Pacific Blackdragon Fish: Slithering through the deep ocean, these sleek, serpent-like fish haunt tropical and temperate waters of the eastern Pacific. This species exhibits one of the most extreme cases of sexual dimorphism: The females grow to 16 inches, while the males only reach two inches. Females possess a lure, much like the anglerfish, and have barbells on their bottom jaw that sense prey. Some of their prey is bioluminescent, but they’re unlikely to catch a glimpse of these fish—their black stomachs act as camouflage.
