Cirri and tassel in Zeugopterus regius (Bonnaterre, 1788), Pleuronectiformes, Scophthalmidae
Résumé
Examination of photographs of live specimens in situ and preserved specimens of Eckström’s topknot [Zeugopterus regius (Bonnaterre, 1788), Pleuronectiformes, Scophthalmidae] shows previously undescribed appendages present on the eyed side and around the eyes. Some cirri are present between scales on the eyed side and above the eyes. A tassel-like element decorates the top of the left (non-migrating) eye, but not in all individuals. Its relationship with possible geographic or sexual dimorphisms is discussed.
