Re: surface/volume ratio and water loss in smallest amniotes
A minor note: Wind isn't always disadvantageous to small creatures. Many
insects use wind for dispersal. All a mosquito has to do is climb high enough
and it can experience relatively cost-free transportation for tens of
So the lack of bites might sometimes be due to the fact that the mossies are
waiting in line at the airport.
