Dear Sergio, The shape of the body and the melanophores are similar, but Zeus faber doesn´t have those spines as described in literature. The picture is not good enough. I will put another one.
Please let me know your opinion again. Could it be one Scorpaenidae, Serranidae? It doesn´t seem to me, either Carangidae.
Yes. I've tried from my iPad. It seems the pages change each time I go there. Maybe it's a Caproidae. I must look for the species off Portugal. It doesn't seem to me Capros aper. I must check again. I'll let you know.
