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.
