I work with many different species of snakes but have noticed in my retics alot of activity inside there pupils when I enter the room. You can see them wake up and take notice to your presence almost immediatly when you enter. It is also funny yet alarming when you turn around and they are staring at you at face level. They are watching everthing you are doing in the room. Fascinating study hope you will expand your scope of study to also include retics as well as some of the other species of constictors.
