Memory:Floating eye

The weakest of the ocular pneumatophores, these appear as a large eye that floats through the air looking around and supposedly feeding, but little is known of their prey or method of feeding. Their ability to lock an attacker's gaze and therefore immobilize them might be a trapping method, but appears to be primarily defensive. An eye floating in mid-air, apparently harmless. You notice that it's awfully hard to stop staring at it.
