Which outcome occurs when a marine fish fails to properly maintain blood osmolarity in saltwater?

💡 Explanation

When osmolarity regulation fails, water diffuses out of the fish's cells because of the surrounding high salinity creating cellular dehydration that reduces metabolism. Therefore, cellular dehydration dominates, rather than gill or kidney impact, which require dedicated mechanisms for ammonia excretion or protein catabolism respectively.
