Thats what I was gonna say.

I read the reason they use there tounge is because they dont inhale very much air when breathing, like a mammal for example, so they dont get as much of an air sample. So they stick their tounges out to capture more scent molecules in their enviroment.

Their breathing system is very primitive in comparison to ours since they dont use as much energy as a warm blooded animal would and dont need as much oxygen. Thats why a bad RI can drown them whereas we could just blow our nose or cough stuff up.
