Morphological, ultrastructural and immunohistochemical study on the skin ventral photophores of Diaphus holti Tåning, 1918 (Family: Myctophidae)

A further contribution to the knowledge of the photophore structure of the mesope-lagic fish Diaphus holti (Myctophidae) from the central Mediterranean Sea (Strait of Messina) is given by means of a structural, ultrastructural and immunohistochemical study, to describe the component structures of these luminescent organs.
