Lymphocystivirus cause mass mortality events like megalocytiviruses and ranaviruses, fish with lymphocystis exhibit grossly visible papilloma-like skin lesions which substantially reduce their commercial value. No vaccines are currently available for lymphocystis viruses. Group: dsDNA The genus "Lymphocystivirus" has only one species: "Lymphocystis disease virus 1" (LCDV-1), but Lymphocystis disease virus 2 (LCD-2) is another virus that has been proposed as a second member. LCDV-1 infects European flounder "Platichthys flesus" and European plaice ("Pleuronectes platessa"). LCDV-2 infects the common dab ("Limanda limanda"). A third species Lymphocystis disease virus C has also been proposed based on the relative lack of sequence similarity of
Elassoma evergladei 115 to 500, increasing with the fish's size. The fish has variable color and form. Its body is generally colored brown with darker spots. The fish has several rows of dark red spots on its dorsal and anal fins. "Nonbreeding" fish may have light streaks, mottling, or blotches. Females of the species in general are colored brown on their backs with mottled brown and cream/white coloring underneath, or they may be reddish brown. The females have no markings. "Breeding" males are colored black with iridescent blue spots. Males have black fins with or without brown spots. Male bodies may be
