A nightmarish sea creature caught off New South Wales, Australia, has ignited debate after a professional angler admitted he was baffled by it. The snake-like creature appears to be a type of large eel, with startled-looking eyes, a cavernous mouth and teeth like twisted nails. The teeth look like some kind of Moray eel. But the face is very blunt. It was about 9 feet long. Details of who caught it were not revealed, but it came out of the Pittwater estuary in southeast Australia. It was tan in color, with a muscular body, angular snout and an extra set of teeth growing from the roof of its mouth.

Rare deep-sea footage captures a blood-sucking parasite latched onto the body of a ghoulish gulper eel. In the video, the eel swims close to the camera before revealing a bright-red parasite protruding from its back with two string-like structures dragging behind it. Researchers from the Schmidt Ocean Institute spotted the elusive parasite while exploring seamounts in the Southeast Pacific Ocean along the coast of Chile. The parasite is likely a type of copepod — a small crustacean found throughout the world's oceans, representatives wrote in a Facebook post. Related: Watch rare footage of a shapeshifting eel with 'remarkably full tummy' swimming in the deep sea. Gulper eels are commonly known as pelican eels because of their ability to blow up their mouths like balloons to catch prey, similar to how pelicans use their stretchy bill pouches like fishing nets. They are found worldwide at depths around 1, to 9, feet to 3, meters. The new footage was recorded 6, feet 1, m below the ocean surface by a remotely operated vehicle. Parasites in this family are mesoparasites — meaning they live partially within the body of their host. These parasites use a branching structure called a holdfast to embed themselves into the flesh of their host. When one of these parasites anchors itself into the tissue, "it feeds on blood and fluids that pool at the attachment site," Bernot said. Pennellids have a complex life cycle , with some species having multiple hosts. Like other crustaceans, they begin their life as small planktonic larvae called nauplii. When one of these tiny organisms reaches a suitable host, it buries into the surface of the organism.

True eels are members of the order Anguilliformes, which includes plus species. Genetically speaking, electric eels have closer ties to catfish and carp. Shocking, right? Lined with wicked teeth, the jaws can shoot forward and grab struggling victims that are already trapped between the other set of jaws. The Sargasso Sea—a body of mid-ocean water whose borders are defined by various currents—is thought to be a major spawning ground for the species although other breeding sites might also exist. At first, baby eels are leaf-shaped larvae; later, they become 2- to 3-inch-long juveniles called glass eels; find new homes in brackish coastal habitats in yet another stage known as elvers; then, in the final stage before sexual maturity, they become yellow eels.
