CSI: Why Save the Whales?
"They are the largest animals on earth. They include the biggest creature ever to have lived on our planet, the 100-foot long female blue whale. Their sheer size commands extreme respect. And whales and dolphins have large and complex brains. The sperm whale's brain is the largest of any ever to exist, weighing four or five times as much as our human brain and being at least as fissured and convoluted. The humpback whale creates the most complex, long-lasting, repetitive sound patterns of any non-human animal. Noted marine veterinarian Sam Ridgeway has reported findings that the bottlenose dolphin, by a variety of measurements (encephalization quotient, volume of cortex, ratio of brain weight to spinal cord weight, etc.) ranks just below humans and considerably above other higher primates, including gorillas, chimpanzees, and orangutans."
