Giant otter adaptation

The giant otter right now has many features, such as big size, long tails, and semi-aquatic. For the future giant otter, I believe it will have a longer and bigger tail, shorter fur, and longer limbs. For the longer and bigger tail, tails help with a mammals balance, and when the temperature increases, the giant otter will stay on land more, and with land predators there, I believe it will need good balance to get away from the predators. For shorter fur, due to the rising temperatures, it will not need as much fur, since the temperatures are already warm, I believe it will be shorter fur, to adapt to the warm weather. For longer limbs, due to the giant otter in the future staying more on land, there will be higher changes of land predators getting them, as longer limbs will help with getting away from the predators.
