to my knowledge, it is some kind of sea creature.
you know what is interesting, that the sea holds so many mysterious things that wash up shore.
for example, the Little Merm- j/k
but I mean, there have been reports of macro creatures just sitting on beaches, dead. like 50 ft. long squids. not Ursulla's remains, they're real~
Antartica... has these fish that swim in freezing liquid water, they produce the same chemicals found in anti-freeze, the stuff we have in our cars. I think it's called something like glycerin-protein. But it helps keep their blood from freezing in the artic waters.
crazy, if we extracted this chemical from the fish, studied it, and safely implemented this stuff into ourselves, we'd be cold blooded.
don't go drinking anti-freeze though, lab scientists usually do that for us in studies, j/k
