珠螺（学名：Lunella coronata，臺灣話：tsu-lê），臺灣澎湖當地俗稱大頭仔（臺灣話：tuā-thâu-á）、大頭螺仔（臺灣話：tuā-thâu-lê-á），是鐘螺目蝾螺科珠螺屬的一個腹足纲软体动物物种[2]。
形態描述
[编辑]The shell grows to a length of 4 cm, with conspicuous flattened, cup-like scales interspersed by small, regular rows of nodules. The colour of the shell is pale to greenish, flecked with purplish-brown markings (often encrusted with light pink coralline algae). The 螺厣 is smooth to faintly granular with pale green centre. (Richmond, 1997).
The solid, imperforate shell has a depressed-turbinate shape with a diameter greater than the altitude. It is covered with an irregular spiral series of nodules and granules, of which the subsutural series and two on the median portion of the body whorl are more prominent. The spire is depressed, dome-shaped with an apex that is frequently eroded and red. The shell contains 4 to 5 whorls, the last very large. The large 殼口 is round and iridescent within. The wide columella is flattened and excavated, deflexed recurved and somewhat channelled at its base, The inside of the 螺厣 is flat, greenish and golden, iridescent, with about 5–6 whorls and a subcentral nucleus. Its outside is convex, greenish, sparsely granulate all over.
The species is subject to a wide variation. The passage from the strongly tuberculate forms into those in which the transverse striae simply cut the lirae into diamonds or granules is made by imperceptible degrees.[3]
分佈
[编辑]這個海洋生物分佈於非洲東南部的红海海岸、马斯克林群岛及整個印度洋-太平洋海域，包括中国大陆[1]、臺灣[1]、香港。
棲息地
