They are marine snails, and are part of the large class Gastropoda. There is only one genus in the family Haliotidae, and about four to seven subgenera. The taxonomy of the family is still somewhat confused. The number of species recognized world-wide ranges from about 100 to 130 (due to the occurrence of hybrids). Abalone shells have a low and open spiral structure, and are characterized by several respiratory holes in a row near the shells outer edge. The innermost layer of the shell is composed of nacre or mother-of-pearl, which in many species is highly iridescent, giving rise to a range of strong and changeable colors which make them attractive to humans as a decorative object. Abalone are also called ear-shells, ormer in Jersey and Guernsey, perlemoen in South Africa, and pāua in New Zealand. The meat of abalone is considered by many to be a desirable food. 九孔小鮑魚Haliotis diversicolor 生長百態 九孔小鮑魚Haliotis diversicolor生長百態 分布於日本房總半島到九州、朝鮮半島、中國南部沿海、香港及臺灣等暖海流域等地。 棲息於潮間帶至數十公尺深的岩礁縫隙，喜有波浪衝擊，水質清澈的環境。以藻類為主食，雌雄異體，體外受精。在臺灣又稱為「臺灣鮑」則分布於北海岸、東海岸、屏東的恆春半島及澎湖群島。?九孔於1979年即告繁殖成功，而初期養殖業於臺灣北部潮間帶開始挖九孔養殖池，利用潮汐進退供水養殖，之後臺灣省水產試驗所從事九孔養殖技術之開發研究，並分別成功開發九孔陸上養殖法、陸上九孔單層養殖新法與改良深水立體事業養殖技術，台灣沿海地區以及澎湖七美均有養殖，因此於1995年臺灣九孔產量大增。 產量1,800噸到2,500噸之間，產值9～15億新臺幣，出口值達新臺幣30多億。 九孔，小鮑魚Small
