Abstract

Unusual development of a filamentous extension of the lower caudal-fin lobe was observed in eight male individuals of the Lessepsian migrant fish species Nemipterus randalli, collected from Gökova Bay, south-eastern Mediterranean Sea. It is suggested that this phenotypic trait is related to the highly successful invasion of this species in the eastern Mediterranean and may be associated with a shift towards either sexual dimorphism or a change in feeding behavior in a new environment.
