Antarctic Animals – Extreme Climate Animals

antarctic animals

Welcome to Antarctic Animals! Within this site you will find information and facts about Antarctica but more specifically the Antarctic animals, such as seals, whales and birds.

When it comes to Antarctic animals, they are provided with special tools which can help them survive the extreme Antarctica weather conditions prevalent in the continent. There are many Antarctic facts for instance penguins and seals are found to possess compact body shapes and thick skins which can help keep their bodies in heat. Many animals in Antarctica have layers of fat which insulate and protect them from the extreme cold Antarctica weather. In order to protect from freezing, species of fish and insects have special chemicals in their bodies. Penguins drink the sea water and expel through nostrils as the concentrated brine.

It has been estimated that humans were found to live in this continent since the beginning of the twentieth century and for a long time they were feeling the volcanic activity. It has also been found that several invertebrates which include the largest Antarctica land animal, a wingless midge which is a centimeter in length was found to live in the continent. Lichens and moss started growing on the island after the volcanic eruptions.

More than seven hundred species of algae and phytoplankton are found to live in the Antarctic Region apart from whales, seals and other animals in Antarctica. On account of the heavy presence of whale species of different sizes and varieties including the largest whale, whale watching is becoming very prominent around the island resulting in more and more tourists arriving at the island throughout the year.

Whales are considered to belong to the family of mammals. They have lungs and breathe air like human beings and are warm blooded. They are found to possess a four chambered heart and are affectionate in taking care of their young calfs with the mother whales feeding them with milk. They are considered to be related to dolphins and are divided into two groups. Some whale species are toothed whales and others are known as baleen whales. In fact the toothed whales have rows of peg like teeth and one blow-hole. In Antarctic waters there are more than six species of baleen whales namely; humpback, Minke, Sei, blue, fin and southern right whale. Many five toothed whales can be seen in the Antarctic waters. It is quite interesting to watch the whale species moving in and out of the sea waters. Like human beings they can be found loving others and the young whale calf’s can be found following the mother whale from one direction to another. By nature, the whales are such creatures which are found to be intelligent with no natural fear of humans, in fact they like to mingle with human beings and the experience is found to be enriching and enlightening. However getting close to them can be hard at times as some can be really shy.

What Antarctic Animals Can Be Found?


Emperor penguin is one among the Antarctic animals and is the heaviest and tallest of all penguin species. It weighs around 65 to 90 pounds and can be three to four feet tall. There are several penguins in the continent namely; Chinstrap penguins, King penguins, Rockhopper penguins and Gentoo penguins.

It is found that on the outer side of the deception island where less volcanic activity has been found, there is a chinstrap penguin rookery numbering more than hundred thousand pairs. Thousands of penguins can be found moving from one to another end.


When it comes to the Antarctic whale, there are different whale species available in the continent and the blue whale is considered to be the largest whale but not only the largest whale, the largest animal on the planet! The head of humpback whale constitutes up to one third of its whole body length. The sperm whale is found to be the largest whale species of the toothed whales and its length is found to be more than fifty feet. Orca whale is called as the killer whale; however, it is said to belong to the oceanic dolphin family and is one among the largest species.


Antarctic seals are found on the continent and their blubber is two to four inches thick. It protects them from the continent’s extreme cold Antarctica weather conditions. Despite seal facts that they are found to be as heavy as 250 pounds, they can swim at a speed of 11 mph. While seals swim in the water they close their ears so that water is resisted from entering into their bodies.

Other Antarctic Animals

Apart the mentioned Antarctic animals above, Arctic Tern is found to be a species of bird and it is one of the three Antarctic animals that live all year round on the continent. The head of the Arctic Tern is black in colour, it has a white body and its wings span is about four feet. Crustaceans; namely crabs, sea spiders and shrimps are other life forms that are available in Antarctica and certain species of fish namely; the Antarctic cod, robber fish, ice fish, ray tailed fish, crocodile fish and dragon fish are also some marine life species found on the continent.

Antarctica Weather

There are seven continents on the earth, However, when it comes to human living, all continents are found to have different weather conditions and while some are conducive and not conducive for human living on account of extreme cold and hot climates.

While the continents like America, Asia, Europe, Australia and Africa are found to have climates suitable for human beings, the other continents namely; Greenland and Antarctica have extreme cold climate at all times. Only vegetation possible in Antarctica is tundra. The Antarctica weather produces a very cold and harsh climate for all Antarctic animals.

Amongst the seven continents of the earth, Antarctica is considered to be the coldest and driest. On account of the harsh Antarctica weather prevalent in the continent, the continent is not inhabited by human beings. However, there are certain Antarctic animals which survive despite such difficult Antarctica weather conditions and tourists from several countries in the world are eager to visit the continent in order to have a look at those Antarctic animals.

The Antarctica weather produces an outstanding and extreme climate and holds the world record for coldest record climate. A thick, solid sheet of ice covers the entire area being on average a remarkable 7000 feet thick! Interestingly the Antarctica also contains more than seventy percent of the world’s fresh water.
