    Malacosteus Niger has a tear-drop shaped, dark brown, suborbital photophore which is used to emit red light at an emission maxima of 710 nanometers. Removal of the top brown photophore layer causes a shift of the emission spectra to shorter wavelengths of around 650 nanometers.
    The yellow lens reduce the amount of blue light that reaches the retina and increases sensitivity to longer wavelengths, which benefits M. niger and its red bioluminescence. Yellow lens have also been identified in Echiostoma, which also produces red bioluminescence. Images showing morphological characteristics of Malacosteus niger.
    However, Malcosteus niger produces far-red bioluminescence and its longwave retinal sensitivity is enhanced by red-shifted visual pigments, a longwave reflecting tapetum and, uniquely, a bacteriochlorophyll-derived photosensitizer. The origin of the photosensitizer, however, remains unclear.
    Malacosteus has an elongated body with short, blunt snouts and large eyes that face forward, granting binocular vision. Unlike other stomiids, it has a single round nostril on each side in front of the eye. Relative to its size, Malacosteus has one of the widest gapes of any fish, with a lower jaw measuring one-quarter of the fish's length.
