Dragons lurk in dark depths.

Dragonfishes (family Stomiidae) are cunning predators. Although they are strong swimmers, they prefer to lie in wait and ambush unsuspecting fishes and crustaceans. Most have dark skin—pigmented with some of the blackest blacks known in nature—to stay camouflaged from their prey. Some dragonfishes dangle a luminescent lure from their chins to entice prey. When a tasty morsel comes close, their big jaws open wide, and sharp teeth snap shut.

MBARI researchers have observed several different dragonfishes in the depths of Monterey Bay. The Pacific blackdragon (Idiacanthus antrostomus) and the longfin dragonfish (Tactostoma macropus) are the most commonly sighted species. Encounters with others are rare treats.
