Deep, black seas off the coast of New Zealand have revealed the existence of a new species of ghost shark, sometimes known as “spookfish.” This finding, known as the Australasian narrow-nosed spookfish (Harriotta avia), is noteworthy since the species is limited to the waters surrounding New Zealand and Australia. These chimaeras, often known as ghost sharks, belong to the same class of cartilaginous fish as sharks and rays. They are distinguished by their beak-like teeth and are known for having smooth, scaleless skin. They usually eat crustaceans, such as shrimp and mollusks.
NIWA Fisheries Scientist Brit Finucci, who led the research that uncovered this new species, described Harriotta avia as having a unique appearance. “Harriotta avia is unique due to its elongated, narrow and depressed snout; long, slender trunk; large eyes; and very long, broad pectoral fins. It is a lovely chocolate brown color,” she said. The species was discovered during a research survey in the Chatham Rise, off the eastern coast of New Zealand near the South Island, in waters as deep as 2,600 meters (8,530 feet).
Ghost sharks like this one are difficult to study due to their deep-sea habitat, and little is known about their biology or conservation status. However, this discovery has shed light on their genetic and morphological differences from other species. Originally thought to be globally distributed, new research confirms this spookfish is distinct.
As a tribute to her grandmother, Finucci named the species Harriotta avia, signifying the species’ longstanding position in the shark family tree as well as her personal support. Although the IUCN does not officially designate any chimaeras as endangered, nearly one-third of sharks, rays, and chimaeras are threatened by overfishing.
It’s interesting to note that this ghost shark is not the only paranormal find. Just in time for Halloween, the frightening lineup was recently expanded to include the new species of fanged frog, Limnonectes cassiopeia, which was discovered in the Philippines.
