The putatively luminous villous tissue in an abdominal pouch of a male specimen of the oceanic midwater shark Euprotomicroides zantedeschia is described. The epithelium within the pouch is probably stratified. The most conspicuous cell type is tall columnar cells, typically containing small cytoplasmic granules and a large inclusion. Cells with similar cytoplasmic characteristics, thought to be photogenic cells, are present in the epidermal skin photophores in other selachians which are known to be luminous.
