martySQ Posted February 20, 2011 Report Share Posted February 20, 2011 If dogs and cats have limited color vision, what makes them think sheep can see the different colors? How do they know that... any studies out there? Peaked my insatiable curiosity. Link to comment Share on other sites More sharing options...
Pam Wolf Posted February 20, 2011 Report Share Posted February 20, 2011 I wondered about the sense of smell in the subjects. Did they go to the colour or the smell? Smell is very important in sheep. Also if they recognize other sheep by sight then why do they butt them when they are sheared until they smell each other thoroughly? Link to comment Share on other sites More sharing options...

How do they know that... any studies out there? Peaked my insatiable curiosity. The colors that any species can see is determined by the number of cones in their eyes. So, basically they can count the number of cones in the species eyes and that tells us if they can or cannot see colors and how many colors they can see. http://hyperphysics.phy-astr.gsu.edu/hbase/vision/rodcone.html Kathy Link to comment Share on other sites More sharing options...
