魚(yú)類(lèi)的鰓與陸上動(dòng)物的肺可說(shuō)成是類(lèi)似的。
The sando's muted color palette was inspired by the typical hues of large terrestrial animals, like elephants and whales.

Why? Because fish can afford to be lazier than terrestrial animals. Fish essentially float all the time. So their muscles don't work constantly to fight gravity.
爲(wèi)什麼呢？因爲(wèi)魚(yú)類(lèi)的生活比陸地動(dòng)物“更慵嬾”。魚(yú)類(lèi)一直都浮在水中，所以它們的肌肉不用長(zhǎng)期對(duì)抗重力作用。
