海螺属（海螺科，棘皮科）含有三萜苷，具有抗真菌活性。然而，真菌可以从海棠的所有器官中分离出来。1995-1996年，在俄罗斯滨海边疆区附近的日本海采集了远东海葵属植物Apostichopus japonicus、Eupentacta fraudatrix、Cucumaria japonica的菌丝真菌，并对其进行了研究。从海生真菌中分离鉴定了27种海生真菌，多数属有丝孢子真菌兼性真菌。从海胆表面分离的真菌比从内脏和体腔液分离的真菌种类更丰富。在所研究的海葵属植物中，黄瓜的真菌丰度和多样性最差。短苞枝孢菌和球孢菌是海参体腔中常见的真菌。由于其高蛋白水解活性，这些真菌可能对海棠具有致病性。研究表明，海螺碎屑虫对海底沉积物中的真菌组合有一定的影响。
Holothurians (Holothurioidea, Echinodermata) are known to contain triterpene glycosides, which show antifungal activity. Nevertheless, fungi can be isolated from all organs of holothurians. During 1995-1996, mycelial fungi from several Far-Eastern holothurians--Apostichopus japonicus, Eupentacta fraudatrix, Cucumaria japonica--were collected from the Sea of Japan near the coast of Primorye (Russia) and studied. Twenty-seven species of marine fungi, mostly facultative ones belonging to the mitosporic fungi, were isolated from the holothurians and identified. Fungi isolated from the holothurian surface were more diverse and abundant than those from internal organs and coelomic fluids. Of the holothurians studied, Cucumaria japonica was poorest in abundance and diversity of fungi. The fungi Cladosporium brevicompactum and C. sphaerospermum were common in the holothurian coelom. Because of their high proteolytic activity, these fungi may be pathogenic to holothurians. The detritovorus holothurian A. japonicus was shown to modify the fungal assemblages within the marine bottom sediments.
