Why it evolved

The sharp shifts in water salinity on JoJoLands exert strong osmotic pressure, favoring individuals with enhanced osmoregulatory capabilities. This descendant has evolved specialized organs to actively control internal salt balance and a thickened, less permeable integument to minimize water loss or gain. This adaptation comes at the cost of reduced bioluminescence intensity, as energy is diverted to maintaining cellular integrity, and a shift to internalized gonads to protect reproductive organs from osmotic shock. These changes slow its metabolic rate, making it less active but more resilient to the fluctuating environmental chemistry.
