Dolpin always make a group ,that is these lifestyle and this group so important becouse these need each other example for looking a food ,hunting and to protect these self from predators.

The sound of dolphins can be grouped into three types, that is (1) click for echolocation, (2) bursering described as a screech or bark, (3) whistle usually used for communication. Dolpin also life at depths greater than 200 meters but they will depend to the noise than a light.Dolpin life is more rely to sound rather than sight and hearing. Dolphins cannot breathe under water. They breathe out of their blowhole. This is why we can’t put anything in their blowhole, because this is their route to breathe and make sounds. But they can hold their breath for amazing amounts of time seven minutes. So they do need to come up for a breath . That make doplin including in active swimmer, because they speeds of swiming is 60 km / h or 37 mph . They always swim like activity jumps to the air with the head first and fell back into the water.Some reviewer called this activity is breaching. Dolpin also do not sleep well under water for a long time because they will could drown. Therefore, when they sleep only was half asleep a few moments in a day. They also do migrate if the water gets so cold the temperature in minimum stage. Also they may migrate if the fish supply and feeding habits change and looking for food. They can even travel hundreds of miles just to follow their food supply. Some like cold and deeper water than others. But if there is enough food available then they may just stick to a local area.
