Penguins are not hunted by the Eskimos, because Eskimos live in the North Pole region, while penguins live in the South Pole region. It’s too far to paddle so the energy gained by consuming the meat of a penguin would not be enough to paddle that far and back in the North Pole.
Eskimos live in the Arctic which is the North Pole region, and the penguins live in the Antarctic which is South Pole region, they stay on the opposite sides of the Earth. Eskimos live near or in the Arctic circle in the northern hemisphere. Penguins are found on Antarctica and nearest islands.
