The karyotypes of Biomphalaria tenagophila collected from Rio de Janeiro, Brazil were studied using the air-drying method. Somatic cells of this species had 2n=36. The 18 chromosome pairs were identified and classified into 3 groups. The diploid cell has 7 pairs of metacentric, 8 pairs of submetacentric, and 3 pairs of subtelocentric chromosomes. Observed chromosomes ranged from 2.4 to 6.4 µm, and the total length was 122.3 µm. This is the first report on the chromosome of B. tenagophila.
采用空气干燥法对采自巴西里约热内卢的嗜气管双脐螺的核型进行了研究。该物种的体细胞具有2n = 36条染色体。18对染色体被识别并分为3组。二倍体细胞有7对中着丝粒染色体、8对亚中着丝粒染色体和3对近端着丝粒染色体。观察到的染色体长度在2.4至6.4微米之间，总长度为122.3微米。这是关于嗜气管双脐螺染色体的首次报道。
