Just to put it out there, MikeAdams#367 just provided me with the following information:

Typical cells are about 70% water, while jellyfish are typically listed as being 95% water. Assuming the non-water components are approximately the same in make up in both cases, then the jellyfish would be about (with rounding errors): Oxygen 85% Hydrogen 9.5% Carbon 3% Nitrogen 1.5% calcium 0.2% phosphorus, 0.15%  potassium 0.06  sulfur 0.04  sodium 0.02  magnesium 0.01 + many trace elements
