why aren't there any green mammals?
Very true. Some years back we were visiting Rathambore National Park in India. In the middle of dense (green) woodland our guide suddenly whispered "Tiger" and pointed. We looked hard but couldn't see anything until we realised the 2 year old male was less than 3m away looking straight back at us. Like some bizarre optical illusion, one minute it was invisible the next there's a huge orange, white and black creature there.Try spotting a tiger in scrub..
tho a green coat would be handy at times.
isn't chlorophyll the reason?
Not green though!
