    Does a rattlesnakes pupil ever look round? My reason for asking is I have a very small 10" EDB. I have a set of 3mm round pupil eyes to fit it, but wasn't sure how it would look. I know a bobcats pupils can be slit or round depending on the amount of light, it's attitude, etc. but didn't know exactly how it works with snakes. Any info is appreciated.

    Absolutely ......

    They absolutely do .... in dark conditions. Their pupil dialates just like most animals. At night when it is dark their eyes are almost round .... in order to absorb any light that is available. And during the daylight or full moon, etc. their pupils get smaller .... into a slit pupil to keep the light out. Most people encounter rattlesnakes during the day when they have slit pupils.

    Here are some reference pictures that I have taken.
