Similar in an intuitive way.

As for the fish, I don't know, it depends how the aliens are thinking and communicating. In this respect, I don't feel much similarity with fish anyway.

As for the collie, very probably we are more similar. And I would probably care more about border collies than about crystalline baby-eating aliens. If you have a dog, you can probably imagine that the relation between a man and a collie can be pretty strong.
