Both ssp of Manouria (Browns /Blacks)need high humitidy. They are the same animal in every way other than Browns are smaller as adults in most but not all cases.In captivity they are known to live inspite of sub-normal humitidy levels as adults but the young will have trubble.Humidity is easy to make with misting systems,sprinkler systems,damp mulch,moss,etc.It is very humid in both ssp range.If they hold their head just slighty out and are not active they are suffering from low humidity.If they hold their head high and have a pulsating neck after misting/foging/raining,they are content.Moments after hatching a baby mt. tort. if misted, will want to eat or drink whatever they are standing on.Long periods of low humidity will cause eyes to remain shut,lack of desire to eat,possable respratory infection,dehydration,immune system crash and the big dirt nap.We do not know how the extreem northern phayrei live in the wild in places like Napul,Bangladesh,Thimphu,and all along the Himalyan Mts.There could be another whole enviromental strategy for survival.
