What about Dolphins? Comparable intelligence.

[Zachary]

This is in stark contrast to your brothers and sisters who are able to ride freely through the ever-changing waters where food is plentiful and is found with no discernable effort, where all waters are acceptable in temperature, where there is no money to make and there are no goods to buy. There is nothing to store up against a harsh winter or old age. There is only the air to breathe, the water in which to swim, companionship and the dreams, meditations and contemplations of all the years of life.

Beautiful.
