Evolution
Dolphins are believed to have been around for more than 50 million years based upon the DNA evidence of fossils that have been discovered. The development of different features has occurred over time for the dolphins. They were once land animals and may have fed from the shores of the water. As time went on though it became more important for them to be able to survive in the water to find adequate amounts of food.
Behavior
Even though these dolphins are very social creatures, they don’t form as large of pods as other species. It is typical to see them in groups of only about three or four members. They are extremely playful creatures though which is why so many people really love to watch them. They commonly leap out of water either straight up or at an angle. This is to help remove parasites from the body as they are coming up for air.
Sky hopping is another common behavior which involves only the head being out of the water. They will do this to look around and many people find it to be fascinating.
They can swim on one side at times and then they can also swim on their backs. They often have their mouths open in a way that looks like they are laughing and having a great time. Many people find them very amusing creatures. Experts have studied them to try to make sense out of what they are doing but so far they remain puzzled about a great deal of it.
The younger Chinese White Dolphins have to come to the surface for air about twice as often as the adults. This is due to the fact that they don’t develop their full lung capacity until they are mature. You will often be able to observe these dolphins leaping completely out of the water. This helps to remove their bodies from parasites.
