Elephants Better Beat The Heat Or Else 大象最好打敗炎熱——否則可能一命嗚呼！
◎李信漢
With a relatively small surface area to body volume, elephant heat dissipation is limited to the point where extended exertion in the heat can be fatal.
由於大象的身體表面積和體積比相對較小，所以散熱能力有限，長時間在炎熱天氣下活動可能會一命嗚呼！
When summer hits, I dread jogging outside. But a study finds that elephants can be in true danger in the heat.
當夏日熱浪來襲，我不敢在外面趴趴走。但一項研究發現，大象在高溫下真的會陷入險境。
As creatures get bigger, they have smaller surface area to body volume ratios. Fully grown Asian elephants thus pack a lot of mass into a body with a relatively small surface area. And surface are a limits how much body heat you can dissipate.
當生物體積越大，牠們的表皮面積相對於身體體積的比例就越小。成年亞洲象因此在體內囤積大量質量，但表皮面積相對較小。而表皮面積限制你可以排出多少熱量。
