Gross and Microscopic Observations on Some Biota from Deep Water Dumpsite 106
Euphausiids were infested on the appendages with phoronts of an apostome ciliate and also had foci of melanization in the gills. The isopod, Idotea, showed patchy lack of pigmentation, particularly in the telson, and edematous gills. Heteropod mollusks had larval cestode infestions, neoplasialike lesions, and other cell abnormalities. Examination of leptocephali revealed possible traumatic lesions and developmental anomalies. Microbial testing for the presence of mutagens promises to be a very useful method for monitoring pollution in the ocean.
