How comparable is the intelligence of crows, dolphins, octopi and non human apes? Somewhat or not at all? There seem to be a host of things that each of those can do. Can apes do all of those things and the other groups just a few things each? Is there a huge leap of separation or does the leap come between us and them? Is it in any way quantifiable?

A lot of it comes from communication. We don't know how intelligent some of these things are simply because we can't communicate with them.

For apes and gorillas we can communicate. We've taught them sign language so we know hands down in terms of language we beat them. But for dolphins and octopi, we just don't really know.

The way I understand it is that we have thought apes words but we have never thought them grammar.

They are unable to derive consistent meaning from the structure of a sentence. They are incapable of understanding sentences, and that might be the thing that sets us apart. They might be able to understand some vague association between two or three words when put together but at most they perceive it as a bag of words.
