Wed 25 September 2024:

The National Institute of Water and Atmospheric Research (NIWA) reveals the Australasian Narrow-nosed spookfish, found exclusively in the deep waters around Australia and New Zealand.Known as “ghost sharks” or “chimaeras,” these spookfish, relatives of sharks and rays, have skeletons entirely made of cartilage and haunting black eyes.

Named After a Special Family Connection
Research scientist Brit Finucci honors her grandmother by naming the new species Harriotta avia. “Avia means grandmother in Latin. I wanted to give this nod to her because she proudly supported me through my career,” said Finucci.

These deep-sea creatures, sometimes called ratfish or elephant fish, feed on crustaceans at depths of up to 2,600 meters (8,530 feet) using their unique beak-like mouths.

Previously believed to belong to a globally distributed species, the spookfish was found to be genetically distinct. “Harriotta avia is unique due to its elongated, narrow snout, large eyes, and long, broad pectoral fins,” Finucci explained.

A Challenge for Researchers
“Ghost sharks like this one are largely confined to the ocean floor,” said Finucci, adding that their hard-to-reach habitat makes studying them difficult, but discoveries like this are especially exciting.
