Scientists have recently discovered a new species of ghost shark, known as the Australasian Narrow-nosed Spookfish, in the deep waters off Australia and New Zealand. This species was found in the Chatham Rise area by researchers from the National Institute of Water and Atmospheric Research. Ghost sharks, a type of chimaera closely related to sharks and rays, are known for their unique features such as a long snout and beak-like teeth. They typically reside on the ocean floor at depths of up to 2,600 meters, where they feed on crustaceans.
Named Harriotta avia in honor of the NIWA Fisheries scientist’s grandmother, this newly discovered species was previously thought to be part of a single global species but was later found to be genetically distinct. Ghost sharks are considered poorly studied due to their remote habitat and elusive behavior, but the Australasian Narrow-nosed Spookfish has been more extensively researched.
Despite this, there is still much to learn about ghost sharks, including their lifespan, population size, and ecological role. Researchers are continuously discovering new species, with the potential for more hidden secrets lurking in the depths of the ocean waiting to be uncovered. The discovery of this new ghost shark species highlights the importance of further exploring and understanding the mysteries of the deep sea.
