Goblin Shark Video Captures Reveal Expanded Depth and Range

New Live Observations Extend Known Habitat
Two video recordings of goblin shark (Mitsukurina owstoni) were captured and published in *Journal of Fish Biology*. One shows a shark near an unnamed seamount northwest of Jarvis Island; the other records a shark on Tonga Trench slope southeast of Fiji. The footage was obtained by University of Hawaii at Manoa and Minderoo-UWA Deep-Sea Research Centre in 2024-2025.
Historical Context
First described in 1898, goblin shark is a “living fossil” and sole survivor of a ~125 million-year lineage. It was known only from rare fishing-line captures, after which individuals died quickly. It typically inhabits depths around 3,000 ft (? 914 m) and was previously recorded off United States, Australia, Japan, and Atlantic, Indian Ocean sites.
Contributors
Contributors include Aaron Judah, oceanographer at the University of Hawaii’s Deep-Sea Fish Ecology Lab, and Alan Jamieson, director of Minderoo-UWA Deep-Sea Research Centre. The work also used Inkfish Open Ocean Expedition aboard R/V Dagon, a baited bottom-lander camera, and ROV Hercules.
Chronology of Key Discoveries
- 1898 – species first described.
- 2019 – ROV Hercules captured footage near Jarvis Island.
- 2024 – bottom-lander on R/V Dagon recorded a goblin shark on Tonga Trench slope.
- 2025 – study published in *Journal of Fish Biology*.
Quantitative Findings
Goblin sharks reached 13 ft. The Tonga Trench sighting was ~700 m deeper than any prior record, about 2,300 ft deeper than expected. The expedition filmed 50 days of video between 800 m and 10,800 m; segment lasted ~20 seconds. Both are in Central Pacific.
Significance and Management Implications
Central Pacific range extension suggests a wider distribution. Authors propose adding goblin shark to management plans and biodiversity inventories. Study also underscores value of deep-sea video surveys for documenting elusive marine species.
Conflicting Reports & Gaps
Sources agree on the ~700 m depth extension; no direct conflict appears. However, only two observations exist, leaving substantial uncertainty about population size, distribution, and ecological role.
Verbatim Quotes
- “Seeing the most iconic of all the deep-sea sharks alive and looking healthy in its natural habitat is a unique honor,” — Aaron Judah, Oceanographer, University of Hawaii
- “The goblin shark is one of these deep-sea charismatic animals that I never thought we’d see alive,” — Alan Jamieson, Director, Minderoo-UWA Deep-Sea Research Centre
- “It's not only seeing it alive that was fascinating, but also the fact the Tonga Trench goblin shark was 700 metres deeper than previous known, making the deepest-known white shark.” — Alan Jamieson
- “New discoveries like this demonstrate that there is still so much to explore in our deep ocean home," Mr Judah said.” — Aaron Judah
- “Given the newly expanded geographic range of the goblin shark, this species can be included in regional management and a nation's biodiversity list.” — Study authors
Future Directions
Authors recommend adding goblin shark to management frameworks and national biodiversity inventories, and stress that continued deep-sea video surveys are needed to fill knowledge gaps on its distribution and ecology.
