Cá Heo Không Vây: Thiên Thần Tuyệt Diệu Luôn Tươi Cười

We feel we are quite unique and very intelligent. For example, scientists have concluded our smarts to be comparable to that of the powerful vegan primate, the wise gorilla. We are also known to be very sensitive to our surroundings. For example, our species can sense the change in the air when heavy winds and rains are on their way. As a result, we become more active and expressive in our movements, chasing each other around playfully thus causing ripples and waves on the river’s surface. Local humans who have been astute enough to pay attention to us have been able to predict the coming of a storm whenever they see us act in this way.
