New Temperature Record for a Eukaryote

I thought this was interesting: https://www.cell.com/cell/fulltext/S0092-8674(26)01016-0

An amoeba has been found that functions at temperatures up to 63C. Hitherto only thermophile bacteria and archaea have been found that can tolerate such temperatures. It seems the amoeba relies on some biochemical features similar to these bacteria and archaea, the most striking of which is proteins with a net +ve charge. Apparently the repulsion between strands that this creates can inhibit the clumping and denaturing that might otherwise occur at high temperatures. They say it looks as if this similarity is due to convergent evolution. So presumably it has not arisen by some kind of horizontal gene transfer.

What I found myself wondering is how this compares with tardigrades. These are multicellular eukaryotic animals that seem remarkably resistant to extreme conditions. Has anyone done work on how these creatures manage it?
