鲍鱼的头？九头鲍鱼怪！！

鲍鱼的单位一直是个谜。。。直到被朋友踩呀-踩呀-踩--呀---踩。。。

其实啊， 鲍鱼 abolone，同鱼毫无关系，倒跟田螺之类沾亲带故。它是海洋中的单壳软体动物，只有半面外壳，壳坚厚，扁而宽，形状有些像人的耳朵，所以也叫它"海耳"。螺旋部只留有痕迹，占全壳的极小部分。壳的边缘有9个孔，海水从这里流进，排出，连鲍的呼吸、排泄和生育也得依靠它。但头并不是孔啦！

十頭即指一斤內有十個；两头就是一斤两头咯。頭數越少，鮑魚越大，亦越昂貴。須注意香港與中國內地之「斤」定義有別，在 香港一斤為600公克、中國內地一市為500公克斤，同稱「十頭」之鮑魚於內地會較細小，不少港人因此誤會內地商店欺騙顧客。
