And You Wonder Why I Fear The Seas

A member of the Stomiidae family, the black dragonfish is a deep-sea species occurring throughout the southern hemisphere at depths of around 2,000 meters (7,000 ft). Like many deep-sea species, black dragonfish undertake vertical migrations, swimming toward the surface at night to feed before descending back into the depths during daylight hours.

They also show an extreme case of sexual dimorphism. The female black dragonfish can reach 40 centimeters (16 in) in length. Along with many other mesopelagic predators, it can produce its own light via photophores situated along its body, under its eyes, and on the tips of its chin barbell. These can act as a lure to entice smaller prey, which are devoured using its huge barbed fangs, or to confuse its own predators. The males, on the other hand, are brown rather than black and barely reach 5 centimeters (2 in). They also lack teeth, chin barbells, and any sort of functioning gut, much like the male deep-sea anglerfish.
