A marine organism is found to have very high levels of urea that would normally cause deleterious effects in most other organisms, however it has no apparent signs of ill health. It is also found to have extracellular Na⁺ and Cl^- levels lower than that of its environment. Given this evidence, what is this animal's method of maintaining osmotic equilibrium?

The marine organism maintains osmotic equilibrium through ureoosmoconforming, a process where high levels of urea are retained to balance internal and external osmotic pressure without causing harm, while also adjusting ion concentrations differently from the environment.
