成年截形椎实螺血细胞的超微结构研究表明，在不同分化阶段，伸展细胞占优势。几个圆形细胞可能代表一个独特的血细胞群体。就像L.滞水期，伸展细胞合成过氧化物酶的能力显著，过氧化物酶储存在分泌颗粒中，而在L.除了truncatulahemocytes外，内源性过氧化物酶活性也位于多泡体中。血细胞的超微结构和过氧化物酶含量似乎没有受到影响，在螺建立寄生虫。寄生虫干扰正常血细胞功能的证据是，在寄生蜗牛中发生的少数胶囊中，血细胞没有正常扩散，其过氧化物酶颗粒被吸收成多泡体。
The ultrastructural study of adultLymnaea truncatulahemocytes reveals a preponderance of spreading cells at different stages of differentiation. A few round cells may represent a distinct population of hemocytes. As inL. stagnalis, spreading cells are remarkable in that they synthesize peroxidase that is stored in secretory granules, but inL. truncatulahemocytes, endogenous peroxidase activity is also localized in multivesicular bodics. The ultrastructure and peroxidase content of hemocytes do not seem to be affected in snails with established parasites. Evidence that parasites interfere with normal hemocyte functions is that in the few capsules that occurred in parasitized snails the hemocytes did not spread normally and their peroxidase granules were resorbed into multivesicular bodies.
