这项研究是第一次检查整个显微解剖的代表性的湖泊家庭Acochlidididae s.l.，属于海洋中沙无绿藻目。Strubellia paratype paradoxa（Strubell，1892）是用Amira软件从一系列半薄切片中三维重建的;最近在印度尼西亚安汶岛模式产地附近收集的其他材料通过扫描电子显微镜进行了检查。结果是严格的比较与原来的描述Kuthe的1935年。奇异龙的生殖系统是单尾的，在雄性阶段有两个异精子容器，这表明该物种是一个顺序的，前雄的雌雄同体，而不是gonochoric;一个开放的精液沟连接到一个复杂的头状交配器。两室心脏与明显的心外膜，细长的肾脏和环状肾管被解释为可能适应淡水栖息地。与来自所罗门群岛的S. oparanao sensu Wawra 1974和1988的差异进行了讨论。
This study is the first to examine the entire microanatomy of a representative of the limnic family Acochlidiidae s.l., belonging to the otherwise marine mesopsammic Acochlidia. A paratype of Strubellia paradoxa (Strubell, 1892) was reconstructed three-dimensionally from serial semi-thin sections using the software Amira; additional material recently collected close to the type locality on Ambon Island, Indonesia was examined by scanning electron microscopy. Results are critically compared with the original description by Kuthe of 1935. The genital system of S.paradoxa is monaulic, with two allosperm receptacles in the male phase, suggesting that the species is a sequential, protandric hermaphrodite rather than gonochoric; an open seminal groove connects to a complex cephalic copulatory apparatus. The two-chambered heart with conspicuous epicardium, the elongated kidney and the looped nephroduct are interpreted as possible adaptations to the freshwater habitat. Differences from S.oparadoxao sensu Wawra 1974 and 1988 from the Solomon Islands are discussed.
