Host Selectivity of Nerocila Orbignyi (Guerin-Meneville, 1832) (Isopoda, Cymothoidae) with a Record of a New Host from the Sea of Marmara (Turkey)

Nerocila orbignyi (Isopoda, Cymothoidae) is reported for the first time on Mugil cephalus Linnaeus, 1758 (Pisces, Mugilidae) from Bandırma Bay (the Sea of Marmara, Turkey) during 2020. This paper aims to present the morphological characters of male of N. orbignyi from Turkey. Hosts infested with N. orbignyi are commented according to taxonomical status (order, families), ecological behaviours (habitat selections, feeding habits, school-solitary), morphological characters (scale types) according to current records. It may be said that N. orbignyi has been reported more frequently on fish belonging to the Perciformes order and Mugilidae and Sparidae families. It may also be said that this parasite selects also the fishes with carnivorous, demersal, schools, and migratory character.
