There are several species of seals and penguins that live on land in Antarctica, while whales, fish, and krill inhabit the surrounding southern oceans. The six main seal species that reside in Antarctica make up the majority of the world's seal population. Many Antarctic animals, such as fish and insects, have natural antifreeze proteins that allow them to survive in subzero temperatures. Birds also retain heat through compact bodies, thick skin, and insulating feathers.

1. ANIMALS
There are a lot of sea animals in Antarctica-
whales, fish, and krill (small crustaceans
like prawns). The only land animals in penguins
Antarctica are penguins and seals (and people).

2. SEALS
Only six species of seals live in Antarctica-
elephant seals, Antarctic fur seals, crabeater
seals, leopard Seals, Ross seals, and Weddell
seals. However, these six species make up the
majority of the world's seal population. With
no natural land predators, such as polar bears
or man, Antarctic seals behave much differently
than northern seals, showing little fear of man.

3. FISH AND INSECTS
Some animals, like many fish and insects, have
special chemicals in their blood (natural antifreeze
proteins) that keep them from freezing. Many
animals (like penguins and seals) have a compact
body form and thick skin to help retain body heat.
Birds also have waterproof plumage (feathers) and
downy insulating feathers.

4. There are very few species
of fish in the Southern
Ocean. The channichthyidae
family, also known as white-
blooded fish, are only found
in the Southern Ocean. They
lack haemoglobin in their
blood, resulting in their
blood being colourless.
