The Australian Museum recently received a new intact goblin shark (Mitsukurina owstoni) specimen. The specimen is that of a young male and measures 1.26m in length. The shark was caught off Eden, New South Wales in water that was “several hundred meters deep.” This marks the fourth goblin shark in the museum’s Ichthyology Collection.
The goblin shark is a deep-water species that is rarely encountered by humans. It is known for its rather unconventional appearance, which includes pink skin, a flattened snout, and a jaw that can extend forward to capture prey. Adult goblin sharks are thought to typically reach lengths between 3-4m. Though, a specimen caught Gulf of Mexico in 2000 was estimated to be between 5.4 and 6.2m.
The Cape Eleuthera Institute recently shared a video featuring some footage of deep-water baited trial video surveys using the Medusa deep-sea survey equipment. The Medusa, on load to CEI from the Ocean Research and Conservation Assocation is capable of operating at depths as great as 2,000m. In addition to recording video footage, the Medusa also can record records conductivity, salinity, temperature, depth, and pressure.
The deep-water shark footage begins at about 2:25 and features Cuban dogfish (Squalus cubensis), sharpnose sevengill sharks (Heptranchias perlo) , and a bluntnose sixgill shark (Hexanchus griseus), who performs a Kamikaze style approach to the Medusa on its first appearance.
In addition to the shark footage, there is also video of other forms of deep-sea marine life who have come to check out the bait crates.
