Hematodinium is a type of parasitic dinoflagellates infecting marine crustacea. It would affect severely various stocks of commercial valuable crustacean fisheries worldwidely. Recently, Hematodinium was found in southeast coast of China and had caused epidemic diseases in several cultured crustaceans, such as Portunus trituberculatus, Scylla serrata, and Exopalaemon carinicauda, and was identified the causative agent of certain epidemic diseases. However, current research in China focused on field survey, pathogen identification, and diagnostics, little is known about the life cycle and transmission of this dinoflagellate. Understanding its life cycle and transmission is critical to control the spreading of the epidemic pathogen. Thereby, we review the biology and ecology of Hematodinium spp. in marine crustaceans, focusing on taxonomy, life cycle, transmission, epidemiology etc., to highlight key aspects of the pathogen in the future research and practical strategies to control the spreading of the disease.
