For animal and bird lovers, there is plenty of action in the form of penguins, sea birds, swallows, skua and fur sea lions (a type of seal).

Antarctica is home to many seal species such as this fur seal. Its large eyes are designed to seek out prey in dim waters and are a slightly different shape to a land mammal's.

Dean Miller, an Australian fur seal biologist, was the first person to spot the large white object floating past Macquarie island in the far south-west corner of the Pacific Ocean.
