Antarctica Animals
There are many different animals in Antarctica like whales. The blue whale is the biggest whale on earth. It is so big it is as big as a dinosaur and its heart is as big as a car. The killer whale [orca] is mostly graceful in the water. Whales have no teeth and its brain weighs 20 pounds. A sperm whale head is the biggest head on earth and sperm whales are meat-eaters. The name of a male whale is a bulls and the name of the female is a cows and the babies are called calves and the only food they eat is squid.
Seals eat shrimp ,crab ,clams ,snails ,cop even penguin pups. Seals have 2-4 inches babble and also seals are warm-blooded. Male seals are called bulls and female are called cow and their babies are called calves. Seals are clumsy on the land but very graceful in the water. The number of leopard seals has dropped by 80 percent. Seals may be clumsy on the land but in the water they go up to 11per hr speed.
The Emperor penguin weighs 32kg and 1.3m tall. Penguins eat fish, squid and krill. It goes underwater to get its food. It’s the only penguin to lay eggs and rear its young.

Australian conncetions
Sir Douglas Mawson led the Australasian Antarctic Expedition in 1911 to 1913. He also led another research team from 1929 to 1931
.
Sir Douglas Mawson first arrived to the Antarctic the icy shores in 1907. He was with British explorer Sir Ernest Shackletons’s expedition to find the South Pole in 1909.
Sir Mawson returned to Australia in 1911 to raise money to start Australia’s first expedition. The 1911 expedition was first and most serious scientific expedition undertaken during the heroic eras (which were the first 25 years in the 20th century described by Antarctic historians as the heroic era of Antarctica exploration.
The group conducted magnetic, biological, geological and astronomical studies and a huge amount of the scientific material over the two year expedition. The work was published in 1947 with 22 volumes of scientific reports. Sir Douglas Mawson built a timber base camp at Cape Denison in 1912, it is still being used today.
In 1956, Syd Kirby was 21, just out of the university and joined a 15 month expedition to Antarctica. At that time 85% of Antarctica was not explored. The field trips would take sixteen hours a day, four to five hours to set up and take down the camp. One trip in the day light of Antarctic summer Kirby and his companions went for a thirty hour day.
They are four permanent Antarctic bases for modern explorers, in planes instead of dog sleds. An Australian team has just returned from a major international field operation using light planes and using seismic sensors to map a mountain chain buried under 4km of ice in the heart of Antarctica. Information about the behavior of the ice sheets millions of years ago will help predict how they will respond to climate change and the likely rise of sea levels world wide.
The scientists hope, by studying the million year old ice, to give us the best clues to climate change. Part of the project was to set up a weather station on the summit of Dome Argur, 4093 meters above sea level, the coldest place on Earth. We are lucky to have Australian explorers who want to go to Antarctica to work out how they can change our environment for the better.
