Image: Malacosteus niger cam

Description: "A The head and lower jaw of a fresh specimen of Malacosteus. The edge of the reflector shows the position of the dark brown suborbital photophore (s-o) and whitish postorbital/accessory (p-o). B Similar image in longwave ultraviolet light showing the intense red fluorescence of the suborbital photophore. C-E Three ISIT video frames from a series of flashes from a single specimen, showing C the flashing of the SO alone, D the PO alone and E both PO and SO. The three frames are sequential, with an interval of 4 s between C and D and 2.6 s between D and E. The postorbital actually flashed 1 s after the suborbital but its intensity at that point caused the ISIT image to bloom." Scale bars: 5 mm
