Hematodinium perezi

Species of single-celled organism

Hematodinium perezi is a pathogenic dinoflagellate parasite that infects crustaceans, including the Blue Crab and Norway Lobster and has been observed to have a significant impact on crustacean fisheries. Infected crustaceans frequently show signs of weakness and lethargy, and often die due to stress-related handling from fishing as well as metabolic exhaustion due to reduced feeding. This parasite is known to be quite transmissible between various crustacean hosts.
