Florida—Video—The First Ever Virus Disease in Tropical Lobsters

 

This three-minute video describes the first-ever virus disease found in tropical lobsters.  Discovered in the Caribbean spiny lobster (Panulirus argus), it has been named “Panulirus argus Virus One”, or “PAV1”.  It affects P. argus through much of its range and expresses itself by turning the white shell on the bottom of the tail to pink.  Also, the blood in affected animals turns from a clear amber/gray to milky white.  At this stage, the lobsters almost always die.  Larvae born to females with PAV1 don’t break with the disease, but they do carry it to new locations and may break with the disease when they metamorphose into larger animals.  PAV1 has been confirmed off the Yucatan coast of Mexico and in Belize, Guatemala, Cuba, southern Florida, the Dominican Republic, Puerto Rico and the British Virgin Islands.  It has not been found in Nicaragua, Montserrat, Dominica or the Cayman Islands.
