Does any indigenous antarctic life still exist?

From what I understand there has been a significant period of time from the point when Antarctica separated from the other landmasses to the point when glaciation made it largely uninhabitable. Enough time for evolution to create distinct Antarctic species.
Do we know if any species that spent part of their evolutionary history exclusively in post-separation Antarctica still exist today?

A bunch actually. Non-flying birds including the Emperor and Adelie penguins are found only on the antarctic coasts. 3/ species of mammals, the Leopard seal, Ross seal, and Crabeater Seal. There are a few other species of seals but those have a greater range that extends out of the continent. And also one species of insect, *Belgica* antarctica which lives in a very specific part of the continent.

There are also bacteria adapted to live in now, and a bunch of fish and marine invertebrate that don't go too far from the continent if you want to include surrounding waters.
