Researchers at California's Monterey Bay Aquarium Research Institute spotted a deep-sea anglerfish in their exploration of the Monterey Canyon, a Pacific Ocean canyon as big as the Grand Canyon that starts close to the central California coastline.
These anglerfish are remarkable for the flashlight-like appendage that helps them lure prey. When a smaller fish or squid approaches, its huge jaws inhale the prey caught in its sharp teeth.
"These are ambush predators," says Bruce Robison, a senior scientist at the research institute who led the dive using a remotely operated diving vehicle operated from a nearby ocean research platform.
Black Seadevils like this Melanocetus are quite elusive. Robison, who spotted the Black Seadevil last week at a depth of 600 meters (1,900 feet), said he believes this is the first time such a creature was filmed alive and at depth.
