Eustomias schmidti, more commonly known as the scaleless dragonfish, is one of the many species included in the family of Stomiidae.

Despite its small size, the scaleless dragonfish is a dangerous predator in the deep oceanic waters that uses its self-generated light to attract its prey.

The middle branch is stout and swollen with distal filaments that barely reach the barbel tip.

The side branches taper and extend far beyond the end of the barbel, with an exception in smaller specimens.

[3] The scaleless dragonfish occur in the Atlantic and Pacific oceans between 35–40° N and 30–35° S but are found mostly in boundary currents or equatorial water.
