Some facts about whales:
Spindle cells found in several species of whale and dolphin also indicate the possibility of high intelligence
Dolphins and porpoises use vocal sounds and body language to communicate with one another. Baleen whales communicate over hundreds of miles using complex songs.
They have complex social structures. The social structure of killer whale for example (killer whales are actually dolphins) is often compared to that of elephants and humans, and is even considered by some to resemble a culture.
So why the hell are we hunting and cruelly killing these intelligent, sensitive creatures???
