First Observations of Tumor-Like Anomalies in Planktonic Copepods in the Crimean Coastal Waters
Journal: Journal of Siberian Federal University Biology
Year: 2016

In copepods from zooplankton samples collected in coastal waters of the Crimea near Sevastopol in 2011-2012, external tumor-like anomalies (TLA) were found. These anomalies are presumed to be parasitic protists (perhaps dinoflagellates of the family Ellobipsidae) or the hernias induced by injuries. Percentage of specimens with TLA varied, depending on the species, from 0.2 to 20.9 %.
