Aggregata eberthi
Aggregata species occur in molluscs (e.g., A. eberthi in the cuttlefish Sepia officinalis or A. octopiana in the common Octopus vulgaris and in predators (e.g., brachyceran crustaceans). While the sexual development is proceeded in the final host (here cuttlefish), the schizogony runs inside the intermediate host (here the decapod crab Portunus ...
