Re: I am sure this has happened to someone.
In my opinion eyes are definitely useful for finding prey. Personally I think that many of the picky eaters like confirmation from all three senses before they strike.
Some snakes will strike at scent without any regard for heat, some will strike at heat without a tongue flick, then some will strike at anything they see. The ones that go off smell and sight alone are comical. I can't help but laugh when they strike at some movement in the distance and smack their face on the tub. I feel really bad when it happens repeatedly:rolleye2:. These ones could definitely use some training using their IR senses:).
