<< review queue entry 56844 - submitted by 'richwarm' >> Compare B ~ http://baike.baidu.com/view/742128.htm with Wp ~ "Generally, arms have suckers along most of their length, as opposed to tentacles, which have suckers only near their ends. Barring a few exceptions, octopuses have eight arms and no tentacles, while squid and cuttlefish have eight arms and two tentacles." Also Wp @ 觸手 觸手演化而成的另外器官稱為觸腕或稱頭足，學名為tentacular arm；該器官指「鬚狀有環狀吸磐的肢臂」，為烏賊和章魚等生物所俱有之肢體，原為生於頭部之足部經演化而成，功能為運動及感覺等方面。觸腕數量通常是複數，例如章魚有四對，烏賊有五對，觸腕前端有吸盤，能吸附物體，也有感覺神經能偵測外界變化，但部分翻譯書籍，會將觸腕、觸角(常見於指蝸牛頭頂前端之凸出部份，用於感覺外界變化)或是觸手混用，即把觸腕視為觸手，但觸腕為觸手所演化出來之構造，故一般較嚴謹之生物學書籍是用觸腕來表示此演化後的肢體。 |
