Deep-sea white anglerfish

Haplophryne mollis

The Deep-sea white anglerfish is a ghostly white creature found at depths between 1000m to 4000m. The strange bulge between its eyes is a bioluminescent lure. The main fish above is a female and the tiny fish attached to her body are males. Since it is difficult to find mates in the deep ocean, male fish latch onto the female with hooked teeth. Even though the male fish are parasitic, they are eventually reduced to pockets of sperm that are used for reproduction. For all you fellas out there that have a rough time with the ladies, be thankful that you are at least not a bag of gonads floating through the ocean.

Black Dragonfish

Idiacanthus atlanticus

The Black Dragonfish are needle-like fish that migrate between 500m and 2000m in the deep ocean. Females are black with 6 stripes and lack a barbel, pelvic fins, and sharp teeth. Males, on the other hand, are dark brown and have a barbel, which is the light producing structure on its chin. Furthermore, it uses bioluminescence to detect prey instead of lure prey.
