Ya know, I get these riddles one day and the answer the next. When the answer came it said, "None of them. It is impossible to see in TOTAL darkness." I thought , how ! They should have said that was a possibility. Sorry, ladies.
Oh, that's quite ok LuAnn. The only reason I picked bat was because technically they don't "see". But, I also remember seeing a program on owls and if I remember correctly, they did some experiments to see if owls could manuever through "trees" in complete darkness and they were able to. However, this was a while ago and I suppose there might have been a tiny bit of light.
