How Arctic Wildlife Differs from Antarctic

While the north and south poles share certain characteristics, they are also remarkably distinct. Both regions are cold and dry, yet each has its own unique terrain and climate. The Antarctic is particularly harsh and inhospitable, with only two native vascular plant species, whereas the Arctic tundra supports a wider range of fauna due to its relatively warmer temperatures and greater plant diversity. Here are some of the animals you can find in the Arctic compared to the Antarctic.

Animals in the Antarctic

Approximately 98% of the south pole is covered in ice, making survival challenging for most life forms on the continent. The absence of rivers and vegetation further contributes to the region's inhospitable nature. However, wildlife can still be observed in certain areas, particularly along warmer coastlines where densely populated colonies thrive. The limited plant life means there are few herbivores, but the sea provides sustenance for various creatures that live on land. Common Antarctic animals include:

  • Emperor Penguins: The largest penguin species, standing up to four feet tall and weighing as much as 90 pounds.
  • Southern Elephant Seals: The largest of their kind, with males weighing up to 8,000 pounds and reaching lengths of 15 feet.
  • Leopard Seals: Known for their distinctive spotted appearance, these predators feed on fish, penguins, and even seal pups.

Life on the Arctic Tundra

In contrast to the Antarctic, the Arctic supports a wide variety of flora and fauna. Instead of a solid ice sheet, much of the Arctic is covered in permafrost—a thick layer of frozen soil. While this permafrost prevents some plants from growing, many others thrive in this environment. The treeless tundra is home to nearly 2,000 species of smaller shrubs, sedges, grasses, mosses, liverworts, alpine-type flowering plants, and lichens. Rivers flowing through the region also help sustain life. The Arctic's more forgiving climate allows for a diverse range of animals, including:

  • Polar Bears: The largest bear species, weighing up to 1,500 pounds and primarily feeding on seals.
  • Musk Ox: Grazing animals that have been nearly hunted to extinction but still have small populations in the Arctic tundra.
  • Reindeer: These animals also inhabit the tundra and travel great distances throughout the year.
  • Narwhal: Known for its single horn, this creature feeds on fish, squid, and shrimp.

The North Pole and the South Pole, while sharing some similarities, are vastly different in many respects. The Antarctic is cold and unforgiving, home to only the hardiest sea mammals, whereas the Arctic can support more herbivores and land-based wildlife. Despite the extreme conditions at the Earth's poles, an impressive level of biodiversity can be found in both regions. Photo credit Noah Holm / Unsplash

The Plants of Antarctica

Surviving in Antarctica is a monumental challenge for any plant. The extreme cold, limited sunlight, scarce moisture, poor soil, and short growing season make it nearly impossible for most flora to thrive. Yet, some plants have adapted to these harsh conditions and have managed to flourish where others cannot.

South Georgia in Spring

What a fantastic time to be in South Georgia! Perhaps the best time of the year! The wildlife is abundant, and the light is simply magical for photography. Kings, Gentoos, Chinstraps, and Macaronis are all present along the shorelines. Elephant and Fur seals are also plentiful! Wandering albatrosses are welcoming their newly hatched chicks, while the non-breeders are actively engaged in their courtship rituals, practicing a ceremonial dance. Light-mantled, Sooty, and Grey-headed albatrosses are still feeding their fluffy chicks, as are the Giant petrels. We've been fortunate with the weather, finding ourselves in the right place at the right time to succeed in all our landings and zodiac cruises so far.

Living the Antarctic Dream

From October to March, during the Austral summer, thousands of breeding gentoo, Adèlie, and chinstrap penguins flock to the Western Antarctic Peninsula to rear their chicks and feast on krill before the harsh winter arrives. Alongside the penguins, field biologists from around the world gather to study these habits for conservation research. Observing these animals is one thing, but residing in an Antarctic field station for an entire breeding season is another. One particular field camp on King George Island, managed by American scientists, has perfected this Antarctic lifestyle and has thrived for over 30 years.
