| 描述 腹足綱是軟體動物門中最大的綱。腹足綱動物有肌肉發達的足部，眼睛，觸手和由許多細小的牙齒組成的特殊的類似銼刀的進食器官（小齒）。大多數腹足動物的殼呈螺旋形或圓錐形，在某些物種中可能會大大減少，或者完全消失。腹足綱動物在寒武紀早期演化，但是自古近紀以來，腹足綱動物已經成為最常見的軟體動物，棲息在水生和陸地環境中。 | Description Gastropods (formally Gastropoda) make up a large group (a class) of molluscs. They have a muscular foot, eyes, tentacles and a special rasp-like feeding organ (the radula) composed of many tiny teeth. Most gastropods have a coiled or conical shell, which may be extremely reduced in some species or lost entirely as in slugs. Gastropods evolved early in the Cambrian, but since the Palaeogene they have become the most common of molluscs, inhabiting aquatic and terrestrial environments. |
