如果异形确实通过开放孔呼吸，这些孔将成为其外骨骼薄弱点，内部物质可能会因压力差而从中喷出。

Insects breathe through a network of tiny tubes called tracheae, which extend  throughout their bodies and open to the outside world through small holes called spiracles.

它们会通过扩张和收缩腹部，将空吸入和呼出腹部门，这些门是身体两侧小孔。

Oxygen enters these spiracles and diffuses directly into the tracheal system, delivering  oxygen to cells and tissues, bypassing the need for a circulatory system to transport oxygen.

You would almost think a great gun had been discharged; and if you noticed the light wreath of vapor from the spiracle at his other extremity, you would think that that was the smoke from the touch-hole.
