Dolphins can be effected by humans with boat traffic, habitat destruction, pollution or hunting. Pollution can make the water dirty and can get into the body of dolphins. Many people hunt bottlenose dolphins for meat, leather, and fertilizer or animal feed. Dolphins can be effected by boat traffic.

10 Page 8 Fun Facts Bottlenose dolphins are the dolphins that are found performing at aquariums. Look at this link of a bottlenose dolphin performing at Sea World! Bottlenose dolphins can swim from 5-12 km per hour.
