Scientists in New Zealand said Tuesday they have discovered a new species of "ghost shark", a type of fish that prowls the Pacific Ocean floor hunting prey more than a mile down.

The Australasian Narrow-nosed Spookfish was found living in the deep waters of Australia and New Zealand, according to scientists from Wellington-based National Institute of Water and Atmospheric Research (NIWA).

The specimens were discovered during research in the Chatham Rise, an area of the Pacific which stretches around 1,000 kilometers (621 miles) east near New Zealand's South Island.

Ghost sharks, or chimaeras, are related to sharks and rays, but are part of a group of fish whose skeletons are entirely made of cartilage.

Also known as spookfish, the ghost sharks have haunting black eyes and smooth, light brown, scale-free skin.

They feed off crustaceans at depths of up to 2,600 meters (8,530 feet) using their distinctive beak-like mouth.

"Ghost sharks like this one are largely confined to the ocean floor," said research scientist Brit Finucci.

Finucci gave the new species its scientific name "Harriotta avia" in memory of her grandmother.

"Their habitat makes them hard to study and monitor, meaning we don't know a lot about their biology or threat status, but it makes discoveries like this even more exciting."

The spookfish was previously thought to be part of a single globally distributed species until scientists discovered it is genetically and morphologically different to its cousins.

French Scientists Find New Blood Type in Guadeloupe Woman

A French woman from the Caribbean island of Guadeloupe has been identified as the only known carrier of a new blood type, dubbed "Gwada negative," France's blood supply agency has announced.

The announcement was made 15 years after researchers received a blood sample from a patient who was undergoing routine tests ahead of surgery, the French Blood Establishment (EFS) said on Friday.

"The EFS has just discovered the 48th blood group system in the world!" the agency said in a statement on social network LinkedIn.

"This discovery was officially recognized in early June in Milan by the International Society of Blood Transfusion (ISBT)."

The scientific association had until now recognized 47 blood group systems.

Thierry Peyrard, a medical biologist at the EFS involved in the discovery, told AFP that a "very unusual" antibody was first found in the patient in 2011.

However, resources at the time did not allow for further research, he added.

Scientists were finally able to unravel the mystery in 2019 thanks to "high-throughput DNA sequencing", which highlighted a genetic mutation, Peyrard said.

The patient, who was 54 at the time and lived in Paris, was undergoing routine tests before surgery when the unknown antibody was detected, Peyrard said.

This woman "is undoubtedly the only known case in the world," said the expert.

"She is the only person in the world who is compatible with herself," he said.

Peyrard said the woman inherited the blood type from her father and mother, who each had the mutated gene.

The name "Gwada negative", which refers to the patient's origins and "sounds good in all languages", has been popular with the experts, said Peyrard.

The ABO blood group system was first discovered in the early 1900s. Thanks to DNA sequencing, the discovery of new blood groups has accelerated in recent years.

Peyrard and colleagues are now hoping to find other people with the same blood group.

"Discovering new blood groups means offering patients with rare blood types a better level of care," the EFS said.
