Poison frog future creature

I believe that the poison dart frog will have sweat glands which will limit the amount of sweat so it can retain larger amounts of water. I also predict that since deforestation will have many plants and species destroyed, including the insects for their diet. So because of the loss of species, they would probably lose more of their toxicity from lethal amounts, to less lethal amounts.Another prediction is that they will have longer legs because there is more open land and less trees which means to get to water, it would be farther distances. So they would need longer legs to traverse those distances. Finally I believe that since there are less high places, that they would not need there mucus, or the sticky factor from their feet, because it would waste less water, and because they would not need to stick to vertical surfaces.
