Capybara Future Adaptations

The capybara has adaptations to live in the rainforest like webbed toes to swim in water and a pig shaped body to float. These are some of the adaptations that capybaras have normally in a rainforest. What if climate change were to destroy their habitats and they had to adapt to a desert? Some adaptations they could have might be growing tails to hold fat and nutrients in their body to survive the harsh climate of a desert. They might also grow longer ears to shed unwanted heat when it gets too hot. For the last adaptation, they might also develop scales to control how much water they lose through their skin. This would help them live in a hot and dry climate.
