Ru­dolph tor­ment Bl­itzened

Sunday Mail - - NEWS -

IT’S sup­posed to be the rea­son that the rest of the rein­deer called him names. But Ru­dolph’s very shiny nose should never have prompted any teas­ing at all – be­cause rein­deer lack the right cells in their eyes to de­tect the colour red.

While hu­mans have three cone cells in their eyes, rein­deer have two. This means they have sim­i­lar vi­sion to dogs, and strug­gle to dis­tin­guish be­tween red, orange and green.

Pro­fes­sor Martin Stevens, an ex­pert on an­i­mal vi­sion from Eng­land’s Univer­sity of Ex­eter, said this means rein­deer would be un­likely to mock Ru­dolph’s ap­pear­ance.

Prof Stevens, who ques­tioned the ve­rac­ity of the carol at the Sci­ence of Christ­mas event in Fal­mouth, said: “Santa would be able to see the colour of Ru­dolph’s nose ... but the other rein­deer could not.”
