在佛罗里达[美国] Ecarpment 3266 m深处的盐水渗漏中，发现了一种复杂而极不寻常的真核微生物，它能穿透并去除深海贻贝的角质层。这些盐水渗漏支持chemolithoautotrophic氧化还原社区类似于那些已知的太平洋热液喷口。这种微生物分类学上的亲和力未知，是丝状和多核细胞的，有一个简单的质膜，没有细胞壁。它形成直径为8-15 μ m的分枝隧道的匍匐辐射系统。隧道的表面由螺旋状组织的鳞片状凹陷雕刻而成，这些凹陷是生物体在去除角质层的过程中留下的疤痕。在隧道的末端以不连续的碎片（扇形）去除角质层。这种生物在三个大西洋深海氧化还原群落中被发现，但在太平洋的类似群落中没有发现。
A complex and highly unusual eukaryotic microorganism was discovered to be penetrating and removing the periostracum of deep-sea mussels from the Florida [USA] Ecarpment brine seeps at a depth of 3266 m. These brine seeps support a chemolithoautotrophic redox community similar to those known from Pacific hydrothermal vents. This microorganism of unkown taxonomic affinity is filamentous and coenocytic, with a simple plasma membrane and no cell wall. It forms prostrate, radiating systems of branched tunnels, 8-15 .mu.m in diameter. The surface of the tunnels is sculptured by helically organized, scale-like depressions, which are left as scars in the process of periostracum removal by the organism. Periostracum is removed in discrete pieces (scallops) at the ends of the tunnels. This organism has been found at three Atlantic deep-sea redox communities, but not in similar communities of the Pacific.
