what I see is a vast number of very "dumb" creatures and fewer and fewer more intelligent ones.
if we could honestly rate the intelligence of each animal I would not be surprised to see a typical decay type distribution, with human (for now) intelligence at the y intercept and then more numbers of species with lower intelligence levels.
(from http://www.fmrib.ox.ac.uk/...rt/lectures/lecture2/sld023.htm)
this would have to do with the relative benefit of intelligence from an evolutionary point of view: are very intelligent creatures necessarily better adapted than ones just more intelligent than their {predator\prey} relationship requires?
I would also expect this distribution to hold within subcategories, ie primates would have their distribution, and cetacians would have theirs.
certainly it is easy for us to see intelligence in other primates, but that may just be more a matter of our understanding it than the actual levels.
another one for your list is the snow macaque in japan, where inventive behavior has been observed a number of times (and in one female in particular):
Blue Planet Biomes - Japanese Macaque
(I love that picture)
