"Dolphins are emotional, sensitive, vulnerable creatures, probably more so than we are," said Jacques Cousteau in 1953. Their intelligence has been proven.

Opinions may be mixed, but many researchers have serious reservations regarding subjecting dolphins and other cetaceans to any kind of study that restricts their freedom.  Some people might still wonder, like Melville did, "Is the whale a fish?," but we know better today. Cousteau's team was moved to release their subject right away, contemplating their captured dolphin's unequivocal cry. Their many languages are subtle and still largely inaccessible to humans.  My hypothesis is that their "clicking" mode may be slowed down spike chains!  Hard to tell.  One thing that seems irrefutable is that the cetaceans are at least intelligent enough for them to obtain the rights that we primates have - research on the latter being phased out on "primatarian" grounds. 

My opinion is that the cetaceans equally deserve complete freedom, and clean water too. 

What would be your thoughts on this?   Thanks for reading.
