Tests show Arctic reindeer 'see in UV'

Arctic reindeer can see beyond the "visible" light spectrum into the ultra-violet region, according to new research by an international team.


They say tests on reindeer showed that the animal does respond to UV stimuli, unlike humans.


The ability might enable them to pick out food and predators in the "UV-rich" Arctic atmosphere, and to retain visibility in low light.


Details are published in the The Journal of Experimental Biology.
