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?
Humans have so far failed all the tests that crows set up to measure their intelligence

Went down that rabbit hole of training crows to do things. Crows are such amazingly intelligent creatures. There is a whole scene of people teaching and training wild crows silly things.
It's interesting to think about how past a certain level of intelligence and independence it becomes less "training" and more "teaching".
