There are thirty two species in this most diverse Cetacean family and all are highly intelligent and social animals. The common dolphin is most beautifully marked and streamlined with a long beak and pointed flippers. Living in hierarchical groups of 20 to 100 or more, they sometimes join together to form huge pods. Feeding on fish and squid which they hunt by using echo-location, they are capable of diving for as long as five minutes to depths of 280 metres. With the same number of cells and layers in the cortex of their brain as man their intelligence in terms of brain volume, convolutions and social interactions among individuals exceeds that of humans. However, although they have behaved benignly and in many cases affectionately towards us, we have systematically slaughtered them.
