Nurse sharks even nap on the seafloor; however, they use a form of ram ventilation in which they draw in water through nostril-like structures near the eyes, called spiracles, and force it out through the gills.

铰口鲨甚海底打盹；不，它们采用的是一种特殊的撞呼吸，即通眼睛附近的鼻孔状结构（称为鳃裂）吸水，然后用鳃将水排。

The moment you grab the shark's gill slits, it is absolutely going to spit you out and try to get away.

一旦你抓住鲨鱼的鳃裂，它绝对把你吐来并试图逃脱。
