    Did you know, that mammals have poorer colour vision than fish, birds and insects?  They have 4 colour "channels"; humans have 3.

    And that the Australian marsupials have colour vision different to primates?  They have 3 "channels" but include UV - so what they see is different to what we see.

    Other mammals have only 2 "channels" - not much colour
