Island
wildlife:
The many accessible islands on
the western side of the Antarctic Peninsula are packed with wildlife. The islands have chinstrap, gentoo and Adelie
penguin rookeries, as well as nest sites for kelp gulls, Antarctic skuas,
fulmars, blue-eyed shags and petrels.
Weddell and crab- eater seals haul out on beaches and ice floes, and
leopard seals, armed with powerful jaws, hunt penguins close to shore. Offshore, pods of killer whales search for
seals they can tip from ice floes, and humpback, minke and fin whales feed on
enormous swarms of shrimp – like krill.
It is so cold for most of the
year that only two plucky flowering plants grow here, mainly on the western
side of Peninsula. One is a scruffy,
hardy hair grass, and the other is a pearlwort, a cushion – shaped plant that
hugs the ground and produces very small whitish flowers in summer. Primitive plant-like organisms that resist
cold and desiccation, such as mosses, liverworts, lichens and algae, make up
the rest of the flora.
Although there is a wealth of animal life in the waters around
the peninsula, and penguins breed here in their thousands, none of these
species live on the peninsula all year around.
The biggest resident land animal is a flightless midge about 12mm (1/2
in) long, and the top land predator is a tiny mite, no bigger than a pinhead,
that feeds on spring tails. Many of the
fauna species produce their own antifreeze to survive the Antarctic winter.
