描述
它有寬而彎曲的肋骨,導致它被稱為“義齒蛤”。 兩個殼體之間的之字形連接阻止了粗糙的污垢和碎屑進入殼體並損壞其柔軟的身體。像現代牡蠣一樣,它生活在淺海岸水域,包括潮間帶(高潮和低潮之間的區域),並以從海水中濾出的食物顆粒為食。
Descriptions
It has wide, angled ribs that have led to it being called the ‘denture clam’. The zig-zag join between the two shells stopped coarse dirt and debris entering the shell and damaging its soft body. Like modern oysters it lived in shallow coastal waters including the intertidal zone (the area between high and low tide) and fed on food particles that it filtered out of the sea water.
