How long does the skeleton/dead mans body last in the ocean depth?

Question

In old shipwrecks, did any one find a skeleton? Did anyone find any skeleton in the titanics wreckage.

Answer 1

Ocean water contains sodium which besides calcium also strengthens the bone, as far as time is concerned so it will last forever unless its destroyed or shattered to pieces, also with the temperature it is most likely frozen solid, and is even more IMPERMEABLE to any type of oxidation or destruction by bacteria.

But theres also pressure, this can break bones because high pressure, as you already know breaks even the strongest submarines, it also works for bones! higher pressure = cracking bones under the ocean!

Answer 2

Yes. Go save the world, Spider-Man!
