- 09
Classified under the scientific name Melanocetus johnsonii, the humpback anglerfish belongs to the family Melanocetidae within the order Lophiiformes.

Roughly 50 percent of humpback anglerfish specimens caught in deep-sea research have been females, suggesting males may occupy different depth zones or remain largely uncollected by standard sampling methods.
- 07
Females of this species develop a hump-shaped body structure along their backs, which gives the humpback anglerfish its distinctive common name.
- 06
Humpback anglerfish females inhabit depths between 2,000 and 4,000 meters where sunlight cannot penetrate, relying entirely on their bioluminescent lures to hunt in absolute darkness.
- 05
Female humpback anglerfish possess teeth so large they cannot close their mouths, allowing them to consume prey nearly as large as their own bodies in the deep ocean.
- 04
At depths exceeding 4,000 feet in the Atlantic and Pacific Oceans, humpback anglerfish females produce their bioluminescent lures through symbiotic bacteria that glow without generating heat.
- 03
The bioluminescent lure of female humpback anglerfish contains bacteria that produce light through chemical reactions occurring in specialized photophores.
- 02
Male humpback anglerfish permanently fuse to females during mating, their bodies degenerating into reproductive organs that remain attached for life.
- 01
Extreme sexual dimorphism in humpback anglerfish results in females reaching 45 centimeters while males remain under 12 centimeters long.
