I read that they judge distance by focus instead of using binocular vision. Their eyes can be focused for different distances and they know what distance it is focused for. They need to know the distance to use their tongue attack.

My understanding is that they change to stereoscopic vision when focusing on prey. I didn't realize they can judge distance using a single eye, thats impressive.

To be fair tho they do miss sometimes and get confused as to what they are looking at. They prefer to face foods directly and use both eyes if they can. They seem to get really focused in on their foods.
