Amoebophrya ceratii (Koeppen) Cachon 1964

A = Ceratium with the trophont; B = Early stage in Pentapharsodinium; C=Mature trophont in a gymnodinioid species; D = Early stage in Actiniscus; E&F = Trophont in epifluor. microscope; G = Vermiforme stage (flagella=arrowheads). A-D and G (DIC); G=In Lugol


Life-form: Parasite

Size: .

Resting spore:

Note: Parasite in the cytoplasm or nucleus of many different species of dinoflagellates. A. ceratii may represent a cluster of relatively host-specific species according to Coats et al. (1996).

Distinctive features: The mature trophont resembles a classic beehive in shape

Distribution: Widely
