2. Dolphins live in all oceans on the planet and even in some important rivers. Their environment is in warmer water. The type of dolphin depends on the environment. Many dolphins live in tropical waters because of the variety of food.

3. Dolphins eat most fish, turtles and even some smaller whales. Many dolphins prefer squid, cod, herring and mackerel because they have lots of fat to give the dolphin energy.

4. The dolphin’s biggest predator is the human. Many dolphins die for food and entertainment each year. Sharks, and orcas also can prey on dolphins. As seen on the right, dolphins are rounded up and hunted for food in foreign countries.

5. Dolphins use high frequency sound waves to hunt their prey. This system is called echolocation. Sound waves travel faster in water then in air. Echolocation is more convenient and efficient to hunt prey in murky ocean water. The sound waves produced by the dolphin travel through the water and hit a source of energy, then reflect back to the dolphin so that the dolphin can sense the location and distance of the source of energy.

6. The energy that dolphins use to find objects is called echolocation. Echolocation is used for hunting prey and avoiding harmful predators. Echolocation does come to use when dolphins need to find mates or family members.

7. Everyone loves dolphins because of how kind, peaceful and beautiful they are. Dolphins have fun personalities and seem to be smiling all the time. Dolphins are energetic, friendly and fun! Dolphins are intelligent animals with a great sense of humor. Dolphins are very gentle so they can be very safe to swim with. Dolphins are talented animals that can be trained to do fun tricks.
