The anglerfish is one of most interesting of fish species out there and quite possibly one of the most terrifying to look at as well. Just this week, researchers from Monterey Bay Aquarium Research Institute released some rare footage of a black seadevil, one of many anglerfish families. The fish was caught 1,900 feet deep into waters during a dive at Monterey Bay, California.

Here's a quick picture of the beast. 


Anglerfish are known to be predatory. The fishing pole-like structure protruding from the head indicates that this black seadevil is a female. Females are known to use this "fishing pole" as a means of attracting its prey. Males, on the other hand, are typically much smaller in size compared to females and are parasitic in nature. Consequently, males require a female to survive and literally clasp onto a female counterpart via their pointy teeth. Slowly, once a male successfully finds and attaches onto a female, the two eventually physically join together. According to National Geographic, "a female will carry six or more males on her body." 

Since a sighting of such a fish is so rare, the black seadevil has since been taken in by researchers for further study.
