The world’s most unusual shark has been documented in its natural environment for the first time, as detailed in a groundbreaking study published in the Fish Biology Journal.
The Goblin Shark (Mituculina Ostni), known for its peculiar appearance, was spotted in 2019 by researchers from the University of Hawaii at Manoa near Jervis Island in the South Pacific.
This deep-sea goblin shark is famous for its retractable jaws, which enable it to lunge forward at speeds up to 3.1 meters per second to catch its unsuspecting prey. Fishermen often bring these sharks up from depths reaching 1,200 meters (3,940 feet), as indicated by a dead specimen.
“It’s an extraordinary privilege to witness one of the most iconic deep-sea sharks alive and thriving in its natural habitat,” stated Dr. Aaron Judah, the lead author of the research and a doctoral candidate in the Department of Oceanography at the University of Hawaii at Manoa.
“We were astonished by the depth at which this species was found. Observations from the Tonga Trench show it is nearly 700 meters deeper than previously recorded occurrences of this species.”
Video footage of the goblin shark was captured using a camera mounted on Hercules, an underwater drone operated by the University of Hawaii at Manoa. It was only later that Dr. Judah identified the fish from the recordings of the expedition’s livestream.
The second sighting of the goblin shark was achieved by a team from the Minderu UWA Deep Sea Research Center off the Tonga Trench using a baited camera attached to a bottom lander—an essential tool for oceanographic research on the ocean floor.
Goblin sharks typically reach lengths of up to 3.6 meters (12 feet), with their long, flat snouts comprising about one-tenth of their total length.
These elusive creatures are as enigmatic as their quirky looks, with fewer sightings reported daily compared to other mysterious deep-sea inhabitants like the giant squid or the ghost fish of the Mariana Trench.
Despite their mysterious nature, sporadic sightings of goblin sharks have increased in recent decades, with reports from locations such as the Canary Islands and the Japanese coast—even outside of their deep-sea natural habitat.
