The green Anaconda, the heaviest snake in the world, lives in Mangrove rainforests forests and swamps in South America. Because of global warming, in two thousand years from today the ice in the Arctic and Antarctica will melt completely, ocean waters will rise and flood the rainforests, turning them into oceans. The anaconda adaptations to the ocean could include: smaller and lighter bodies, so it is easier for them to swim in the ocean (locomotion); gills for breathing and fins for swimming, change skin color from green to blue to camouflage better with the ocean, develop bigger teeth to bite his prey and for self-defense (since it will no longer be able to squeeze its prey because it's smaller); becoming diurnal, to make it easier to find his prey during the day, since the majority of fishes will be out on that time (behavioral adaptation); eyes adapted to see underwater.
