I'm curious: Your comment implies that you find the title misleading.
What would you suggest instead?
How about very small gaps instead of "too small gaps". Simple change to the title, but far more accurate and non-contradictory.
But would you still click on it?
"How octopuses squeeze through an opening far smaller than the body diameter" is boring, verbose, and a quote from the article.
I think adding ‘seemingly’ would cover the basis of violating the law of contradiction.
