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.

An "amphibious mouse" with partially webbed feet that eats aquatic insects was among 27 new species discovered during a 2022 expedition to Peru's Amazon, according to Conservation International.

Scientists also discovered a spiny mouse, a squirrel, eight types of fish, three amphibians and 10 types of butterflies, Trond Larsen, head of Conservation International's Rapid Assessment Program, told Reuters this week.

He added that another 48 species found by investigators were potentially new, but needed further study.

The new species were found in Alto Mayo, a protected area with several ecosystems, Indigenous territories and villages.

"Discovering so many new species of mammals and vertebrates is really incredible, especially in such a human-influenced landscape as Alto Mayo," Larsen said.

The expedition between June and July 2022 was made up of 13 scientists plus local technicians and members of Indigenous groups.

"It was really fantastic to work so closely with the Awajun people. They have extensive traditional knowledge about the forests, animals and plants they live side-by-side with," Larsen said.

Among the new species, Larsen highlighted the spiny mouse that has stiff fur, the amphibious mouse, and a dwarf squirrel that measures 14 cm (5.5 in).

"(The squirrel) fits so easily in the palm of your hand. Adorable and beautiful chestnut-brown color, very fast," Larsen said. "It jumps quickly and hides in the trees."

Another favorite discovery was the blob-headed fish, a type of armored catfish, he said.

A total of 2,046 species were recorded during the 38-day expedition using camera traps, bioacoustic sensors and DNA sampling. Among them, 49 were classified as threatened, including the yellow-tailed woolly monkey and the tree monkey.

Larsen said the discoveries reinforced the need to protect the area.

"Unless steps are taken now to safeguard these sites and help restore parts of the landscape ... there's a strong chance they won't persist in the long term," Larsen said.
