Now : Toucans have a hollow skeleton which helps them fly more and better than any other bird . Toucans also have a sharp beak which allows them to tear apart their fruit and also to break the nuts they eat . Lastly they would have larger beaks to defend themselves . Future : Toucans would have webbed feet to swim in the water if it flooded . All the toucans would also lose the black on them to avoid getting hot if there was a heat wave . They would also have to adapt to going at least 3 days without food if the population of the food they ate started decreasing .
