Do you like dolphins and sharks? I love them. I believe they are great. Dolphins and sharks are enigmatic and mysterious animals. There are similarities and differences between them. For example, they are alike because both live in the sea and oceans, they help cure people, and they are similar in the way they hunt their prey.

This means that they share things like space and even food. If the sharks are small, they do not attack dolphins because dolphins will attack them. Another similarity that these animals have is that in their own way, both help to cure people. Dolphins help people by therapy for autistic children, cancer patients, and people with chronic back pain. Also, sharks help people with their cartilage. The cartilage is used for cancer research and as skin replacement for burn victims. Finally, both animals have almost the same way to eat. Dolphins eat a variety of fish that they hunt.

Consequently, they can control prey that is bigger than them.
             Dolphins and sharks do not have just similarities but also differences. One diversity between dolphins and sharks have is that one can be trained while the other cannot. Dolphins can be trained to swim with people or to make shows. For example, they are training to say hi, jump inside a circle, and give kisse...
