An interesting, non-sensationalistic and well-documented study of the comparative intelligence of man and the larger cetaceans (dolphins, whales, etc.), reaching the conclusion that while much more study is needed, it is possible that some of the species are of at least equal intelligence to man, and deserve to be protected in every way while they are studied, and given every respect (by virtue of benefit of the doubt) as a family of animals that may be our intellectual match - or superior.
