اختبار إلكتروني: Reading Comprehension Assignment

Antarctic penguins are remarkable birds that have developed unique physiological and behavioral adaptations to survive in one of the world's harshest environments. Out of seventeen penguin species, only four, such as the Emperor and Adélie penguins, live in the Antarctic year-round. To conserve body heat during the brutal winters, these penguins congregate in massive communities of up to 6,000 individuals. They also possess specialized complex nose tubes that help reduce heat loss from the body. Their reproductive behavior is equally specialized; for instance, the female Emperor penguin entrusts her single egg to the male while she travels to the sea for several weeks to hunt for food, showcasing a critical survival strategy in the freezing southern climate.
