Susan Casey recounts many true stories of dolphins who rescued human beings in dangerous situations.
We also learn about the plight of dolphins in Japan and in other countries where dolphins are killed to be used as commodities. It is equally disturbing to learn that activists who spoke up to protect these creatures were murdered.
The BP disaster had devastating effects on the dolphins, and the presence of oil in the sea continues to affect them.
"Between May 2010 and May 2015, 1,199 dolphins have washed up dead. Those are the only ones that we've found. Given that most dead dolphins don't make it to the shore, their bodies sinking in the deep or being eaten by predators, scientists estimate that the real number of dolphin casualties could be five times higher. And the bodies keep coming."
"The world is full of magic things, patiently waiting for our senses to grow sharper."
