Dolphin
Dolphins are one of the large sea mammals. Like most other sea animals dolphins are carnivores (meat eaters). Dolphins are intelligent and friendly animals, so some of them are trained by humans to serve as entertainment in the attractions at the circus or SeaWorld-like parks (also known as ‘dolphinaria’). While in the middle of the open sea, sometimes we see a pod of dolphins swim alongside a boat, jumping up and down to follow the boat’s wake, as if the dolphins are not afraid of humans. There are some stories we've ever heard of course about the people who were saved by dolphins at sea. Throughout history and legend, dolphins are portrayed as helpful and protective of people. Unfortunately, they are also considered as food—killed in harpoon drives like in Taiji, Japan and in the Faroe Islands.
