Or just that it needs to focus on from of itself like filter crabs, or that it needs to see through things like kelp forests or hole enterances.

Given it's size and the extreme binocular vision, it's unlikely to have any ambush predators.

I looked it up, it has bony plates all over it's body and likely a lateral line, so seeing predators directly may have been less necessary. It was also a suction feeder, so likely an active predator of much smaller things. It may have needed good forward vision because it's maneuverability was poor.

That's what I thought! I'm too stupid to make anything more of it here for this community though
