What are animals thinking and feeling?

What's going on inside the brains of animals? Can we know what| or if| they're thinking and feeling? Carl Safina thinks we can. Using discoveries and anecdotes that span ecology| biology and behavioral science| he weaves together stories of whales| wolves| elephants and albatrosses to argue that just as we think| feel| use tools and express emotions| so too do the other creatures – and minds – that share the Earth with us.
