Which process acutely exacerbates dehydration in a freshwater teleost when exposed to a hypertonic solution?

💡 Explanation

When a freshwater fish enters saltwater, osmotic pressure gradients induce increased cutaneous water diffusion out of the fish because water moves from a hypotonic to a hypertonic medium through osmosis. Therefore water loss increases, rather than ion absorption, reduced kidney pressure, or altered gas exchange, all of which regulate internal ion balances under different conditions.
