소금은 물을 흡수하므로, 체액과 바닷물의 염분 차이에 따라 바다 생물은 부풀거나 쪼그라든다.
Because salt absorbs water, sea creatures swell or shrink depending on the salt difference between their body fluids and seawater.

📖 본문 보기
Even though sea creatures live in it, they still need to take in water for their bodies to function properly. They just need to get rid of any extra salt it might bring with it. Salt absorbs water like a sponge. If you put a tiny mountain of salt on a small plate, then add enough water to the side, making sure an edge touches the salt, the salt will absorb the water. Now you have a pile of wet salt. Notice that it has increased in size. The same principle applies to sea creatures. If the body fluids in a sea animal are saltier than the seawater it lives in, then the extra salt in the creature’s body will absorb seawater. This can cause them to swell up. On the other hand, if the amount of salt in the seawater is higher than the amount of salt in the body fluids of a sea animal, the extra salt in the water will draw fluids out of the creature’s body, causing it to dehydrate and shrink.
🏹 시은의 질문 · “한 문장으로 줄이면?”
Salt pulls in water, so a sea animal swells if its body is saltier than seawater and shrinks if the seawater is saltier.
소금은 물을 끌어당기므로, 몸이 바닷물보다 짜면 바다 생물은 부풀고 바닷물이 더 짜면 쪼그라든다.
