Recent findings from a research team at the University of Hawaii have significantly broadened the known habitat of the goblin shark, both in terms of depth and geographical distribution. This species, one of the most elusive sharks on the planet, was observed in its natural environment for the first time.
Previously, sightings of goblin sharks were limited to instances where they were caught on fishing lines and brought to the surface, where they could be briefly observed by divers before dying. The breakthrough came when lead researcher Aaron Judah learned of a potential sighting during a 2019 expedition.
This expedition focused on deep-sea ecosystems near Jarvis Island, a wildlife reserve located approximately 2,400 kilometers south of Honolulu. Judah expressed surprise at the discovery, noting that the species was not previously known to inhabit the central Pacific region.
Upon reviewing footage from the expedition, Judah confirmed that the team had indeed documented a goblin shark during a live dive broadcast northwest of Jarvis Island. A second observation occurred in 2024, when the research team studying the Tonga Trench captured images of a goblin shark in its natural habitat using a baited camera.
Alan Jamieson, a professor and founding director of the Minderoo-UWA Deep Sea Research Centre, remarked on the significance of the 2024 sighting, stating, “The goblin shark is one of those charismatic deep-sea creatures that I never thought I would see alive, and the fact that it happened was astonishing. Learning that colleagues in Hawaii had also seen it was simply incredible.”
Judah described the opportunity to see this iconic deep-sea shark alive and healthy in its natural environment as a unique honor. He noted the unexpected depth at which the species was found, with observations from the Tonga Trench occurring nearly 700 meters deeper than previously recorded.
The new observations greatly expand the known habitat range of goblin sharks, both in terms of depth and geography. Judah emphasized that such discoveries indicate there is still much to explore in the deep ocean. Given the newly expanded range of the goblin shark, the species may now be considered for inclusion in regional management programs and national biodiversity lists, a recognition that was previously unfeasible due to a lack of awareness of its existence.
