Scientists photograph and capture rare (and odd looking) melanocetus (“the Black Seadevil”) deep-sea fishResearchers with the Monterey Ray Bay Aquarium Research Institute acquired footage of the rare Melanocetus fish, more affectionately known as “the Black Seadevil”. These creepy critters are rarely seen in their natural deep-sea habitat. Scientists who captured the wonderful new footage of the Black Seadevil told reporters that the first thing they thought when the spotted the unusual species was “Aaaaagggghhhhh!!!!”

As you can see, the Black Seadevil is very, ah, different looking. The shining spot at the end of the “fishing pole” that protrudes from the fish’s head is a glowing lure. The anglerfish uses the light to attract prey in its deep, dark habitat.

The pictures of the Black Seadevil were taken from a remotely operated vehicle (ROV) at a depth of 1,900 feet. This specimen of Melanocetus is about 3 ½ inches long and was captured by the ROV and brought to the surface for further study.  It now lives in a large, dark, air-conditioned tank.

Encounters with deep-sea anglerfish are exceedingly rare and very little is known about them. It is believed that fewer than ½ dozen have ever been recorded by deep-diving research vehicles. This one was photographed off the coast of central California.

More about the Melanocetus Fish

The melanocetus deep-sea anglerfish lives in the bathypelagic zone of the ocean. They are typically found at depths of over 1000 meters and are known for their unique appearance and hunting tactics.

Melanocetus Fish Appearance

Melanocetus fish are easily recognizable due to their distinct appearance. Their body is small, measuring only a few inches in length, and their head is disproportionately large. They have large, sharp teeth and a bioluminescent lure on their forehead that they use to attract prey. The body of the fish is black, which helps it blend in with the dark environment of the deep sea. The bioluminescent lure is located on a long, thin stalk that protrudes from the top of their head. The lure itself is made up of bioluminescent bacteria that the fish has cultivated within its body. The bacteria emit a blue-green light that is used to attract prey.

Melanocetus Fish as predators

Melanocetus fish are ambush predators and use their bioluminescent lure to attract prey. Once the prey is close enough, the fish uses its large mouth and sharp teeth to capture and devour it. Their diet consists mainly of small fish and crustaceans, which are abundant in the deep sea. The bioluminescent lure is a key part of their hunting strategy, as it allows them to attract prey in the otherwise pitch-black environment of the deep sea.

Melanocetus Fish Reproduction

Melanocetus fish have a unique reproductive system. The males are much smaller than the females and do not have a bioluminescent lure. Instead, they rely on their sense of smell to locate a female. Once they find a female, they bite onto her and release an enzyme that fuses their tissues together. The male then lives the rest of his life attached to the female and provides sperm for fertilization. This unique reproductive strategy is known as sexual parasitism and is found in several species of deep-sea anglerfish.

Threats to the Melanocetus Fish

Melanocetus fish are not currently threatened by human activities, as they live in the deep sea and are not targeted by commercial fishing. However, their habitat is at risk due to climate change and ocean acidification, which could have a negative impact on their survival. The deep-sea environment is also under threat from deep-sea mining, which could have a devastating impact on the delicate ecosystems that exist in these environments.

Melanocetus fish are fascinating creatures that have adapted to life in the deep sea. Their unique appearance and hunting tactics make them a fascinating subject for marine biologists and ocean enthusiasts alike. However, their survival is threatened by the impact of human activities on the deep-sea environment. It is important that we take steps to protect the deep-sea environment and the creatures that call it home.
