Expanse of ice? Yes. Barren? Only kind of. Yes 99% of the continent is icy leaving only one 1% available for plants but! On that one percent, 100s of different unique species of mosses, lichens and other plants are crammed in. There's even two flowering plants, Antarctic hair grass (Deschampsia antarctica) and Antarctic pearlwort.
These moss beds are like a micro forest that is bursting with unique, mostly microscopic, life.
Penguins are, of course, the most common bird on the continent, but they're not the only ones. Albatros are (relatively) common in the region and lay their legs on the sub-antarctic islands.
Petrel birds can be found all over the coastal regions, while the south polar Skua can be found all over the continent and has been sighted at the pole itself.
Other species of bird, mostly found in the islands, include gulls, turns, cormarants, sheathbills and there's even a type of fresh water duck on South Georgia, the Soth Georgia Pintail.
And all of this isn't even talking about the amazing range of seals, whales, fish, squid, and krill that frequent the surrounding waters. It's easy to look at the aparrently barren wasteland of what is technically the world's largest desert and only see the endless night, but in doing so, you miss the incredible, diverse, and unique ecosystem. It's not an equatorial rainforest or a vast meadow, but, like every other desert, Antarctic is bursting with life
