People often say that dogs are the most intelligent animals, but dolphins are also a very intelligent species. Dolphins' habitat is in the sea; so many people misunderstand dolphins with fish. In fact, they are mammals, and of course they also give birth of baby dolphin instead of eggs. They spend most of their time underwater, but sometimes they have to come up to the surface to get air like any other mammals. Their breathing activity involves expelling stale air from their blowhole, and then they inhale fresh air into the lungs. Dolphins are often regarded as one of most intelligent animals on Earth, although it is hard to say and prove just how intelligent they really are. They are highly social animal, and research shows that they establish strong social bonds among their pods. They will stay with injured or ill ones, and they even help others to breathe by bringing them to the surface if needed. They can learn from other animals, they show great cooperation in hunting, and they even express different shades of emotions. Due to these significant characteristics, people tend to take them from the wild then train them to do tricks in entertaining shows at some big aquariums. Many people consider them as friendly animals and even friends to human because there are stories about dolphin sometimes help sailors to find the right way to the shores, or sometimes they even protect human from predators such as sharks. However, some countries such as Japan and Peru consider dolphin as one of their favorite seafood. Japan is well known for its dolphin hunting in mass amount, and those drive hunts always result in bloody shores with hundreds of dead bodies of this beautiful creature. Some organizations have developed to protect dolphin from being slaughtered barbarically, but it is still a hard process since dolphin meat is considered as a part of traditional cuisine in those countries. I love dolphin very much, and I hope that people will stop taking advantages from those intelligent and friendly animal.
