I don't know if I am completely wrong about this but I seem to remember that
elefants have an alternative for sweating or panting: they use their ears for 
cooling down. Their ears are large and have a lot of  bloodvessels resulting in 
a large cooling 
surface. By fanning the ears they cool down.
Don't know for sure if this is information is of any use to you. 
Can't be of any help on the other question..
