Bivalvia, a class of Mollusca, is an animal group with a body plan covering the soft internal body with a pair of left and right shells. However, it is difficult imagining their internal structures and body plan. In this article, we focused on understanding the body plan of the clam using paper craft to enhance observation and dissection in order to highlight biological diversity for students. In questionnaires regarding the body plan of the clam, Ruditapes philippinarum, approximately 40% of teacher training students understood that clams possess anterior-posterior, dorso-ventral and left-right axes, but found it difficult to draw each axis. In particular, there was confusion concerning the fact that the clams possess a pair of shells along the left-right axis. Additionally, as the body plan of clams is very different from that of mammals, many students did not understand the functions of the exhalent and inhalent siphons. Therefore, we created a paper craft model of the clam to demonstrate its body plan in this study...
