- Flying seabirds. Wandering albatross.
Why are spiders not found in Antarctica?
Cold water can hold more dissolved oxygen than warm water, and the oxygen content of seawater near the coast of Antarctica is especially high. So far their results seem to support the oxygen hypothesis for polar gigantism: larger sea spiders fare poorly in low oxygen water.
Are walruses in the Antarctic?
There are marine mammal species living in all the oceans – tropical, temperate, and polar. In Antarctica there are numerous seals and whales. Seals are classified with the pinniped group (seals, sea lions, walrus).

The elephant possesses a set of tusks that grow continuously throughout its life.
Where do narwhals live?
About the Species. Narwhals are found in the Arctic Ocean. Generally male narwhals have a tooth that grows into a long clockwise-spiraled tusk, resembling a unicorn horn. Narwhals, like all marine mammals, are protected under the Marine Mammal Protection Act.
Are there snakes in Antarctica?

They feed only in the water although they have been known to rock an iceberg to tip off a young seal or a penguin.
What is the biggest threat to animals in Antarctica?
Globally, invasive species such as cane toads in Australia, or kudzu (an invasive vine) in Europe can decimate the local species and ecosystems. Even the words most pristine region – Antarctica – is at risk, where non-native species are one of the greatest threats to the native plants and animals.
What is the largest land mammal in Antarctica?
