Vertebrate vision is one of the best studied and characterised of all biological transduction systems, but most of what is known comes from studies of birds, mammals
and fish. The relative neglect of snakes in modern studies of vision is surprising given that background information from historical studies indicates that snake
retinas are unusual and extremely diverse. Vision biology has also played an important role in debates about the evolutionary origins of snakes. Thus, studies of
snake vision could provide useful new information on vertebrate vision biology and vice versa. I will give an introduction to the topic and present insights from new
research.
