 Comment from narcose29
Cet animal me semble être un crustacé copépode, fréquemment observé comme parasite cutané de certains poissons (lieus, labres).

Apparament, ce n'est pas un Anilocre (Anilocra frontalis) qui est une espèce sans yeux... La question reste ouverte.

Ce pourrait être un Cirolanidae...

 Comment from Stephen Keable
Hi Christophe,

the large eyes and the apparently prehensile nature of the legs (pereopods) suggest this isopod is in the family Cymothoidae (probably a juvenile/male) not the Cirolanidae. Cymothoid juveniles are free living but the adults are fish parasites as your caption suggests. The actual specimen would be needed to see if it were possbile to identify further but if it is juvenile I suspect this will not be possible.

Regards, Steve.
