''Chione cancellata'', is a species of medium-sized saltwater clam, a marine bivalve mollusc in the family Veneridae, the venus clams. This species is now understood to be strictly Caribbean in distribution. The more northern species which resembles this, which is usually called the "cross-barred venus" and which was considered to be ''C. cancellata'' for many years is now known to be ''Chione elevata''. ==Shell description== This species grows to be 1 inches across, and has a rounded, triangular shell with both strong concentric ridges and strong radial ribbing, which together form a raised crisscross pattern of ridges, hence the specific name, ''cancellata'' or cancellate. The interior of the shell possesses crenulations on its bottom edge, and like most Veneridae it has well-developed lateral and cardinal teeth on the hinge line. The shell of ''C. cancellata'' ''sensu stricto'' is quite brightly colored and patterned. (This is in contrast to the species ''C. elevata'' which usually has a grayish yellow-white exterior, occasionally with a few lavender radial stripes. The shell interior of ''C. elevata'' is usually purple.) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chione cancellata」の詳細全文を読む スポンサード リンク
