I never had anything wrong with my heel except the time the sting ray stung it when I stepped on him when swimming and paralyzed the lower leg and made the unbearable pain.

我的脚后跟从没出过毛病，除了有一次在游水时踩着了一条海鳐鱼，被它扎了一下，小腿麻痹了，痛得真受不了。

The lack of eye organs also seems to indicate that this is a strong possibility, and its thought that xenomorphs track their prey by scent and electroreception much like a hammerhead shark and many sting rays.

眼部器官的缺失似乎也表明这是一种很强的可能性，它认为异形体通过气味和电接收来追踪它们的猎物， 就像锤头鲨和许多黄貂鱼一样。
