Global diversity offish parasitic isopod crustaceans of the family Cymothoidae
Life cycle: The cymothoidae life cycle involves only one host (Holoxenic cycle) [23,24] and attach to fish early in life and pass through a male stage before becoming female.
Pathogenesis and clinical sign: Cymothoidae are blood feeding.
Isopods (Isopoda: Aegidae, Cymothoidae
, Gnathiidae) associated with Venezuelan marine fishes (Elasmobranchii, Actinopterygii).
and non-identified Cymothoidae
were crustaceans parasitizing A.
Prey families identified in the analysis were: Ceratopogonidae, Chironomidae, Ephemeridae, Siphlonuridae, Gomphidae and Belostomatidae (Insecta); Cymothoidae
and Palaemonidae (Malacostraca); Pisidiidae (Bivalvia); Pleuroceridae (Gastropoda) and Sciaenidae (Osteichthyes).

The parasite Paracymothoa astyanaxi presents the typical morphology of the family Cymothoidae with the latest pereopods adapted for grasping in the oral region of the fish host (Figure 2).
In the case of parasitism by Cymothoidae, the occurrence may be underestimated by the behaviour of the parasites who abandon the host and so cease swimming movements (Brusca, 1978).

Among the isopod crustaceans, species belonging to the family Cymothoidae
are of special interest, because their hosts are fishes of commercial importance.
