3. Adélie Penguins
The Adélie penguins are another species of penguin you’ll find in Antarctica. They are considered the most southerly distributed of all penguin species and are typically found on pack ice along the Antarctic continent and subantarctic islands.
Small but mighty, Adélies weigh an average of 5 kilograms and stand less than a meter tall. Yet, despite their smaller size, they are bold and highly social and are among the most entertaining penguins you get to observe in the wild.
Adélie Penguins breed from November to February, and visiting a rookery during this time is an amazing experience. These breeding colonies are massive, often containing up to half a million birds! You’ll likely hear their loud calls and catch the unmistakable smell of the rookery before you even spot them.
During the breeding season, the male Adélie penguins build pebble nests slightly elevated above the ground to protect their eggs from flooding. This pebble-gathering process often leads to amusing squabbles, as stealing stones from a neighbor’s nest is quite common.
Once the eggs are laid, both parents share the responsibilities of incubating and rearing the chicks, which fascinates scientists due to their cooperative parenting and unique nesting behavior.
For the best chance of seeing Adélie penguins in their natural habitat, visit the Ross Sea region, home to several large Adélie penguin colonies. Cape Royds and Cape Bird on Ross Island are best known for their rookeries.
Another excellent destination for seeing Adélie penguins is East Antarctica, where colonies can be found near the Mawson Coast and along Commonwealth Bay.
Expeditions to these areas often include landings near penguin rookeries, allowing you to observe their lively and charismatic behaviors up close.

4. Antarctic Krill
Although Antarctic krill may be the smallest species among the Antarctic wildlife, they are also the most vital.
These tiny, shrimp-like crustaceans are the cornerstone of the Antarctic food web, providing sustenance for whales, seals, penguins, fish, seabirds, and other Antarctic animals.
They are about 6 centimeters long and gather in massive swarms, sometimes stretching for miles and containing millions of individuals. This incredible biomass makes them one of the most keystone species on the planet.
Antarctic krill are remarkable species due to their ability to survive in such harsh conditions. They feed on phytoplankton and algae that grow under sea ice, using specialized feeding appendages to scrape food from ice surfaces.
During the long, dark Antarctic winters, they can shrink their bodies and survive on minimal resources, a unique adaptation that allows them to survive in extreme environments.
The best way to spot krill is to observe their predators in action. Humpback whales, minke whales, and leopard seals can often be seen feasting on krill-rich waters in the southern ocean.
Areas like South Georgia Island and the Antarctic Peninsula are the best spots to see Antarctica’s wildlife, which mainly depends on krill.
If you’re lucky, you might even see krill themselves, especially when their swarms turn the Antarctic waters pinkish-red.

5. Elephant Seals
The Elephant seals are the largest seals in Antarctica and one of the most thrilling animals to encounter during your Antarctic expedition.
These Antarctic animals are massive, with males weighing 1,500 to 3,700 kilograms! Meanwhile, female Elephant seals are significantly smaller, ranging from 600 to 800 kilograms.
The striking size difference between the sexes, known as sexual dimorphism, is so pronounced that females are sometimes mistaken for juveniles when seen alongside the enormous male elephant seals.
Elephant seals are highly adapted to their environment. They are exceptional divers, capable of plunging to depths of 500 meters, and sometimes even deeper, staying submerged for up to 20 minutes while hunting for squid and various fish species. Their ability to thrive in the icy waters of the Southern Ocean makes them a remarkable sight.
To see Elephant seals in their natural habitat, head to sub-Antarctic islands. They gather in large colonies along the beaches to breed and molt.
South Georgia Island is one of the best places to observe these impressive animals up close, especially during the breeding season when males engage in dramatic battles for dominance.
Other excellent locations to spot them include the Falkland Islands, Macquarie Island, and the South Shetland Islands.
While the Elephant seals spend much of their time on land during specific seasons, they rely on the surrounding sea ice and frigid waters for feeding.

9. Orcas (Killer Whales)
The killer whale, or orca, is the largest species of dolphin and one of Antarctica’s most awe-inspiring predators. Despite their name, killer whales are social creatures that often travel in pods and exhibit incredible hunting behaviors.
With an estimated global population of 100,000, you can find killer whales in all oceans across the globe. However, many are in Antarctica, making the southern continent the ultimate destination for observing these marine mammals in their natural habitat.
Recent research by NOAA identifies four distinct types of killer whales in Antarctica: Type A, Type B, Type C, and Type D.
Each type has unique physical traits, behaviors, and prey preferences. Type A orcas are larger and primarily hunt minke whales. Type B, also known as “pack ice orcas,” specializes in hunting seals along the edges of sea ice.
Type C orcas, the smallest of the group, feed mostly on fish and are often found in larger pods. Meanwhile, the elusive Type D orcas, with their distinct rounder heads, are rarely spotted.
The Antarctic Peninsula is one of the best places to see killer whales, particularly during summer when the sea ice recedes, and marine life flourishes.
Places like the Ross Sea and the Weddell Sea also offer excellent opportunities to spot orcas against the breathtaking backdrop of icebergs and glistening Antarctic waters.
