Explanation:

Both emperor penguins and Weddell seals are adapted to extremely cold and harsh Antarctic environments. Emperor penguins have thick feathers and a layer of blubber for insulation, and Weddell seals have a thick layer of blubber to keep warm in cold waters. Gentoo penguins also live in cold - water regions but are not as adapted to the harshest Antarctic conditions as emperor penguins. Blue whales, translucent fish, krill, and amphipods do not have the same level of adaptation to extremely cold and harsh terrestrial - like environments in the same way as the first two.

Emperor penguin, Weddell seal
